1、physical and chemical properties

Since the main chain is semi-inorganic silicone structure, it is based on the excellent properties such as heat resistance, cold resistance, high voltage resistance and weather resistance of the silicone material. , It also has excellent organic fluorine-resistant hydrocarbon solvent, oil, acid and alkali resistance and lower surface energy performance. Fluorosilicone rubber is a silicone rubber and fluorine rubber both the characteristics of the elastomer material. Compared with methyl vinyl silicone rubber, the biggest advantage is oil resistance, solvent resistance; and compared with fluorine rubber, although the resistance to alkane solvents in the little difference, but the aromatic solvent is better than fluorine rubber, its Good solvent only polar, small molecules of ketones. Fluorosilicone rubber heat resistance, cold resistance, compression and permanent deformation better, and the physical dependence on the temperature is small, from low temperature to high temperature have shown excellent performance. Can be widely used in aerospace, aviation, automotive, electrical, electrical, electrical, textile, machinery and construction and other fields, organic silicon materials can not meet the high temperature solvent resistance, oil, alkali resistance, acid rain, self-cleaning and other occasions sealed , Coating, liner and impregnation.

2、the temperature range

4、 color

Yellow, blue, can also be specified by the customer color.

5、 application

Fluorosilicone rubber is widely used in aviation, automobile, petrochemical, medical and health and electrical and electronic industries. Mainly used for high temperature and low temperature fuel delivery pipe seals, gaskets, fuel tank seals, shaft seals, contact with the fuel oil inlet and outlet seals, carburetor parts and diaphragm, hose, catheter, artificial organs, sealed Agents and adhesives.

1) Aeronautical film: Piston for tank, regulator for tank and tank for ventilating valve (for example, kerosene vapor at -55 ° C to 200 ° C and RP kerosene at 150 ° C) Cloth for the skeleton material of the cloth film);

2) static, dynamic seals: washers, cups, valves;

3) Automotive products: fuel level indicator sensor hose, atomizer pump diaphragm, fuel pump diaphragm, corrugated jacket, engine crankshaft seal, cylinder pad, fuel pump seal, tank cover gasket, fuel tank gasket, Seal;

4) other: fluorine resistant chlorine oil, fluorine resistant bromine oil, three chlorine resistant biphenyl, resistant to H2S solution, liquid nitrogen and other seals.
