Material / Colour Hardness Temperature resistance Field of application Remarks
EPDM
black
peroxidic cross-linked
70 -75 ± 5
Shore A
-40°C thru + 150°C hot water, steam (thru 180°C) food- and pharmaceutical industry
FKM / FPM
black or red
peroxidic cross-linked
70 -80 ± 5
Shore A
-40°C thru + 200°C excellent resistance against aromatic solvent, chemicals, etc., as well as at high temperatures solvent, chemical- and food industry
FFKM
black
peroxidic cross-linked
75 ± 5
Shore A
-10°C thru is + 230°C outstanding chemical and thermic resistance solvent, chemical- and pharmaceutical industry
FVMQ (Fluor-Silikon)
red, blue or transparent
peroxidic cross-linked
70-80 ± 5
Shore A
-50°C thru + 150°C special resistance against aromatic hydrocarbon compounds, oils, etc., and at low temperatures food industry
