Carboxylated Nitrile Butadiene Rubber

Highly saturated nitrile hsn temperature range.

Carboxylated nitrile butadiene rubber.

Available hardness range shore a 50 95. For assistance in identifying the appropriate polymer or material or to develop and formulate a xnbr or carboxylated nitirle rubber compound to meet your specific application and performance requirements please contact rahco rubber inc. Hydrogenated acrylonitrile butadiene rubber 22 f 300 f. The result is a major resistance to swelling and abrasion as well as higher tensile and breaking strengh.

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. Nychem n4000m carboxylated nitrile butadiene latex. Nychem n4000m one of our specialty emulsion offerings. Trade names include perbunan nipol krynac and europrene this rubber is unusual in being resistant to oil fuel and other chemicals.

Nitrile rubber also known as nbr buna n and acrylonitrile butadiene rubber is a synthetic rubber derived from acrylonitrile acn and butadiene. Carboxylated nitrile butadiene rubber xnbr hydrogenated nitrile butadiene rubber hnbr or. Carboxylated nitrile xnbr carboxylated nitrile xnbr is a special type of nitrile polymer that exhibits enhanced tear and abrasion resistance. Produced by adding a carboxylic acid group to a nitrile rubber this material contains more cross linking points than the common nbr.

For this reason xnbr based materials are often specified for dynamic applications such as rod seals and rod wipers. Whereas the oil and solvent resistance properties of the rubber will retain at the excellent. Upper continuous service temp. Contrary to that the resistance to water the.

Decreased elasticity at low temperatures with hydrogenation over standard nitrile. Between 54 c and 135 c. Tensile strength up to. Excellent heat and oil resistance improved fuel and ozone resistance approximately 5x over nitrile good abrasion resistance.

Nbr is used in the automotive and aeronautical industry to make fuel and oil handling hoses seals grommets. Heat resistance up to 100 c 212 f with shorter life 121 c 250 f. Buna n between 40 c and 135 c low temperature between 65 c and 120 c.
