High styrene rubber is a special variety of styrene butadiene rubber. 

 Brief

        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.
