Blue NBR Water Resistance Water Seal Ring for Home Appliance SealsNitrile rubber, also known as Buna-N, Perbunan, or NBR, is a synthetic rubber copolymer of acrylonitrile(ACN) and butadiene. Nitrile butadiene rubber (NBR) is typically resistant to oil, fuel, and other chemicals- it is more resistant than natural rubber to oils and acids but has lesser strength and flexibility. It can be attached by ozone, aromatic hydrocarbons, ketones, esters, and aldehydes.
Buna/ Nitrile Rubber
NBR's capability to endure a range of temperatures from -40ºC to +108ºC makes it a perfect material for aeronautical applications. Other uses of nitrile rubber include non-latex gloves for the healthcare trade, automotive transmission belts, fuel and oil handling hoses, grommets, O-rings, gaskets, oil seals, V-belts, synthetic leather, printer's roller, and as cable jacketing.
