Styrene-butadiene rubber 1502 is a general-purpose emulsion styrene-butadiene rubber. It is characterized by high wear resistance and high elasticity, and is a basic raw material widely used and well-suited in the rubber industry. Unlike specialized rubber, it has outstanding cost-effectiveness and is easy to use. It is made from butadiene and styrene as monomers through emulsion polymerization technology. It is in a light yellow block or granular form, with no obvious irritating odor. It has good elasticity and strong wear resistance, and is suitable for various rubber products such as tires, rubber shoes, rubber tubes, and sealing parts, while also balancing processing performance and usage performance.
Product advantages
The core advantage is its outstanding wear resistance, which can significantly extend the service life of rubber products and reduce wear; it has excellent elasticity and good rebound performance, suitable for scenarios requiring vibration reduction and buffering; it has strong processing adaptability, with smooth mixing and vulcanization, and is not prone to sticking to the roller or burning, making it suitable for large-scale production; it has good compatibility with natural rubber and other synthetic rubbers, allowing for arbitrary blending and adjustment of product performance; it has low cost and high cost-effectiveness, making it the preferred raw material for general rubber products, and its aging resistance and fatigue resistance are superior to ordinary natural rubber.
