HIGH STYRENE RUBBER HSR
High styrene rubber is a special variety of styrene butadiene rubber. It is a non-polar polymer prepared from the co-polymerization of styrene and butadiene latex. Chemical structure: —(CH2—CH=CH—CH2)m—(CHC6H5—CH2)n— It is white granule, non-toxic, odorless and combustible. Heat distortion temperature: 70-90°C, white solid. It is used as filling reinforcing agent to improve the hardness, aging-resistance, wear-resistance, tear strength and tensile strength of rubbers. Has excellent thermoplasticity and electrical insulating property.
Application: High styrene rubber is suitable for the manufacture of high-hardness and low-density products. 1. Shoe-making: hard soles, heel, rigid foam sole, imitation leather shoes etc.; 2. As floor materials: rubber floor tile; industrial products, like rubber roll, washer, hard rubber tube and other sponge products; 3. Sports industry: balls, rollerskate; 4. Electrical insulating material; 5. High-grade bike cover tyre; various printing pastern roller; slab rubber; 6. ABS, AS plastic;
In recent years,rubber field are paying more attention to reinforcement of high styrene rubber,especially in the automobile industry,such as applied in the tyre.therefore,potential market of HSR is very huge.
Performance: Accredited by experts who organized by the Shandong province Committee, our product has supplied a gap in China. Its major technical indicators have reached world leading level, and can be the complete substitute of imported products, such as Japan's NIPOL HS850, HS860&HS870, JSR0060 and KER1904 and HS260 etc.
