What is HNBR material?

HNBR (Hydrogenated Nitrile Butadiene Rubber), also known as Highly Saturated Nitrile (“HSN”), is special class of nitrile rubber (NBR) that has been hydrogenated to increase saturation of the butadiene segment of the carbon polymer backbone.

What is HNBR 70?

HNBR 70-compound 88625 is a hydrogenated Nitrile compound of standard quality for use in the industry. This compound has good chemical and mechanical properties.

Is HNBR the same as nitrile?

NBR is the shortened form of nitrile rubber. HNBR is the hydrogenated form of nitrile rubber. It is a synthetic copolymer of acrylonitrile and butadiene. HNBR or hydrogenated nitrile rubber is widely used due to its physical strength and retention of properties even after the exposure to heat, oil, and chemicals.

What is the difference between NBR and HNBR?

HNBR has better heat resistance; oxidation resistance; tensile strength and abrasion resistance than standard nitrile (NBR). Also an excellent choice for automotive refrigerant service. Both o-rings and gaskets can be made from Nitrile materials.

What does HNBR mean?

Hydrogenated Nitrile
Hydrogenated Nitrile is normally abbreviated to HNBR and is also known as Highly Saturated Nitrile. A Higher performance solid rubber material than NBR, achieved through adding Hydrogen Atoms to the Butadiene Segments.

Is HNBR fuel resistant?

HNBR o-rings are made from hydrogenated nitrile specifically designed to provide superior temperature and fuel resistance compared to traditional NBR materials. HBNR o-rings also feature excellent abrasion, wear, and compression set resistance, making them a reliable o-ring in a wide range of tough applications.

Are all green O rings HNBR?

HNBR O-Rings are most commonly in Green or Black, are also avaialable in Yellow and red special compounds.

Is Buna the same as HNBR?

HNBR (commonly called Nitrile Rubber or BUNA-N) is a highly saturated, oil-resistant elastomer, manufactured by subjecting the unsaturated bonds in NBR (a widely used, oil- resistant rubber) to a special hydrogenation process.

Are all green O-rings HNBR?

Is Buna N Hnbr?

What are HNBR O rings used for?

HNBR o-rings are preferable for use with petroleum-based oils and fuels, aliphatic hydrocarbons, vegetable oils, silicone oils and greases, ethylene glycol, water and steam (up to 300ºF), and diluted acids, bases, and salt solutions.

Are HNBR O rings oil resistant?

HNBR O-ring has excellent resistance to oils and chemicals Obtained by hydrogenating the nitrile copolymer, the HNBR O-ring fills the gap left between NBR, EPDM and FKM elastomers where high temperature conditions require high tensile strength while maintaining excellent resistance to oils and chemicals.
