Perflurane rubber (FFKM), whose structure combines the main chain of tetrafluoroethylene (PTFE) with the branch chain and connecting parts of perfluoromethyl vinyl ether (PMVE), not only exhibits excellent resistance to high temperature and chemical corrosion (resistant to more than 1,600 chemical substances), but also retains the elastic properties of rubber.

In order to more comprehensively analyze the problem of surface roughness of EPDM extruded products, it becomes essential to combine the data analysis with the measurement parameters in actual production.

Protective wax, as an indispensable additive to rubber products, its core function is to prevent the aging of rubber in the process of use. Its mechanism of action is complex and diverse, including building physical barrier, trapping ozone molecules, delaying chemical reaction process and so on.
