STYRENE MALEIC ANHYDRIDE COPOLYMER with CAS 9011-13-6
Styrene maleic anhydride copolymer, abbreviated as SMA, is a polymer compound formed by copolymerization of styrene and maleic anhydride, CAS 9011-13-6. Styrene maleic anhydride copolymer is usually a white to pale yellow solid with good transparency and luster.
The glass transition temperature is between 80 and 100° C. Styrene maleic anhydride copolymer powder has good thermal stability and high-temperature resistance, and can maintain structural stability and physical properties at relatively high temperatures. Compatibilizer SMA has good mechanical strength and rigidity, and excellent impact resistance, tensile resistance and wear resistance.
Flexible instrument pads commonly used in American automobile manufacturers are made of single-piece molded substrates with a weight of 4 ~ 8 lb. At present, the market share of styrene-maleic anhydride copolymer resin instrument pad in North America can reach 40%.

Plastic additive: Styrene maleic anhydride copolymer can be used as a plastic modifier to improve the rheological properties of the melt, enhance the adhesion between the thermoplastic matrix and fillers or pigments, and increase the impact strength and heat deflection temperature of the products.
Coatings field: SMA STYRENE MALEIC ANHYDRIDE COPOLYMER can be used to prepare functional coatings and improve the adhesion, corrosion resistance and other properties of the coatings. Styrene maleic anhydride copolymer can also be used as an alkali-soluble resin in water-based inks and water-based varnishes.
Adhesive: Due to the presence of its active groups, compatibilizer SMA can be used to prepare high-performance adhesives.
Electronic materials: With excellent insulation performance and heat resistance, they are suitable for insulating materials and packaging materials in electronic and electrical appliances.
Other fields: Styrene maleic anhydride copolymer powder can also be used in textile and leather treatment, carpet cleaning, etc., and can also be used as an emulsifier or dispersant in various dispersion systems.
