Brief: High styrene rubber is a special variety of styrene-butadiene rubber. It is called High styrene rubber, also known as hard rubber, because of its high styrene content. It is a non-polar polymer composed of styrene and butadiene. It is prepared by emulsion copolymerization, and its chemical structural formula is:
—(CH 2 —CH=CH—CH 2 ) m —(CHC 6 H 5 —CH 2 ) n —white flake -
like particles, its heat distortion temperature is 70-90℃ , white solid, using a unique emulsion polymerization technology, copolymerized with high content of styrene monomer and butadiene monomer as a filling and reinforcing agent for rubber, and natural rubber, butadiene rubber, styrene-butadiene rubber and other dienes After the rubber-like compound is blended, the hardness, aging resistance, abrasion resistance, tear strength and tensile strength of the rubber can be improved, and it is easy to mix and process, easy to color, and has good thermoplastic and electrical insulation properties.
Application : High styrene rubber is suitable for manufacturing high hardness and low density products, 1. Footwear industry, rigid outsole, heel, rigid foam sole, imitation leather shoes, etc.; 2. Flooring material: rubber floor tile; industrial Products, such as rubber rollers, gaskets, hard rubber hoses and other sponge products; 3 Sports industry, such as three balls, roller skates; 4 Electrical insulating materials; Rubber sheet; 6 Toughening modification of ABS, AS plastics, etc.; Toughening modification of transparent PS sheet;
our company can produce different grades of High styrene rubber according to the different needs of customers. In recent years, high styrene has strengthened rubber Its role has been paid more and more attention by the rubber industry, especially in the automobile manufacturing industry. The addition of high benzene to tires is quietly emerging, so the potential market for high benzene rubber is very huge.
