1Polyurethane elastomers are characterized by high strength, high elasticity, small deformation and good stretching force. 2Not easy to be corroded by fuel oil and machine oil, resistant to oil. 3Low weight, machinability, corrosion resistance, exceptional impact resistance. 4Polyurethane bar provides better tear and abrasion resistance and can be more readily bonded to another material. 5Widely used in metal processing stamping industry.
