Buna n rubber properties.

Timco rubber can work with your business to design and provide nitrile parts customized for the specific needs of your applications. The properties and characteristics of manufactured rubber products may vary based on polymer type and formulation. It s a copolymer made up of a combination of acrylonitrile and butadiene molecules. This compound has a relatively high acrylo content making it exceptionally resistant to petroleum base oils and hydrocarbon fuels over a temperature range of 40 f to 250 f.

Buna n is also known as nitrile rubber nbr or perbunan it is synthetic rubber copolymer of acrylonitrile acn and butadiene. Nitrile butadiene 30 f 250 f. Nbr is used in the automotive and aeronautical industry to make fuel and oil handling hoses seals grommets and self sealing fuel tanks. What is nitrile rubber.

Nitrile rubber also called nitrile butadiene rubber nbr buna n is a synthetic rubber that provides excellent resistance to petroleum based oils as well as mineral and vegetable oil. Trade names include perbunan nipol krynac and europrene. Nitrile rubber is not toxic. Please note that information presented here is general to nitrile polymer.

Elastomer is natural or synthetic material which does not break when stretched and when released it return to its original length. Mykin s rn00170 nitrile buna n 70 durometer is a general purpose copolymer of butadiene and acrylonitrile. It is used in the nuclear industry to make protective gloves. Nitrile also known as buna n or nbr nitrile butadiene rubber is a type of synthetic rubber polymer.

Buna n o rings also referred to as nbr o rings and nitrile o rings are the most widely used o ring material in the word because of low cost good mechanical performance with resistance to water most basic oils lubricants and some fuels many pneumatic hydraulic systems and the default choice for basic applications. Our rubber products are a proprietary blend of various polymers formulated to meet stated physicals and specifications. Nitrile rubber also known as nbr buna n and acrylonitrile butadiene rubber is a synthetic rubber derived from acrylonitrile and butadiene.

Many hydrocarbons fats oils greases hydraulic fluids chemicals. Polysiloxane 80 f 420 f. Nbr s stability at h. Although acrylonitrile is a type of cyanide it doesn t break up into ions once dissolved in water which gives the type of cyanide used as poison its deadly characteristics.

This rubber is unusual in being resistant to oil fuel and other chemicals. 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. Thermal properties low temperature range 70º f to 0º f minimum for continuous use static 40º f brittle point 70 f to 0º f. Buna n is a commonly used elastomer.
