Carboxylated nitrile butadiene rubber xnbr hydrogenated nitrile butadiene rubber hnbr or.
Carboxylated nitrile butadiene rubber.
Excellent heat and oil resistance improved fuel and ozone resistance approximately 5x over nitrile good abrasion resistance.
Nitrile rubber also known as nbr buna n and acrylonitrile butadiene rubber is a synthetic rubber derived from acrylonitrile acn and butadiene.
The result is a major resistance to swelling and abrasion as well as higher tensile and breaking strengh.
Nbr is used in the automotive and aeronautical industry to make fuel and oil handling hoses seals grommets.
Produced by adding a carboxylic acid group to a nitrile rubber this material contains more cross linking points than the common nbr.
Decreased elasticity at low temperatures with hydrogenation over standard nitrile.
For this reason xnbr based materials are often specified for dynamic applications such as rod seals and rod wipers.
Xnbr carboxylated nitrile butadiene rubber.
Carboxylated nitrile butadiene rubber xnbr is a special type of nitrile butadiene rubber nbr containing carboxyl functional groups which cause to exhibit enhanced tear and abrasion resistance 7.
Introducing carboxylic acid groups to the polymer backbone of nbr nitrile butadiene rubber significantly alters the rubber s properties extra crosslinks in the polymer creating a polymer matrix with significantly increased strength tear modulus and abrasion resistance at the expense of reduced compression set water resistance resilience and some low temperature properties.
