Color – black/BLUE EPDM Elastomers
EPDM | FDA can be used in glycol based break fluids, provided previous successful tests passed. EPDM | FDA corresponds to foodgrade standards.
Resistance EPDM Elastomers
Good resistance | Average resistance | Low resistance |
|---|---|---|

Application
EPDM can be used for production of U-shaped seals, lip and chevron seals. EPDM is mainly used in cleaning equipment (washing powder, sodium alkali). Moreover, EPDM is the most applicable material for usage in hot water or hot steam (silicone grease lubrication).
Mainly used
- Special parts for cleaning equipment
- Piston and rod seals
- O-rings
- Seals for vehicle break system
