Fluoro Carbon Rubber is a rubber molecule that contains fluorine, and there are various types depending on the fluorine content (i.e. monomer structure). The widely used hexafluoride fluororubber was first launched by DuPont under the trade name "Viton". High temperature resistance is better than silicone rubber, some have chemical resistance, resistance to most oils and solvents (excluding ketones and esters), weather resistance, and ozone resistance; Cold resistance is relatively poor, and the general temperature range for use is -20~250 ℃. The special formula can withstand low temperatures up to -40 ℃.

Fluororubber (FKM) is an organic elastomer formed by copolymerization of fluorinated monomers. Its characteristics include high temperature resistance up to 300 ℃, acid and alkali resistance, and oil resistance, which are the best among oil resistant rubbers. It has good radiation resistance and high vacuum resistance; Electrical insulation, mechanical properties, chemical corrosion resistance, ozone resistance, and atmospheric aging resistance are all excellent. The disadvantages are poor processability, high price, poor cold resistance, and low elasticity and breathability.

The temperature range for using O-ring fluororubber seals is -40 ℃ to+300 ℃. With the development of industry, O-type fluororubber sealing rings are widely used in automotive, electronic, aerospace, marine and other work environments that require high precision, high temperature resistance, high wear resistance, and harsh conditions. With the development of industry, fluororubber materials are also constantly improving and innovating. The following are the properties and application ranges of widely used fluororubber materials.

Advantages of O-type fluororubber sealing ring

It can withstand heat up to 250 ℃ and has the ability to resist most oils and solvents, especially all acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils. Excellent chemical stability, high temperature resistance, aging resistance, vacuum performance, mechanical performance, insulation performance, vacuum performance, mechanical performance, and insulation performance.

Disadvantages of O-type fluororubber sealing ring

Not recommended for use in ketones, low molecular weight esters, and mixtures containing nitrate. Cars, locomotives, diesel engines, and fuel systems.
