Nbr is also more resistant to water swell and weathering elements. Silicone can reach constant temperatures of 230 c 446 f and up to 270 c 518 f for special high temperature silicone grades. When compared with silicone rubber epdm is significantly inferior with a maximum temperature of 130 c 266 f. That s it that s the list.
