Buna N Rubber Vs Neoprene

General purpose synthetic rubbers and.

Buna n rubber vs neoprene. As a sealing option the crucial difference between buna and viton is the temperature range the materials function in. Rubber properties neoprene epdm buna n silicone sbr butyl natural rubber gum rubber hypalon urethane viton fluoroelastomer fluoro silicone hydrogenated. There are many types of synthetic rubber and they are broadly classified into two categories namely. Applications nitrile rubber is recommended for applications that require oil and fuel resistance abrasion resistance and temperature resistance up to 280 f.

Welcome to our rubber chemical resistance chart. The demand for synthetic rubbers over natural rubber has increased very rapidly over the recent past. In mobile equipment and military vehicles nitrile seals or gaskets are used in carburetor diaphragms fuel systems and hydraulic hoses. 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.

Epdm and neoprene are only two of many types of commonly used rubber however. Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f. 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. Nitrile and neoprene are types of synthetic rubber but have different chemical structures.

Chemical structure nitrile is a copolymer it is made up of a mixture of two molecules. Keydifference neoprene vs nitrile rubber many rubber related product manufacturers rely on various types of synthetic rubber due to various reasons. These are butadiene and acrylonitrile. Viton is resistant to many hydrocarbons and is best to use with chemicals in the petroleum industry.

The two rubbers vary in resistance to heat abrasion flame petroleum or weather so are used for different applications. 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. Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. Neoprene also has a low oxidation rate so it is suitable for both indoor and outdoor.

The polymers are chemically treated to enhance polymer branching for a more flexible material.

The key difference between buna n and viton is that buna n is a copolymer of butadiene.
