What are the materials for high temperature resistant O-rings? Part 2 - Fluororubber O-rings
O-rings are commonly used in the sealing of various industrial equipment because of their simplicity and easy installation. With the development of the high-precision equipment industry, the temperature requirements are getting higher and higher, and the demand for high temperature resistant O-rings is also increasing accordingly. The following is a brief introduction to the second type of high temperature resistant O-rings produced by Shanghai Fuzhao - fluororubber O-rings.

Fluororubber high temperature resistant O-rings
(Fluoro Carbon Rubber) Vulcanized rubber with fluorine content in the molecular structure has many types depending on the fluorine component (i.e. single structure). The hexafluorinated fluororubber widely used at this stage was first sold by DuPont under the trade name "Viton". It has better heat resistance than silicone, excellent acid resistance, resistance to most oils and organic solvents (except ketones and lipids), aging resistance and resistance to active oxygen; its cold resistance is relatively poor, and the general application temperature range is -20~250℃. The unique secret recipe can withstand cold to -40℃.
(1) Advantages:
• Heat resistant up to 250 ℃
• Ability to resist most refined oils and organic solvents, especially all alkalis, aliphatic hydrocarbons, fatty hydrocarbons and animal and vegetable oils
(2) Disadvantages:
• Not recommended for use with macrolides, low molecular weight lipids and nitrate-containing mixtures.
• Vehicles, locomotives, diesel engines and fuel systems.
• Seals for chemical companies.
