(Fluoro Carbon Rubber)
A fluorine-containing rubber in the molecule has various types depending on the fluorine content (ie monomer structure). At present, the widely used fluorine hexafluoride 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 and esters), weather resistance and ozone resistance; cold resistance is poor, and the general use temperature range is -20 ~250 ℃. Special formula can withstand low temperature to -40 ℃. advantage:
· Can withstand heat to 250 ℃
· It is resistant to most oils and solvents, especially all acids, aliphatic hydrocarbons, aromatic hydrocarbons, animal and vegetable oils
· Automobiles, locomotives, diesel engines and fuel systems.
· Seals for chemical plants.
