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.

The demand for synthetic rubbers over natural rubber has increased very rapidly over the recent past. Rubber properties neoprene epdm buna n silicone sbr butyl natural rubber gum rubber hypalon urethane viton fluoroelastomer fluoro silicone hydrogenated. 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. Which seal for your application.

Chemical structure nitrile is a copolymer it is made up of a mixture of two molecules. 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. Epdm and neoprene are only two of many types of commonly used rubber however. Neoprene or polychloroprene is a synthetic rubber made up of polymers of chloroprene molecules through a process of free radical polymerization and various chemical reactions.

General purpose synthetic rubbers and. To learn more about other rubbers including butyl nitrile and silicone rubber check out our buying guide on the commonly used types of rubber in industry. In mobile equipment and military vehicles nitrile seals or gaskets are used in carburetor diaphragms fuel systems and hydraulic hoses. The key difference between buna n and viton is that buna n is a copolymer of butadiene.

The two rubbers vary in resistance to heat abrasion flame petroleum or weather so are used for different applications. Viton is the choice over buna for high temperature applications. As a sealing option the crucial difference between buna and viton is the temperature range the materials function in. There are many types of synthetic rubber and they are broadly classified into two categories namely.

Nitrile and neoprene are types of synthetic rubber but have different chemical structures. The polymers are chemically treated to enhance polymer branching for a more flexible material. Keydifference neoprene vs nitrile rubber many rubber related product manufacturers rely on various types of synthetic rubber due to various reasons. Key difference buna n vs viton buna n and viton are commercial names for butadiene acrylonitrile nitrile rubber and vinylidene fluoride hexafluoropropylene copolymer respectively both these elastomers are widely used synthetic elastomers that possess a unique set of physical and chemical properties.

Welcome to our rubber chemical resistance chart. Neoprene also has a low oxidation rate so it is suitable for both indoor and outdoor. Viton is resistant to many hydrocarbons and is best to use with chemicals in the petroleum industry.
