Nitrile Rubber Material Properties

Rubber or thermoset elastomer tse material notes.

Nitrile rubber material properties. 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 in this article martin s rubber company explains more about the properties applications pros and cons of this versatile rubber material. Mykin s rn00170 nitrile buna n 70 durometer is a general purpose copolymer of butadiene and acrylonitrile. Material properties nitrile offers excellent oil and solvent resistance across a wide temperature range. A material made for oil resistance.

Nitrile rubber nbr acrylonitrile butadiene rubber categories. Unlike natural rubber and other materials nitrile rubber is more resistant to heat aging. Nitrile rubbers are copolymers of butadiene and acrylonitrile. Rubber material selection guide nbr nitrile or buna n acrylonitrile butadiene abbreviation nbr astm d 2000 classification bf bg bk chemical definition acrylonitrile butadiene 30000 series physical mechanical properties durometer or hardness range 20 95 shore a tensile strength range 200 3 500 psi.

Acrylonitrile content may range from 18 50. Or better yet use the rubber chart to find which material will best suit your environment. The amount of oil resistance in nitrile rubber depends on the percentage of acrylonitrile. This is due to nitrile s compatibility with most environments as well as it s relative cost compared to other rubber materials.

For example if you need to find rubber compression properties rubber weather. This rubber materials comparison chart gives you key factors in your choice of rubber mechanical properties. This synthetic elastomer has very good resistance to engine oil and gasoline very good resistance to alkalis and acids and superior resistance to petroleum based hydraulic fluids. The term has also been applied to copolymers of other dienes and or nitriles.

It exhibits excellent heat resistance abrasion resistance and resistance to petroleum. With a proven ability to withstand lubricants solvents oil water and hydraulic fluids nitrile is recommended for use in environments with crude oil gasoline propane petroleum oils and water. Trade names include perbunan nipol krynac and europrene this rubber is unusual in being resistant to oil fuel and other chemicals. Nitrile is the most commonly used rubber material.

Nitrile rubber is a synthetic rubber copolymer of acrylonitrile acn and butadiene that you may know better. Nitrile is a synthetic rubber elastomers. This feature is a key advantage as it allows nitrile to not harden and lose its damping capability as quickly as natural rubber and other solutions. Nitrile rubber is most popular for its oil resistance although it s also tough and temperature resistant.

Nitrile rubber also known as nbr buna n and acrylonitrile butadiene rubber is a synthetic rubber derived from acrylonitrile acn and butadiene.
