Fluorine rubber Introduction: FPM (Fluoro Carbon Rubber) of intramolecular fluorine-containing rubber, according to the fluorine content (ie monomer structure) and there are various types. Six series of fluorinated Viton currently the most widely used first by DuPont to "Viton" tradename listed. High temperature resistance than silicone rubber, has excellent chemical resistance, resistance to most oils and solvents (ketones, esters except), weather resistance and ozone resistance; cold is relatively poor, the general temperature range of -40 ~ 240 ℃. Advantages: high temperature corrosion resistance, chemical resistance to ozone aging tolerance is very low permeability can wear heat to 240 ℃ for most oil and solvents have the ability to resist, especially all of the acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils, hydraulic oil, fuel, lubricants, inorganic acids. Disadvantages: Not recommended suitable for ketones, ethers, ketones, certain amine compounds and high-temperature water and hydrogen fluoride, and a mixture of low molecular weight lipids containing nitrate cars, locomotives, diesel engines and fuel systems Scope: Chemical Plant seals, are widely used in the automotive, electronics, aerospace, shipbuilding, and so requires relatively high precision, high temperature, high wear resistance, the harsh conditions of the work environment, with industrial development, fluorine rubber material is also continuous improvement and innovation, The following is a Viton material properties and apply a wide range of uses.
