Fluorocarbon rubber is a copolymer of monomers containing fluorine, mainly vinylidene fluoride and hexafluoropropylene or vinylidene and trichlorethylene. The fluorine content provides non-flammability. Fluoro rubber vulcanizates are characterized by a special heat and chemical resistance.It is resistant to ozone, ultraviolet radiation, aggressive chemicals, oils, fuels. Fluorinated elastomers exhibit low permeability of gases and minimal weight loss in vacuum.

Operating temperature range is from : -25 to + 200°C, for short duration increases to +230°C.

The fluorine vulcanizates are resistant to:

• mineral oils and greases also with ennobling additives,
• aliphatic and aromatic hydrocarbons
• flame resistant hydraulic fluids based on fosforoestrers and chlorinated hydrocarbons (HSC)
• synthetic oils for aircraft engines

Fluorinated vulcanizates are not resistant to:

• concentrated solutions of caustic soda and acids
• ketones, esters and ethers of low molecular weight, eg ethyl acetate, doksan
• organic acids such as acetic, formic
• Hot water and steam
