NBR has a better oil resistant compared with EPDM, but EPDM has a good wear resistance, aging resistant and heat-resisting. EPDM is usually made into water pipe.NBR is an  unsaturated carbon rubber,  which is polymer made from acrylonitrile and butadiene. The acrylonitrile amount from low to high, and oil resistant will enhance and cold resistance will decline during the producing.The main feature of NBR is oil resistance. Good resistant and tolerant to petroleum base and non-polar solvent, however, not good resistant to polar oil and polar solvent ood antistatic property Bad Ozone resistanceNBR can be consistence with PVC, POM and nylon, and could made into polymer materialsCommon NBR temperature:-20~120, low-temperature resistant NBR can work in -50 environment.EPR is made from the ethylene and propylene, which have two types: EPM and EPDMozone aging resistance Weather aging resistance heat resistance The above property is the best one in commonly used rubber. EPDM Still has the othe
