Silicone rubber (VMQ and FMVQ) is a highly versatile elastomer that can be used in many diverse sectors. Industrial grades of silicone rubber are generally based on polydimethylsiloxanes, partially substituted with other organic groups such as alkyl, vinyl or phenyl, which regulate respectively the processability, reticulation and resistance to low temperatures. In the special case of fluoro-silicone rubber, one of the two methyl groups is substituted by a trifluoropropyl group. This unique feature results in a better resistance to fuels, solvents and to non-polar oils, as well as in an improvement of the compound performance at low temperatures. The incorporation of reinforcing fillers – typically precipitated or amorphous-ventilated silica – yields the formulations the hardness and the mechanical properties suitable for a static or dynamic application.
