1.FKM RUBBER PRODUCT DESCRIPTION:

FKM rubber, also known as Fluorocarbon Rubber or Fluorinated Elastomer, is a high-performance synthetic elastomer characterized by the presence of fluorine atoms in its polymer chain. Here's a detailed product description of FKM rubber:

Chemical Composition
-Monomers Common monomers used in the manufacture of FKM rubber include vinylidene fluoride (VDF), hexafluoropropylene (HFP), and tetrafluoroethylene (TFE). Different combinations of these monomers lead to various subtypes of FKM rubber5.

Key Properties

1.Heat Resistance: FKM rubber exhibits excellent heat resistance, with some grades able to withstand temperatures up to 250°C for short periods and 250°C continuously.
2.Chemical Stability: It is highly resistant to a wide range of chemicals, solvents, oils, and fuels, making it suitable for use in harsh environments.
3.Weatherability: Good resistance to ozone, ultraviolet radiation, and weathering ensures long-term durability.
4.Mechanical Properties: FKM rubber has good tensile strength, elongation, and tear resistance.
5.Electrical Insulation: It has good electrical insulation properties, making it suitable for electrical and electronic applications.
6.Gas Impermeability: FKM rubber has low gas permeability, making it suitable for high vacuum applications.

Applications

-Aerospace: Used in fuel systems, seals, and gaskets due to its heat and chemical resistance.
-Automotive: Widely used in fuel hoses, O-rings, seals, and gaskets, as well as in engine compartments due to its resistance to oil, fuels, and heat.
-Chemical Processing: Utilized in pumps, valves, and piping systems to handle corrosive chemicals.
-Oil and Gas: Employed in seals and gaskets in drilling equipment, pipelines, and refinery processes.
-Other Industries: Also used in electronics, medical devices, and various machinery requiring high-performance elastomers.

Processing and Curing

-Processing: FKM rubber can be processed using techniques such as extrusion, injection molding, and compression molding.
-Curing: Common curing methods include peroxide curing, amine curing, and bisphenol curing. The choice of curing method affects the final properties of the rubber.
