Coruba offers a variety of rubber sheeting in different grades, one of which is EPR rubber (Ethylene Propylene Rubber)
EPR is a similar compound to EPDM. However, they differ in the creation processes and in some of their applications. EPR is vulcanised using a peroxide-based cure system, whereas EPDM can use peroxide or sulphur-based systems. This is due to the third monomer, Diene, found in EPDMs.
EPR has good resistance to weather and ozone. As well as moderate resistance to acid and strong bases.
