Nbr vs epdm

EPDM stands for Ethylene Propylene Diene Monomers and it's a type of high density synthetic rubber. It's not as heat resistant as silicone but is able to withstand high temperatures up to 130°C. Because of that it's used as a component within a wide variety of industries including industrial, construction and automotive.EPDM beats SBR in tensile strength and resistance to heat aging and weathering. Nitrile butadiene rubber (NBR): Nitrile is king of elastomers when it comes to oil- and fuel-resistance. One attraction to NBR is its stability in low temperatures, with the ability to survive extreme cold of -30˚C/ -22˚F, which EPDM and Silicone can't match.NBR and EPDM are two types of rubber materials. NBR stands for nitrile butadiene rubber, while EPDM stands for ethylene propylene diene monomer rubber.
