There are various types of rubber containing fluorine in the molecule, depending on the fluorine content (that is, the monomer structure). High temperature resistance is better than silicone rubber, has excellent chemical resistance, resistance to most oils and solvents (except ketones, esters), weather resistance and ozone resistance; cold resistance is poor, the general use temperature range is -20 ~250 ℃. Special formula can resist low temperature to -40 ℃.
advantage:
· Can resist heat to 250 ℃
· Resistant to most oils and solvents, especially all acids, aliphatic hydrocarbons, aromatic hydrocarbons, animal and vegetable oils
Disadvantages:
· Not recommended for ketones, low molecular weight esters and nitrate-containing mixtures
· Automobiles, locomotives, diesel engines and fuel systems.
· Seals for chemical plants
