Peroxide Cured Nitrile Rubber

BRP manufactures peroxide cured nitrile rubber suited for long-term severe applications where exposure to heat, oil and compression set is a must.

BRP Peroxide cured nitrile rubber is available in 60 +/- 5 and 65 +/- 5 durometer both having a minimum tensile of 1,700 PSI or more. This material meets the requirements of ASTM D2000. Peroxide-cured compounds are known for their high temperature properties ranging from -35º to 275°F without significant degradation and superior compression set characteristics.

Peroxide cured nitrile rubber is used in a broad range of industrial, automotive, oil field, power transformer, and aircraft fluid applications.

Peroxide cured nitrile rubber is formulated for high temperature resistance in aliphatic hydrocarbons, mineral oils and greases, dilute acids and alcohols at low temperature. This combination of elements can create a recipe for disaster for conventional polymers, however peroxide cured nitrile rubber is formulated to efficiently handle these demanding applications.

Standard nitriles are usually sulfur-cured, but for applications requiring heat resistance, peroxide cured nitrile rubber is the preferred choice. While peroxide cured nitrile rubber is slightly more expensive, it provides superior heat resistance and lower compression sets than its sulfur-cured counterparts. All BRP products are American-made in our Lima, Ohio facility.
