Buna N Rubber Vs Neoprene

Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f.

Buna n rubber vs neoprene.

General purpose synthetic rubbers and. Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. Chemical structure nitrile is a copolymer it is made up of a mixture of two molecules. Epdm and neoprene are only two of many types of commonly used rubber however.

In mobile equipment and military vehicles nitrile seals or gaskets are used in carburetor diaphragms fuel systems and hydraulic hoses. 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. 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. There are many types of synthetic rubber and they are broadly classified into two categories namely.

The two rubbers vary in resistance to heat abrasion flame petroleum or weather so are used for different applications. 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. As a sealing option the crucial difference between buna and viton is the temperature range the materials function in. The polymers are chemically treated to enhance polymer branching for a more flexible material.

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. Which seal for your application. The demand for synthetic rubbers over natural rubber has increased very rapidly over the recent past. Neoprene also has a low oxidation rate so it is suitable for both indoor and outdoor.

Welcome to our rubber chemical resistance chart. Nitrile and neoprene are types of synthetic rubber but have different chemical structures. Keydifference neoprene vs nitrile rubber many rubber related product manufacturers rely on various types of synthetic rubber due to various reasons. Applications nitrile rubber is recommended for applications that require oil and fuel resistance abrasion resistance and temperature resistance up to 280 f.

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. The key difference between buna n and viton is that buna n is a copolymer of butadiene. Viton is the choice over buna for high temperature applications.
