Hydrogenated Nitrile is the product of the hydrogenation of Nitrile, resulting in varying degrees of saturation of the polymeric chain, along with a range of enhanced physical strength and chemical resistance properties.
Hydrogenated Nitrile also known as saturated Nitrile, is obtained by introducing Hydrogen into the Nitrile to saturate the hydrocarbon chains in the rubber. It has better wear and extrusion resistance than NBR and has good chemical compatibility.
Key Uses: All oil resistant applications, including exposure to such oil additives as detergents, anti-oxidants and anti-wear agents. Exposure to oil soured with metal sludge. Seals for oil well applications. Seals for automotive fuel handling systems. Seals for general industrial usage.
HNBR is widely used in automotive and oil industries and maintains excellent resistance to motor oils, sour gas, amine/oil mixtures, oxidized fuels, and lubricating oils. HNBR is resistant to mineral oil-based hydraulic fluids, animal and vegetable fats, diesel fuel, ozone, sour gas, dilute acids and bases. It also resists new bio-oils (biological oils). It is suitable for high dynamic loads and has a good abrasion resistance.
