EPDM | CutWise

EPDM (Ethylene-Propylene-Diene Monomer)

Rubber

EPDM is a synthetic rubber known for its excellent weather resistance, flexibility, and durability. The material retains its elastic properties over a wide temperature range and is resistant to ozone, UV radiation, and aging. This makes EPDM highly suitable for applications in construction, automotive, and industrial sectors where long-term exposure to weather is a factor.
Well-known trade names for EPDM include Keltan®, Vistalon®, and Nordel®. These grades are widely used in roofing, seals, and hoses.

Frequently Asked Questions about EPDM

What makes EPDM suitable for outdoor applications?

EPDM resists ozone, UV radiation, and extreme weather, so it retains its properties during long-term outdoor exposure.

Is EPDM suitable for drinking water contact?

Yes—certain EPDM grades are certified for potable water use, depending on formulation and certification.

How does EPDM perform at low temperatures?

EPDM remains flexible and elastic down to –40 °C, making it ideal for cold environments.

Is EPDM resistant to chemicals?

EPDM has good resistance to many acids, alkalis, and ketones, but is less suitable for applications with oils and hydrocarbons.

Can EPDM be laser cut or milled?

Yes—EPDM can be both laser-cut and milled, depending on the required precision and application.

How does EPDM compare to other rubbers like NBR or SBR?

EPDM offers superior weather resistance and flexibility, while NBR is better for oil resistance and SBR is chosen for general-purpose uses.

Is EPDM recyclable?

Yes—EPDM is recyclable and increasingly reused in various applications, contributing to sustainability.

Can EPDM be bonded?

Yes—EPDM can be bonded with suitable adhesives, although mechanical fastening may be preferred in some cases.
