4 Rubber classification
According to ISO
1629 is a grouping of rubber, but not limited to the following groups of rubber:
4:1 Group M
4:1:1 Chlorinated polyethylene (CM):
4:1:2 Chlorosulfonated polyethylene (CSM):
4:1:3 Ethylene-propylene copolymer (EPM) and ethylene-propylene-diene terpolymer (EPDM):
This standard cannot distinguish between these two types of rubber:
4:1:4 Fluorine rubber (FKM) with fluorine, perfluoroalkyl or perfluoroalkoxy substituents in the polymer chain:
This standard cannot distinguish between these rubbers:
4:2 Group O
4:2:1 Polyepichlorohydrin (CO), epichlorohydrin-ethylene oxide binary copolymer (ECO), epichlorohydrin-ethylene oxide-alkyl condensation
Glyceryl ether terpolymer (GECO):
