Buna N Rubber Vs Neoprene

Applications nitrile rubber is recommended for applications that require oil and fuel resistance abrasion resistance and temperature resistance up to 280 f.

Buna n rubber vs neoprene.

Chemical structure nitrile is a copolymer it is made up of a mixture of two molecules. Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. General purpose synthetic rubbers and. If you are looking for an oil resistant rubber neoprene is a good choice and it also has a temperature resistance of up to 200 degrees fahrenheit f.

There are many types of synthetic rubber and they are broadly classified into two categories namely. The polymers are chemically treated to enhance polymer branching for a more flexible material. Rubber properties neoprene epdm buna n silicone sbr butyl natural rubber gum rubber hypalon urethane viton fluoroelastomer fluoro silicone hydrogenated. Neoprene also has a low oxidation rate so it is suitable for both indoor and outdoor.

Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f. As a sealing option the crucial difference between buna and viton is the temperature range the materials function in. Which seal for your application. In mobile equipment and military vehicles nitrile seals or gaskets are used in carburetor diaphragms fuel systems and hydraulic hoses.

Keydifference neoprene vs nitrile rubber many rubber related product manufacturers rely on various types of synthetic rubber due to various reasons. Viton is resistant to many hydrocarbons and is best to use with chemicals in the petroleum industry. Use this rubber chemical resistance chart to make sure that the elastomer or o ring seal you choose will be compatible with the particular environment.

The demand for synthetic rubbers over natural rubber has increased very rapidly over the recent past. Nitrile and neoprene are types of synthetic rubber but have different chemical structures. Viton is the choice over buna for high temperature applications. These are butadiene and acrylonitrile.

Epdm and neoprene are only two of many types of commonly used rubber however. The two rubbers vary in resistance to heat abrasion flame petroleum or weather so are used for different applications. The key difference between buna n and viton is that buna n is a copolymer of butadiene.
