Features | Oil resistance and aging resistance |
Application | With good cold resistance, wear resistance, low heat generation and high elasticity, good aging resistance, is a wide range of general synthetic rubber. It is mainly used to make the tread, transport belt, transmission belt, adhesive cloth, sole and so on after cleaning with natural machine. |
