Our rubber products are a proprietary blend of various polymers formulated to meet stated physicals and specifications. Ozone except pvc blends ketones esters aldehydes chlorinated and nitro hydrocarbons. Buna n properties and uses buna n is a commonly used elastomer.

Although acrylonitrile is a type of cyanide it doesn t break up into ions once dissolved in water which gives the type of cyanide. It exhibits excellent heat resistance abrasion resistance and resistance to petroleum. Nitrile rubber is not toxic. Nitrile is a synthetic rubber elastomers.

Elastomer is natural or synthetic material which does not break when stretched and when released it return to its original length. This rubber is unusual in being resistant to oil fuel and other chemicals. It is used in the nuclear industry to make protective gl. Excellent resistance to petroleum based fluids.

Nitrile butadiene 30 f 250 f. Nitrile nbr rubber material specs exonic polymers is a leading extruder of customer nitrile buna n rubber profiles. Polysiloxane 80 f 420 f. Nbr is used in the automotive and aeronautical industry to make fuel and oil handling hoses seals grommets and self sealing fuel tanks.

Tensile strength tensile range p s i. Buna n is also known as nitrile rubber nbr or perbunan it is synthetic rubber copolymer of acrylonitrile acn and butadiene. Trade names include perbunan nipol krynac and europrene. Many hydrocarbons fats oils greases hydraulic fluids chemicals.

In this article martin s rubber company explains more about the properties applications pros and cons of this versatile rubber material. Nitrile buna n or nbr rubber is a widely used elastomer thanks in large part to its highly oil fuel resistant properties and tensile strength. Nitrile also known as buna n or nbr nitrile butadiene rubber is a type of synthetic rubber polymer. The properties and characteristics of manufactured rubber products may vary based on polymer type and formulation.

Buna n nitrile nbr astm d 2000 classification.
