Here is the English translation of the basic information about fluorosilicone raw rubber:

Basic Information of Fluorosilicone Raw Rubber

Definition: Fluorosilicone raw rubber is a kind of high-molecular polymer with a silicon-oxygen 烷 (siloxane) main chain and side chains containing fluoroalkyl, methyl, and vinyl groups. It belongs to thermosetting fluoro silicone elastomers².
Appearance: Usually presents as a colorless or slightly yellow transparent colloid without mechanical impurities¹.
Density: Generally between 1.22 and 1.26¹.

Performance Characteristics

High and Low Temperature Resistance: It integrates the advantages of fluoro rubber and silicone rubber, with a wide service temperature range. It can be used in environments from -50°C to 220°C, and some products can even be used from -60°C to 200°C¹³.
Oil and Solvent Resistance: It has excellent oil and solvent resistance, showing good tolerance to various oils, organic solvents, etc., and can maintain stable performance in oil media and chemically corrosive media environments¹³.
Mechanical Properties: Fluorosilicone rubber made from fluorosilicone raw rubber has good mechanical properties, such as tensile strength, tear strength, and wear resistance, which can meet the use requirements of different application scenarios².
Insulation Performance: It has good insulation performance and can be used in the field of electrical insulation¹.
Gas Permeability: It has low gas permeability and can effectively block the passage of gases.
