EPDM: Ethylene Propylene Diene Monomer (or Terpolymer which is simply a product consisting of three distinct monomers). EPDM is classified as a Thermoset material which means it is either fully-cured prior to being installed or that it cures during natural weathering after installation. EPDM roofs are single-ply membranes meaning there is only one ply of roofing material, not multiple plies laminated together.

| Characteristic |
-
excellent resistance to heat, oxidation, ozone and weather aging due to their stable, saturated polymer backbone structure.
-
good electrical resistivity, as well as resistance to polar solvents, such as water, acids, alkalies, phosphate esters and many ketones and alcohols.
-
Amorphous or low crystalline grades have excellent low temperature flexibility with glass transition points of about minus 60 ¡ÆC.
-
Heat aging resistance up to 130¡ÆC can be obtained with properly selected sulfur acceleration systems and heat resistance at 160¡ÆC can be obtained with peroxide cured compounds.
-
Compression set resistance is good, particularly at high temperatures, if sulfur donor or peroxide cure systems are used.
