G 100

The GT 100 technology portfolio offers rubber compound groups based on three different polymers: FKM, HNBR, and VMQ. It covers already a broad range of temperature and media resistance for your needs with excellent properties:

FKM/FPM: Fluorocarbons are high temperature oil resistant elastomers, capable of providing a very wide chemical compatibility range. There are several different fluorocarbon compounds available. The basis of the different compounds is the incorporation of fluorine into the polymer chain. Fluorocarbons were originally developed as a copolymer of hexafluoropropylene (HFP) and vinylidene fluoride (VDF). Copolymers are the standard type of FKMs showing a good overall performance with fluorine content typically in the range of around 66 weight percent. Terpolymers composed of VDF, HFP, and tetrafluoroethylene (TFE) have a higher fluorine content compared to copolymers (typically between 68 and 69 weight percent fluorine), which results in better chemical and heat resistance. Compression set and low temperature flexibility may be affected negatively.
