Materials technology: FFKM [fully-flourinated perfluoroelastomer]
FFKM is one tough polymer, making it the material of choice for oil and gas exploration, aerospace and similarly demanding applications:
- temperature performance beyond most elastomers
- outstanding heat, ozone and weather resistance
- highly resistant to a wide range of solvents and chemicals
- low permeation and outgassing.
