Styrene-NPMI-MAH copolymers manufactured by Yangchen Tech are commonly used as compatibilizers and/or impact modifiers in plastic products, especially in the blending of styrenic polymers such as polystyrene (PS) and polyethylene (PE). among things. This copolymer helps improve compatibility between different polymer phases, thereby enhancing the mechanical and overall performance of the final product.   The specific addition ratio of styrene-NPMI-MAH copolymer depends on a variety of factors, including the desired properties of the final product, the composition of the base polymer blend, processing conditions and application requirements. Typically, it is added in relatively small amounts, usually as a weight percent of the total polymer blend.     In some applications, adding 1-5% by weight of styrene-NPMI-MAH copolymer can significantly improve the impact strength, thermal stability and melt flow properties of plastic products. However, it is critical to conduct thorough testing and optimization to determine the optimal dosage for specific formulations and applications.   Consulting with a polymer scientist or chemical engineer with expertise in polymer blending and formulation will help determine the appropriate dosage of styrene-NPMI-MAH copolymer for your specific plastic product. We can provide valuable insights and guidance for your specific application.   Welcome Inquiry!   Basic Physical Properties      N-phenylmaleimide terpolymer (NSM 1 #) Test Item Test Standard Test Data Molecular weight and distribution GPC Mw=60-110K，Pd=2.3-2.9 Glass transition temperature/℃ DSC 197.3-198.2℃ Initial decomposition temperature/℃ TGA 395-405℃ Density ASTM-D792 1.18-1.30g/cm3 Apparent —— white or light yellow powders     SM Heat Resistant Agent Modification Data       Component composites Vicat softening temperature/℃ (Yangchen Tech's Products ) Vicat softening temperature/℃ ( JAPAN Products) NSM/ABS=0:100 103.7 103.7 NSM/ABS =10:90 111.3 111.5 NSM/ABS =20:80 118.5 116.9 NSM/ABS =30:70 126.2 125.3

It can withstand relatively high temperatures without significant degradation, making it suitable for applications where heat resistance is crucial. For instance, in the manufacturing of certain automotive components that are exposed to engine heat or in electronic devices that generate heat during operation, SMA copolymer powder can provide the necessary durability and performance.   SMA copolymer powder also exhibits remarkable adhesion properties. It can adhere well to a variety of substrates, including metals, plastics, and composites. This makes it a valuable ingredient in adhesives and coatings formulations. When used in coatings, it not only helps in providing a strong bond but also can enhance the surface finish and resistance to environmental factors such as moisture and abrasion. In the adhesive industry, SMA copolymer powder can improve the shear strength and overall bonding performance of the adhesive, ensuring reliable and long-lasting joints.   Another area where ABS heat resistant modifier agent shines is in the field of polymer modification. It can be blended with other polymers to improve their properties. For example, when added to thermoplastic resins like polyethylene or polypropylene, it can enhance their rigidity and toughness simultaneously. This allows manufacturers to create materials with a better balance of mechanical properties, expanding the range of applications for these polymers. It can also improve the compatibility of different polymers in blends, reducing phase separation and improving the homogeneity of the final product.   In the packaging industry, SMA copolymer powder is finding increasing use. It can be incorporated into packaging films to improve their barrier properties against gases and moisture. This helps in extending the shelf life of packaged food and other perishable items. Additionally, its ability to enhance the printability of packaging materials.   SMA copolymer powder manufactured by Yangchen Tech is a versatile material that can be used in a wide range of industries. ABS heat resistant modifier agent has unique thermal stability, adhesion and polymer modification capabilities.

Improving ABS Heat Resistance: YangchenTech’s Styrene-NPMI-MAH Copolymer   Acrylonitrile-butadiene-styrene (ABS) is a widely used plastic prized for its strength, toughness, and ease of processing. However, its heat resistance is inherently limited.This blog will explain why ABS has these limitations and explore ways to improve its thermal performance—with a focus on chemical modifiers. Next, we’ll explore how YangchenTech’s styrene-NPMI-MAH copolymer, a powerful ABS heat modifier, can significantly improve ABS’s thermal stability.   Styrene-NPMI-MAH Copolymer Manufactured by YANGCHEN TECH  Weicome Inquiry!   Basic Information   Test Item Test Standards Test Data Molecular weight and distribution GPC Mw=12~16*104.PDI=2.0~3.0 Glass transition temperature/℃ DSC 160~210℃(Adjustable) Initial decomposition temperature/℃ TGA 395-405℃ Density  ASTM-D792 1.00~1.15g/cm3 Appearance NG Off-white powder     1.Why is standard ABS heat resistant?   ABS’s modest heat resistance limit stems from its molecular structure. As an amorphous material, it has no clear melting point—above the glass transition temperature (about 100°C), it softens. Even under moderate loads, unreinforced ABS deforms by about 1% at about 88-98°C. This is consistent with industry data: standard ABS can only be used continuously at temperatures around 80°C. In fact, once ABS approaches 100°C, it “becomes very soft and cannot hold its shape under pressure.” Its rubbery butadiene phase (Tg about -90°C) has good impact toughness, but no heat resistance. In short, ABS’s styrene-acrylonitrile matrix is ​​not rigid enough at high temperatures to maintain mechanical properties. As one review notes, ABS’s thermal stability is “quite low,” which limits its use in high-temperature environments, such as unreinforced automotive interiors.   2. Strategies to improve ABS’s thermal performance   To overcome these limitations, engineers have used several strategies:   High-temperature alloys (polymer blends): Blending ABS with engineering plastics with higher Tgs can improve overall heat resistance. For example, ABS/PC alloys (ABS combined with polycarbonate) can be made into materials with higher HDTs than ABS alone. Such blends generally improve tensile strength and stiffness, as well as thermal stability. For this reason, ABS-PC filaments are popular in the 3D printing community. Reinforced composites: Adding inorganic fillers can significantly increase ABS’s HDT. Glass fibers are particularly effective—about 30% glass fiber filler can increase ABS’s heat distortion temperature (HDT) by about 40°C (e.g., from about 90°C to about 130°C) by forming a thermally stable network. Talc or mica fillers can slightly increase the heat distortion temperature (about 10-15°C) by forming a heat-insulating layer. These reinforcements also increase stiffness, but may reduce impact strength. Heat stabilizers: Additives such as hindered phenol antioxidants or organometallic stabilizers can slow down the thermal oxidation of ABS, extending its service life at high temperatures. Flame retardant additives (bromine-based or phosphorus-based) not only reduce flammability but also enhance thermal stability, thereby increasing the distortion temperature of ABS. Annealing and processing: Careful processing (such as annealing molded parts) can relieve internal stresses and improve heat distortion performance. Optimizing mold design and curing conditions can also help parts withstand higher service temperatures. Chemical modification: Arguably the most effective method is to modify the ABS polymer itself, either by copolymerization or grafting. Introducing rigid monomers into the ABS backbone can significantly increase its Tg and heat distortion performance. This led us to develop Styrene-NPMI-MAH terpolymers, a class of heat-resistant ABS modifiers developed and produced by Yangchen Tech.   3. Styrene-NPMI-MAH copolymer: a high-performance ABS modifier   Styrene-NPMI-MAH copolymer (also known as NSM copolymer) is a random terpolymer of styrene, N-phenylmaleimide (NPMI), and maleic anhydride (MAH). Its high heat resistance comes from its aromatic rigid NPMI units and polar MAH groups. YangchenTech's copolymers can be formulated to have glass transition temperatures well above 150°C.     N-Phenylmaleimide Manufactured by YANGCHEN TECH Weicome Inquiry!
