NBR black 80Sh rolls
excellent oil resistance, chemical resistance & aging resistance (long-lived)
The NBR rubber (also called Perbunan) consists of acrylonitrile and butadiene, is a copolymer and is a rubber compound for many oil-resistant sealing applications. The rubber is characterized by excellent oil resistance, abrasion resistance and tensile strength, as well as a favorable aging behavior and a low compression set. The resistance to oils, fats (vegetable and animal), fuels and heating oils is excellent.
The hard rubber compound has a hardness of about 80°Shore A and has a high intrinsic stability and a low bending behavior. Compared to the standard hardness (like car tires) of approx. 65°Shore A, this rubber compound is a little harder and stays very stable in shape over a large area of pressure and does not noticeably spring. The natural vibration of the rubber is very low under load.
