Hydrogenated Nitrile Butadiene (HNBR), also known as Highly Saturated Nitrile (HSN) is a special class of nitrile rubber (NBR) .O-rings are the most commonly used elastomers for sealing products .Nitrile, also known as Buna-N or NBR, is a copolymer of Butadiene and Acrylonitirle. It has a temperature range of -40F to +250F and is exceptionally resistant to petroleum base oils and hydrocarbon fuels. Nitrile materials also exhibit excellent tensile strength and abrasion resistance properties.
HNBR can be formulated to meet the application temperatures ranging from -45 ° C to 165 ° C, and HNBR is classified by ASTM as DH-type polymer.
Available for professional use and also suitable for home use.
