RUBBER: EPDM
EPDM is an ethylene propylene diene rubber. It has good tensile strength and breaking strength. However, it is not resistant to petroleum products or concentrated acids.
Advantages of EPDM rubber:
- Very good resistance to: bad weather, heat, cold,
- Ozone, aging,
- Acids, polar solvents (water, ketones, alcohols, glycols).
- Electrical insulation
- Limits: Poor resistance to fuels, chlorinated, aromatic or aliphatic solvents, petroleum derivatives and oils.
- fire resistance.
- Flame spread is low.
Example of EPDM applications:
- Window seal
- Tires
- Playground floors
- Geomembranes
Sectors of use of EPDM:
- Automotive
- Industry
