Styrene Maleic Anhydride Copolymer (SMA) is a high-performance copolymer made of styrene and maleic anhydride. Due to its excellent thermal stability and compatibility, it is widely used in the field of plastic modification, especially in ABS resin. As an efficient modifier, SMA can significantly improve the heat resistance, mechanical properties and processing performance of ABS, providing a reliable solution for a variety of industrial fields.   Main applications of SMA in ABS resin 1.Improve heat resistance ABS resin is widely used in home appliances, automobiles and electronics, but its poor heat resistance limits its use in high temperature environments. By adding SMA to ABS, its heat deformation temperature (HDT) can be significantly increased. Experimental data: After adding 10% SMA, the heat deformation temperature of ABS can be increased by 5–10°C. Advantages: Modified ABS can be used in high-temperature environments such as automotive interior parts and electronic product housings. 2.Improve mechanical properties The addition of SMA can not only increase the hardness and tensile strength of ABS, but also improve its impact performance. Application scenarios: In the field of engineering plastics requiring high strength, such as tool housings, medical equipment components, etc. 3.Improve processing performance The high compatibility of SMA in ABS resin enables it to improve fluidity in the molten state, thereby enhancing the efficiency of injection molding and the surface finish of the product. Advantages: Reduce molding defects, improve product appearance quality, and meet the needs of high-end appearance parts. 4.Improved chemical resistance The polar groups of SMA can improve the resistance of ABS to chemical reagents, making it more suitable for use in harsh environments. Typical applications: Chemical equipment housings and corrosion-resistant containers.   Basic Infomation     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   Why choose Yangchen Tech's SMA products? 1.High Purity and Excellent Quality The purity of SMA provided by Yangchen Tech can reach 99%, ensuring its excellent modification effect in ABS.

Enhancing Impact Resistance in Plastics SMA Copolymer plays a critical role in enhancing the impact resistance of plastic products. It is often used as a modifier in the production of engineering plastics, such as ABS (Acrylonitrile Butadiene Styrene) and polystyrene. When added to these materials, SMA copolymer significantly improves their strength and durability without compromising flexibility. This makes it an essential ingredient in producing products that need to withstand stress, impact, and high temperatures.   2. Adhesive and Coating Applications The high reactivity of SMA makes it an excellent choice for adhesives and coatings. By combining SMA with other resins or polymers, manufacturers can create strong, durable bonding agents. This is particularly useful in industries where adhesive strength and resistance to environmental factors are critical. Whether it's in automotive applications, electronics, or packaging, SMA-based adhesives provide a reliable solution for manufacturers.   3. Plastic Alloying and Blending SMA is widely used to enhance the properties of plastic alloys. It acts as a compatibilizer, helping to blend otherwise incompatible polymers. In plastics, SMA improves the overall processing capabilities and enhances mechanical properties, especially when combined with high-performance polymers like polycarbonate (PC), polyphenylene oxide (PPO), or polyphenylene sulfide (PPS). By creating a more homogenous blend, SMA improves the structural integrity of plastic parts used in demanding environments.       4. Applications in Automotive Plastics The automotive industry relies heavily on advanced materials that offer durability, strength, and resistance to heat and wear. SMA Copolymer is often used in automotive applications such as interior trim, bumpers, and other plastic components. Its ability to improve impact resistance, along with its excellent thermal stability, makes it an ideal choice for manufacturing durable automotive parts that can withstand extreme conditions.   5. Medical Plastics and Devices Styrene Maleic Anhydride Copolymer ’s high purity and biocompatibility make it suitable for use in medical devices and equipment. Its excellent chemical resistance ensures that medical plastics maintain their integrity when exposed to harsh cleaning agents or sterilization processes. Additionally, its strong bonding ability makes it ideal for creating medical products that require long-lasting durability.   Why Choose Styrene Maleic Anhydride Copolymer for Your Plastic Manufacturing Needs?
