Fluoro-rubber Compounds


Common Name

FKM, FPM, FFKM

Chemical Name

Fluoro Rubber

General

FKM is a M Class Rubber

  • Contains a saturated chain of the polymethylene type
  • Fluoro rubber of the polymethylene type having substituent fluoro and perfluoroalkyl groups on the polymer chain

Fluorocarbon elastomers are inherently compatible with a broad spectrum of chemicals.? Because of this extensive chemical compatibility, which spans considerable concentration and temperature ranges, fluorocarbons have gained wide acceptance as a material of construction for butterfly valve o-rings and seats.
Excellent resistance to mineral acids, salts solutions, oils and many aliphatic and aromatic hydrocarbons.
Attacked by caustic (sodium hydroxide) and low molecular weight organics.
There are several different grades of material available.? Care should be taken in selecting the right grade for the application.

Application

General

  • Not suitable for steam service
  • Gaskets
  • O-rings
  • Bellows

Sulphuric Acid Plants

  • Seals and gaskets in the gas cleaning system handling weak sulphuric acid.
  • Plate heat exchanger gaskets

 

1.Properties:

  • Outstanding H-temperature resistance.
  • Excellent resistance to fuel,oil,acid and chemicals.
  • Good resistance to gas penetration and radiation.
  • Besides,with all the properties of general rubber.
  • Outstanding physical,electrical and mechanical properties.
  • Can work in harsh,thermal,chemical,and UV environments where general rubber can not .

2.Applications:

  • Extensively used in aerospace/aviation,automobile,petroleum and chemical,mechanical industry,and construction,communication and concrete industry,etc.
  • Mainly used as sealents resisting H-temperature,fuel,oil,etc.,and as erosion-protection material,to make O-ring ,oil,etc., diaphragm,gaskets,rubber bowl and valve core,etc..
