Buna N Rubber Vs Neoprene

Viton is the choice over buna for high temperature applications.

Buna n rubber vs neoprene.

The demand for synthetic rubbers over natural rubber has increased very rapidly over the recent past. Keydifference neoprene vs nitrile rubber many rubber related product manufacturers rely on various types of synthetic rubber due to various reasons. In mobile equipment and military vehicles nitrile seals or gaskets are used in carburetor diaphragms fuel systems and hydraulic hoses. 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. There are many types of synthetic rubber and they are broadly classified into two categories namely. The key difference between buna n and viton is that buna n is a copolymer of butadiene. Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f.

Epdm and neoprene are only two of many types of commonly used rubber however. Neoprene also has a low oxidation rate so it is suitable for both indoor and outdoor. Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. General purpose synthetic rubbers and.

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. Applications nitrile rubber is recommended for applications that require oil and fuel resistance abrasion resistance and temperature resistance up to 280 f. The polymers are chemically treated to enhance polymer branching for a more flexible material.

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. These are butadiene and acrylonitrile. Viton is resistant to many hydrocarbons and is best to use with chemicals in the petroleum industry.
