Buna N Rubber Vs Neoprene

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

Buna n rubber vs neoprene.

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. The demand for synthetic rubbers over natural rubber has increased very rapidly over the recent past. There are many types of synthetic rubber and they are broadly classified into two categories namely. As a sealing option the crucial difference between buna and viton is the temperature range the materials function in.

Welcome to our rubber chemical resistance chart. Viton is resistant to many hydrocarbons and is best to use with chemicals in the petroleum industry. Epdm and neoprene are only two of many types of commonly used rubber however. 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.

These are butadiene and acrylonitrile. Neoprene also has a low oxidation rate so it is suitable for both indoor and outdoor. 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.

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. General purpose synthetic rubbers and. The polymers are chemically treated to enhance polymer branching for a more flexible material. 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. Rubber properties neoprene epdm buna n silicone sbr butyl natural rubber gum rubber hypalon urethane viton fluoroelastomer fluoro silicone hydrogenated. Viton is the choice over buna for high temperature applications. 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.
