A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Ethylene propylene diene monomer (CAS 25038-36-2) is a synthetic terpolymer rubber of ethylene, propylene, and a non-conjugated diene, supplied in primary (bale or pellet) form. Its saturated polymer backbone gives strong resistance to weather, ozone, heat, and water, making it a standard elastomer for outdoor and sealing applications such as roofing membranes, automotive weatherseals, gaskets, hoses, and wire and cable insulation.
Frequently Asked Questions
What is ethylene propylene diene monomer (EPDM) material?
EPDM (CAS 25038-36-2) is a synthetic terpolymer rubber made from ethylene, propylene, and a non-conjugated diene, supplied in primary bale or pellet form. Its saturated backbone gives strong resistance to weather, ozone, heat, and water, so it is widely used for roofing membranes, automotive weatherseals, gaskets, hoses, and wire and cable insulation.
Is EPDM actually rubber?
Yes. EPDM is a true synthetic elastomer (terpolymer rubber), not a plastic. It is classified under HS 4002.70 as ethylene-propylene-non-conjugated diene rubber.
Does acetone dissolve EPDM?
EPDM is a non-polar elastomer and generally resists polar solvents such as acetone, water, and dilute acids/bases. It is more susceptible to swelling in non-polar hydrocarbons and oils. Confirm chemical compatibility for your specific service conditions and compound grade before use.
What forms is EPDM supplied in for manufacturing?
EPDM is supplied in primary polymer form — typically bales or pellets — for compounding and downstream conversion into membranes, profiles, gaskets, hoses, and cable jacketing. RawSource supplies industrial quantities with CoA.
What is the cost of bulk EPDM?
Pricing depends on grade, form (bale or pellet), volume, and delivery location. RawSource supplies EPDM in bulk — request a quote with your target volume and grade requirements for current delivered pricing.
