Common Brand Names:
Fluorel
 
General Description:  

General Description : A range of fluoropolymer elastomers whose formulation can be tailored to a reasonable extent to meet the needs of individual end-uses. They have high heat, oil and chemical resistance but indifferent low temperature performance. With the exception of Kalrez® perfluorinated elastomer, they are about the most highly temperature resistant of all commercially available elastomers.

Their main applications are seals, O-rings and linings.

NOTE As normally formulated, they are black and semi-conducting. We stock two items which are specially formulated and not black; these are insulating.
