Sealing lip
For bisphenol-cured VDF/HFP/TFE polymers, calcium hydroxide level should be low and magnesium oxide level should be high to promote adhesion to metal inserts. Thermal black or mineral fillers generally give good adhesion.3 For most adhesive systems, it is necessary to limit postcure temperatures to about 200°C (392°F).3
The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
