EPT stands for Ethylene Propylene diene Terpolymer.

ETP is the co-polymer of ethylene, propylene and diene

EPT is also called EPDM by reference to Ethylene Propylene Diene Monomer


The primary synthetic rubbers include nitrile, isoprene, styrene-butadiene, butyl, chloroprene, polysulfide, silicone, urethane and ethylene propylene diene terpolymer (ETP) or Ethylene Propylene Diene Monomer (EPDM)

The synthetics rubbers are called indistinctly ETP or EPDM 

EPT is a synthetic rubber known for its superior ability to cope with various climatic conditions, and its resistance to ozone, heat and coldness.

It also performs well as an electric insulator and is known for its chemical resistance.

It has been widely used in automotive parts, electric wires and cables, as well as many other industrial products because of its good resistance to heat/cold, UV rays, and chemicals, in addition to good electric insulation and other superior properties.

For roof covering an EPT membrane is widely use because of its high elasticity and tensile strength. excellent resistance to U.V. and ozone, its flexibility at low temperature (-45°C), its resistance to temperature shocks up to 250°C and alkali rains.
