Fluorosilicone natural rubber (FVMQ)

FVMQ O-ring

FVMQ O-rings from COG

Apart from the typical properties of normal silicone natural rubber fluorosilicone natural rubber displays superior resistance to oils, fuels and solvents. This applies above all to aromatic and chlorinated hydrocarbons and alcohols. Applications include where resistance over a wide range of temperatures, from -60 °C to +200 °C and in the presence of aggressive media, e.g. petrol, alcohol mixtures, aromatic and naphthenic oils and a range of chlorinated solvents, is required.
