FKM material induction
FPM:
(Fluoro Carbon Rubber) The fluorine-containing rubber in the molecule has various types depending on the fluorine content (that is, the monomer structure). The commonly used hexafluoride fluororubber was first marketed by DuPont under the trade name "Viton". High temperature resistance is superior to silicone rubber. It has excellent chemical resistance, most oils and solvents (except ketones and esters), weather resistance and ozone resistance. Cold resistance is poor. The general temperature range is -20. ~250 °C. Specially formulated to withstand temperatures down to -40 °C.
advantage:
· Resistant to heat up to 250 °C
· Ability to resist most oils and solvents, especially all acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils
Disadvantages:
· Not recommended for ketones, low molecular weight esters and mixtures containing nitrates. · Automotive, locomotive, diesel engines and fuel systems.
Scope of application:
· Seals from chemical plants.
Perfluoroelastomer FFPM
(Perfluoroelastomer) Advantages:
· Optimal heat resistance
· Excellent chemical resistance
· Low Outgassing Features
· Excellent anti-Plasma characteristics
Disadvantages:
· Poor temperature resistance
· Higher raw material prices
· High production difficulty
Scope of application:
· Perfluoro series products are widely used in the semiconductor industry and information-related industries. The scope of application includes PVC, CVD and etching processes in thin film processes and various high vacuum sealing processes.
