Materials
Morgan seal Material Includes Nitrile rubber, fluorine rubber, ethylene propylene rubber, neoprene, chloroprene rubber, silicone rubber and so on.
NBR (Nitrile Butadiene Rubber)
Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.
