High performance rubber O-ring

Fluorocarbon rubber is a rubber containing fluorine in the molecule, and there are various types according to the fluorine content (ie monomer structure). The widely used hexafluoro rubber was first listed by DuPont under the trade name "Viton". High temperature resistance is better than silicone rubber, excellent chemical resistance, resistance to most oils and solvents (except ketones, esters), weather resistance and ozone resistance; poor cold resistance, the general working temperature range is -20~250 °C. Special formula can withstand low temperature to -40 ℃.

An O-ring is a rubber O-ring with a circular cross-section. Because its cross section is O-shaped, it is called an O-ring. Rubber O-rings are the most widely used Seals in hydraulic and pneumatic transmission systems. Typically, rubber O-rings are rarely used for rotary motion seals. Rubber O-rings are generally installed in a groove with a rectangular cross-section on the outer or inner circle to play a sealing role.

Fluoroelastomer (FKM) is an organic elastomer made from fluoromonomers. Its characteristics are high temperature resistance up to 300 ° C, acid and alkali resistance, oil resistance is the best in oil-resistant rubber, good radiation resistance, high vacuum resistance; electrical insulation, mechanical properties, chemical resistance, ozone resistance, atmospheric resistance. Excellent aging performance. The disadvantages are poor processability, high price, poor cold resistance, low elasticity and breathability.

Operating temperature range: -40℃~+300℃. With the development of industry, fluororubber O-rings are widely used in automobiles, electronics, aerospace, ships and other fields that require high precision, high temperature resistance, high wear resistance, and harsh working environments. With the development of industry, fluororubber materials are constantly improving and innovating.
