Fluorine Silicone Product Application Scope

Edit:Rizhao Tongrui Rubber Products Co.,Ltd  Date:Sep 11, 2017

Fluorosilicone rubber is a modified silicone rubber, that is, silicone rubber siloxane side chain on the methyl group by r-trifluoropropyl substituted products.

It has excellent oil resistance and solvent resistance. For aliphatic, aromatic and chlorinated hydrocarbon solvents, petroleum fuel, lubricating oil, hydraulic oil and certain synthetic oils (such as diester lubricants, silicic acid Ester hydraulic oil, etc.) at room temperature and high temperature stability are good, and can maintain flexibility. In the oil immersion conditions, the maximum temperature of up to 180 ℃. In the normal temperature and high temperature stability are good, long-term use in the range, 250 ℃ short-term use.

Product application range

Aviation industry: machine-resistant fuel oil, lubricating oil seals / contacts. Such as a variety of O-ring, fill, the whole tank seal, seal ring, sensor materials, diaphragm, fluorine silicon liner clamp.

The automobile industry: all kinds of vehicle seal ring, oil seal, diaphragm, catheter, valve lining and so on

Military industry: used in the need to withstand low temperature / oil / acid in the harsh environment, such as military aircraft hydraulic system infusion bellows, special vehicle doors and windows / mouth seal, sensor with a sensing material
