Introduction

The main chain structure of the subchain is consistent with that of ordinary silicone rubber, while trifluoropropyl is introduced into the side chain. Therefore, fluorosilicone rubber perfectly combines the advantages of fluororubber and silicone rubber. It has the excellent oil resistance and high temperature resistance of fluororubber, and the softness and excellent high and low temperature resistance of silicone rubber. It is suitable for various harsh low temperature, high temperature and oil resistant occasions.

Product features:

□ Easy to process and color

□ Wide operating temperature range -60-230

□ Excellent oil resistance and non-polar solvent resistance

□ Suitable for manufacturing rubber products of various hardness, hardness (Shore A) 20-90

□ Excellent flame retardancy
