Difference between cpu outsole and rubber outsole

1, different materials. Cpu outsole: CPU is a cast polyurethane elastomer (CPU), which is a new polymer synthetic material between rubber and plastic. Rubber outsole refers to the sole made of rubber, and the rubber sole material can be divided into natural rubber or synthetic rubber.

2. The advantages are different. CPU is often used in casting processing, such as casters, mining, oil refining, textiles, printing machine cylinders, etc., and its finished products have strong wear resistance. The advantage of natural rubber is that it is very soft and has excellent elasticity, which is suitable for all kinds of sports and plays a role in shock absorption. The disadvantage is also obvious, that is, it is not wear-resistant. Indoor sports shoes mostly use natural rubber.
