Polyurethane is a kind of between plastic and rubber elastomer, its good comprehensive performance is common plastic and rubber. Polyurethane wheel polyurethane wheel according to the features of elastomer with good wear resistance, resistance to chemical attack, high strength, high elasticity, strong resistance to low pressure, shock absorption, tear resistance, radiation resistance, high load and shock absorption, etc. Good performance. Polyurethane wheels at the same time have a wide range of hardness, from shaw A10 & ndash; 100. Currently on the market has been beyond the shaw A100 or above products.
