Description
High Temperature, Sulphur-Free EPDM with Superior UV & Ageing Resistance
Peroxide Cured EPDM Rubber Sheet is a premium-grade 65 Duro EPDM rubber, engineered for high-temperature performance, long-term ageing stability, and superior weather resistance.
Unlike standard EPDM, this material is peroxide cured (sulphur-free), providing enhanced resistance to heat, UV, ozone, and chemical degradation, while eliminating surface blooming and ensuring long-term performance.
