EPDM Compounds — Extreme Temperature
An EPDM rubber compound formulated for excellent resistance to ozone, UV and weathering, with stability across a wide thermal range. It is the right solution for parts permanently exposed to outdoor conditions or severe thermal variations, without contact with mineral oils.

Applications
Construction & Outdoor

Steam / Hot Water Installations
Technical parts for systems operating with steam or hot water, without exposure to mineral oils.
Railway & Industrial
Components subject to severe thermal variations, where long-term weathering stability is essential.
Frequently Asked Questions
Why is EPDM suitable for extreme temperatures?
EPDM (ethylene propylene diene monomer) has a saturated polymer backbone, which gives it high thermal stability and excellent resistance to ozone, UV and weathering, typically operating between -50°C and +150°C.
Does EPDM resist mineral oils?
No — EPDM has poor resistance to mineral oils and hydrocarbons. For applications with oil exposure we recommend NBR compounds.
What industrial and railway applications use EPDM?
Seals and profiles exposed to weathering, components for steam or hot water installations, and railway/industrial parts subject to severe thermal variations without contact with mineral oils.
What is the difference between EPDM and the silicone compound?
EPDM offers better mechanical strength (tensile, elongation) at a lower cost, but its maximum thermal range is lower than silicone, which reaches up to about +230°C and is chemically more inert.
