Characteristic:
SBR is a conventional synthetic rubber with grades as SBR-1500, SBR-1502 and SBR-1712. Compared with natural rubber, SBR possess outstanding abrasion-ageing- ozone-water- resistance, airtightness and homogeneity characteristics and could be blended with natural rubber in any proportion.
Application:
SBR-1500 is widely used for rubber products with carbon black as strengthening agent and of less colour requirements, such as tire tread compounds, renovated tire tread compounds, belts, hoses, footwears and other black rubber products. SBR-1502 could be widely used for bright-coloured and light-coloured rubber products, such as sidewall of the tires, transparent footwears, rubberized fabric, medical rubber products and other conventional colourful rubber products.
