1, rubber is very soft and elastic, suitable for all kinds of sports, but the disadvantage is obviously that it is not wear-resistant. Pu is made of polyurethane, which is light in finished product, low in cost and unsuitable for water. It's very light, and its viscose ratio is better than rubber, and its comfort is better than rubber.

2. Rubber materials are mostly natural rubber with good elasticity, wear resistance and oil resistance. The finished product is heavier and more expensive than pu. The average rubber10.7 million tons, pu10.2 million tons, and rubber is about 5,000 yuan more expensive than pu.
