Fluoroelastomer

A fluoroelastomer is a fluorocarbon-based synthetic rubber. Fluroelastomers generally have wide chemical resistance.

Composition

Several compositions of fluroelastomers exist including FKM (by ASTM D1418 standard, equivalent to FPM by ISO/DIN 1629 standard); perfluoro-elastomers (FFKM); and tetrafluoro ethylene/propylene rubbers (FEPM).

Performance

The performance of fluoroelastomers in aggressive chemicals depends on the nature of the base polymer and the compounding ingredients used for moulding the final products (e.g. O-rings, shaft seals). This performance can vary significantly when end-users purchase polymer containing rubber goods from different sources. Fluoroelastomers are generally compatible with hydrocarbons, but incompatible with ketones such as acetone and organic acids such as acetic acid.

gollark: I've twiddled the parameters of the hatchery on hatchlings a bit.

gollark: I did say "at some point", but I'll ask again later.

gollark: https://dragcave.net/lineage/qNHyr needs influencing to female - can anyone do that and hatch it at some point before it's due to hatch?

gollark: Coolful.

gollark: * not be able
