Materials technology: EPDM [ethylene propylene]
Ethylene propylene has outstanding heat, ozone and weather resistance and excellent electrical insulating properties; it offers:
- excellent weather and ozone resistance
- high tensile strength
- resistant to non-flammable hydraulic fluids (Skydrol) but poor resistance to mineral oils.
