Silicones (VMQ) and Fluorosilicones (FMVQ) are both from the same family of inorganic polymers but have different properties and price factor. The major difference between them is that FMVQ has substantially better resistance to chemicals, fuel and oil but is significantly more expensive.

Both VMQ and FVMQ have an outstanding operating temperature range not matched by any other elastomer.

They have wide use in the automotive industry in components such as turbo charger hose, connector boots, gaskets and seals in air conditioning systems.

They have extensive use in the pharmaceutical industry in such products as peristaltic pump tubing, drug dispensing systems and medical equipment.

Aerospace with its requirement for wide temperature range polymers has a number of applications in engine and fuel systems.
