High-Tg Bismaleimide Resin Manufactured By Yangchen Tech

In the high-performance polymers, bismaleimide resin (BMI) stands out for its exceptional thermal stability, mechanical strength, and electrical properties. Yangchen Technology specializes in BMI (CAS: 13676-54-5) with a focus on one key performance metric: glass transition temperature (Tg). Our BMI resins boast Tg values ​​exceeding 340°C, and custom formulations can reach temperatures exceeding 400°C.

Why the Tg of Bismaleimide Resin is Important?

The glass transition temperature (Tg) is the point at which a polymer transitions from a hard solid to a softer, rubbery state. For applications in the aerospace, electronics, and automotive industries, a high Tg ensures:

• Dimensional stability under thermal stress.
• Mechanical properties (e.g., strength, modulus) maintained at elevated temperatures.
• Resistance to deformation during sustained high-temperature operation.

Standard epoxy resins typically have Tg values ​​below 200°C, limiting their use in high-end applications. In contrast, our BMI resins achieve Tg values ​​as high as 400°C through molecular design and compounding. For example, our N,N'-4,4'-diphenylmethane bismaleimide (CAS: 13676-54-5) exhibits a Tg of 340°C after curing for 10 hours at 280°C.

Unlocking the highest performance of engineering plastics with advanced thermal stabilization technology

Exploring Heat-Resistant ABS

Acrylonitrile-butadiene-styrene copolymer (ABS) is a widely used engineering plastic, prized for its exceptional toughness, rigidity, and ease of processing. However, standard ABS suffers from a significant limitation: its heat deflection temperature (HDT), typically ranging from 85°C to 95°C, restricting its use in high-temperature applications such as automotive parts, electronic housings, and industrial equipment. To overcome this shortcoming, manufacturers are constantly searching for effective thermal modifiers that balance performance, cost, and processing efficiency. Among these solutions, N-phenylmaleimide (N-PMI) has emerged as a leading additive for thermal enhancement of ABS. This article will explore the science behind N-PMI's effectiveness, aiming to provide high-performance N-PMI solutions for industries worldwide.

1. The Science Behind N-PMI: How It Improves ABS's Heat Resistance

N-PMI is a rigid cyclic monomer with a molecular structure consisting of 1,2-disubstituted vinyl groups embedded in a five-membered ring. When copolymerized with ABS or blended as an additive, it acts as a "molecular scaffold," restricting the mobility of the polymer chains. This restriction raises the glass transition temperature (Tg) of ABS, directly improving its heat resistance without compromising its mechanical integrity. Key mechanisms include:

- Enhanced Chain Rigidity: The phenyl and imide groups in N-PMI introduce steric hindrance, reducing chain rotation and improving thermal stability.

- Synergistic Copolymerization: N-PMI binds to the ABS polymer during the synthesis process, forming covalent bonds that stabilize the matrix and prevent thermal degradation. Research has shown that adding 10% N-PMI to ABS can produce ultra-high-heat-resistant ABS with an HDT of 125-130°C, a 30-40°C improvement over unmodified ABS.

2. Why N-PMI Outperforms Other Thermal Modifiers

While other additives (such as glass fiber, mineral fillers, or other imides) can improve heat resistance, they often sacrifice processability, impact strength, or surface finish. N-PMI offers the following unique advantages:

- Balanced Performance: It simultaneously enhances heat resistance, tensile strength, and melt processing.

- Low-Dosage Efficiency: Even a 1% addition can increase the HDT by 2°C, enabling precise calibration for cost-sensitive applications.

- Compatibility with Additives: N-PMI works synergistically with stabilizers, pigments, and flame retardants, making it an ideal choice for multifunctional composites. In contrast, fillers such as talc or silica can reduce toughness, while other thermal stabilizers typically require higher addition levels, increasing viscosity and complicating processing.

In the dry-mix mortar industry, the performance of redispersible polymer powder (RDP) directly determines the bonding strength and flexibility of tile adhesives, exterior wall putties, and thermal insulation mortars. As the source of RDP production, the physicochemical properties of VAE emulsions form the cornerstone of all these properties. Today, we will delve into two specialized VAE emulsions designed specifically for RDP production—DiverSol 628 (VAE CW40-758) and DiverSol 688 (VAE CW40-718).

1. Balance between High Solids Content and Rheological Properties

For RDP (polymer powder) manufacturers, spray drying is the most energy-intensive process. The solids content of the emulsion raw materials directly affects production efficiency and energy costs. DiverSol 628 and DiverSol 688 demonstrate extremely high industrial economics in this regard.

In the VAE emulsion field, a solids content of around 60% is considered high. This means that the amount of water that needs to be evaporated during the spray drying process is significantly reduced. Compared to conventional 55% solids content emulsions, using the DiverSol series not only significantly reduces heat consumption but also substantially increases the unit output of spray towers.

Besides solids content, viscosity is crucial for atomization performance. DiverSol 628/688 have a viscosity range of 500 ~ 4000 mPa·s (25℃). This wide viscosity range, combined with its excellent flow properties, provides powder manufacturers with a wide process window:

• Good atomization: Appropriately low viscosity helps the emulsion form tiny droplets at the nozzle, resulting in more uniform particle size distribution in the dried powder, and better flowability after blending.
• Shear stability: Under high-speed pumping and spray shearing, the emulsion remains stable and is less prone to emulsion breakage and nozzle clogging.

Furthermore, both products use polyvinyl alcohol (PVA) as a protective colloid system. This system is standard in RDP production because polyvinyl alcohol not only stabilizes the emulsion but also acts as a protective film during the redispersibility of the adhesive powder, preventing the powder particles from clumping in water and ensuring rapid dispersion of the final dry mortar after water addition.

2. Differentiated Formulation Strategy Based on Tg Value

Although DiverSol 628 and 688 are highly consistent in their basic physical properties (appearance, solid content, viscosity, pH), they take two completely different technical directions in their core thermal performance indicator—glass transition temperature (Tg), targeting "rigid" and "flexible" applications respectively.

2.1 DiverSol 628: High Tg Leads to Rigidity and High Strength

♣ Tg Range: 10 ~ 20°C

♣ Technical Characteristics: A Tg higher than room temperature means that the movement of polymer molecular chains is restricted after film formation, resulting in a film with higher hardness and cohesiveness.

♣ Application Advantages: RDP produced using 628 is more suitable for applications requiring high bond strength and surface hardness. For example:

• Tile adhesive: Provides strong tensile strength, preventing heavy tiles from slipping.
• Floor mortar and self-leveling compound: High Tg helps improve the abrasion resistance and hardness of the floor surface.
• Gypsum-based applications: Enhances the strength of gypsum products.

2.2 DiverSol 688: Low Tg provides flexibility and crack resistance.

♣ Tg range: -15 ~ 0℃

♣ Technical characteristics: Significantly lower Tg than room temperature, the film is in a highly elastic state after formation, the film is soft, and has excellent elongation.

♣ Application advantages: RDP produced using 688 has its core selling points in flexibility and weather resistance. It effectively absorbs the deformation stress of the substrate, suitable for:

• External wall insulation systems: Prevents cracking of the insulation layer in environments with large temperature variations.
• Flexible putty: Provides excellent crack resistance, adapting to minor vibrations or settlement of the wall.
• Repair mortar: Provides necessary bridging ability when repairing old and cracked substrates.

3. Industrial Compatibility and Green Environmental Protection

In actual industrial production, VAE emulsions not only need excellent performance but also must possess good "compatibility," meaning they must be compatible with other raw materials.

3.1 Broad Chemical Compatibility

DiverSol 628/688 were formulated with the complexity of downstream applications in mind. These two emulsions typically exhibit good compatibility with various thickeners, plasticizers, solvents, and fillers. This is crucial for RDP manufacturers, as anti-caking agents or other modifying agents are often added to the emulsion before spray drying. Good compatibility ensures the homogeneity of the mixture, preventing stratification or flocculation.

3.2 Environmental Protection and Aging Resistance

With increasingly stringent GB standards for the environmental protection of building materials, the environmental properties of raw materials have become a critical indicator.

• Plasticizer-Free Design: Both products are formulated without plasticizers. This means that the film-forming flexibility of the emulsion comes from the internal plasticizing effect of the ethylene monomer, rather than from added small-molecule plasticizers. This not only prevents later-stage brittleness caused by plasticizer migration but also ensures excellent aging resistance.
• Low Residual Monomer: The residual vinyl acetate monomer content is strictly controlled below 0.5%, making it an environmentally friendly product.

3.3 Storage and Handling Guidelines

While the product boasts excellent performance, proper handling is equally important. Due to the presence of trace monomers, it is recommended to handle the product in a well-ventilated environment and wear protective equipment. Storage temperature should be controlled between 5°C and 40°C; freezing is strictly prohibited. It is particularly important to note that if the product has undergone long-distance transportation or long-term storage (shelf life 6 months), it is recommended to filter and stir before use to eliminate any potential lumps or crusts.

In the field of building waterproofing, polymer cement waterproof coatings have always been a market favorite due to their environmental friendliness, high film strength, and good compatibility with damp substrates. As the core raw material of JS coatings, the performance of the polymer emulsion directly determines the success or failure of the final waterproof layer. Today, we will delve into DiverSol 779P (VAE CW40-705) and DiverSol 777 (VAE CW40-705). By interpreting the data of these two products, which conform to GB/T 23445-2009 Type II standard, we will analyze the key technical aspects of high-performance waterproof emulsions in practical applications.

1. Technical Characteristics and Performance Highlights of Two Special VAE Emulsion

Both DiverSol 777 and 779P are plasticizer-free VAE Emulsion (Vinyl Acetate–ethylene Copolymer Emulsion) , presenting as a milky white water-based system. They maintain relatively consistent key indicators such as solid content, viscosity, pH, and glass transition temperature (Tg), which helps to maintain stable performance in different application scenarios.

♠ Industry Significance in Performance:

• Low Tg for Flexibility: Suitable for Type II waterproof coatings requiring low-temperature flexibility and crack resistance; the film exhibits good elongation after drying, adapting to slight substrate displacement and temperature changes.
• Excellent Compatibility with Cement Systems: The PVA protective colloid improves the dispersibility of the emulsion when mixed with cement and fillers; significantly improves the sag resistance and thixotropic properties of cement paste.
• Plasticizer-Free Formulation: Reduces VOC emissions and enhances environmental friendliness; more stable in the formulation, preventing performance degradation due to migration.
• Adaptability to Wet Environments: Forms a film on damp, cold substrates without chalking or early cracking.

2. Application Logic and Formulation Synergy in Waterproof Building Coatings

2.1 Mechanism of Action in Waterproof Coating Systems

♣ VAE emulsions play three roles in cement-based waterproof coatings:

• Providing flexibility: filling the "brittleness gap" of the cement system;
• Improving water resistance: forming a continuous polymer film in the pores after cement hydration;
• Promoting workability: improving thixotropy, reducing sagging, and improving the smoothness of application.

The low Tg characteristics of DiverSol 777 and 779P enable the polymer phase to form a continuous film structure at room temperature or even low temperature, thereby effectively improving the coating density. It forms an interpenetrating network (IPN) structure with the cement hydrate, enhancing adhesion and crack resistance, which are fundamental properties that Type II waterproof coatings must meet.

2.2 Key Performance Improvement Points in Waterproofing Systems

(1) Improved Flexibility and Crack Resistance

The addition rate of the emulsion is usually 10–20% of the total mass of the system. The DiverSol series can achieve the following within this range:

• Increased tensile strength
• Increased elongation
• Buffering ability for mortar shrinkage cracks

(2) Anti-sagging and workability

779P emphasizes "good anti-sagging performance" in its description. Its thixotropy is suitable for:

• Facade construction
• Multi-corner structures such as bathrooms
• Stability control of thick coating operations

(3) Durability and water resistance

The polyvinyl alcohol protective colloid system after film formation can make the emulsion evenly distributed in the cement pores:

• Reduce water absorption
• Improve freeze-thaw cycle stability
• Delay the alkaline erosion of cement paste

(4) Strong substrate adaptability

Both emulsions can be applied under "low temperature or high humidity conditions", especially suitable for:

• Rainy season construction areas
• Underground structures
• Brick and concrete building bases that are prone to dampness

3. Engineering value, storage and transportation and production operation points

3.1 Engineering value manifestation

In building engineering applications, waterproofing systems usually face challenges such as diverse substrates, complex construction environments and high durability requirements. The selection of a suitable VAE emulsion not only affects product test indicators but also long-term operational stability.

The value of DiverSol 777 and 779P to engineering projects is mainly reflected in:

(1) Improved overall construction efficiency

• Good thixotropy, easier application, and reduced rework
• Strong adaptability to wet substrates, eliminating the need for prolonged drying of the substrate

(2) Effectively extends the service life of the waterproofing system

• The continuous polymer phase reduces the path of moisture intrusion
• Strong crack resistance, especially suitable for areas with slight structural movement, such as bathroom corners and roof panel joints

(3) Wide range of applications

• Waterproofing for bathrooms, kitchens, and balconies\Basement and foundation protection layers
• Roof coatings
• Flexible waterproofing primers for interior and exterior walls
• Premixed waterproofing slurry for engineering projects

(4) Compliant with environmental trends

• Plasticizer-free, water-based, and low-residue, helping the product pass environmental building material certification or meet VOC requirements

3.2 Storage Specifications

(1) Storage Environment and Shelf Life

• Temperature Control: The emulsion must be stored in a sheltered area and must not be frozen. Storage temperature should be strictly controlled between 5°C and 40°C. Once VAE emulsions freeze, they are usually irreversible after demulsification, resulting in direct economic losses.
• Shelf Life Management: Under suitable conditions and in their original, unopened packaging, DiverSol 779P and 777 have a minimum shelf life of 6 months. It is recommended that factories implement a "first-in, first-out" (FIFO) inventory management principle.

(2) Pretreatment and Usage Precautions

• Filtration and Stirring: During transportation and storage, soft lumps or a skin may form on the surface of the emulsion, a common physical phenomenon in polymer dispersions. Therefore, filtration is strongly recommended before use. Especially if the product has been stored for a long time, thorough stirring is essential before use to ensure homogeneity.
• Preservative Treatment: Preservatives are added to the product at the factory to prevent microbial contamination. However, once the container is opened or transferred to another storage tank, the original preservative system may be insufficient to resist new microbial attacks. If the product cannot be used immediately, the user must take appropriate precautions (such as sealing for storage) or add a suitable preservative after transfer.

(3) Safety Precautions

• Although the DiverSol series is considered safe for its intended use, as a chemical feedstock, it contains trace amounts of residual vinyl acetate monomer (controlled below 0.5%). Therefore, adequate ventilation should be maintained in the operating area.
• Operators should wear protective clothing, gloves, and goggles. In case of skin or eye splashes, rinse immediately with water.

Techniques for processing TPU: injection molding, extrusion, calendering and blow molding

TPU can be processed by a variety of techniques including injection molding, extrusion, blow molding and calendering.

Injection molding is by far the most important technique for processing TPU material. TPU are easily molded into shapes such as shoe sole, wheels, electronic parts, seals, toys, gaskets, orthotics as so on.

TPU are easily extruded into shapes such as tubing, wire & cable. Unlike injection molding, extrusion can be used to produce a very good surface finish. For best results, use extrusion grade TPU materials

Another important process is extrusion blow molding in which air is blown into the mold to create the desired shape when molten plastic is extruded into a mold. Extrusion blow molding used to produce even complex hollow parts such as shoe cushion, car anti vibration part, bottles and containers.

Calendering is a method often used for coatings applications. It is widely used as a means of coating Synthetic Leather and fabric. Calendering grade TPU features with no sticky on roller, low torque, workable for embossing, excellent adhesion and chemical resistance. TPU Calendering synthetic Leather is mainly for sofa seat, wall decoration, sports mat, luggage, car interior, and ship seat. Koslen grade B-785AL and S-670AL are widely used in Calendering process.
