Comment
|
Fluoro Elastomers have heat resistance up to 600°F. and resistance to a wide range of oils and solvents; especially all ahphatic, aromatic, and halogenated hydrocarbons, acids, animal and vegetable oils.
Fluoro Elastomers are not recommended for ketones, low molecular weight esters and nitro containing compounds.
