Material

VMQ (silicone rubber, vinyl methyl silicone)

  • Operating temperature-60 °C to +200 °C

Best for extreme heat and cold, food contact, ozone and sunlight, in static joints only. Not for fuels, mineral oils, pressurized steam or moving parts.

Chemical resistance
Can be usedDo not use
Extreme temperatures: stays fully elastic from -50 to -60 °C up to +200 °CMoving parts: friction and abrasion wear it away quickly (static use only)
Hot dry air (ovens, drying chambers, heating cabinets)Fuel: petrol, kerosene, diesel (swells quickly and loses its shape)
Ozone, UV, sunlight, weather and oxygen (does not age outdoors)Mineral hydraulic and engine oils, especially with aggressive additives or aromatics
Water (up to +100 °C), alcohols and physiological solutionsSteam under pressure above +120 °C (in a closed volume the silicone breaks down)
Food and drinks (food-grade VMQ meets FDA / BfR requirements; no smell or taste)Silicone oils and greases (they dissolve the silicone ring)
High-viscosity mineral oils without additives, at moderate temperaturesStrong (concentrated) acids and alkalis: sulfuric, nitric, hydrochloric, caustic soda
Salt solutions and diluted detergentsToluene, benzene, trichloroethylene (aromatic and chlorinated solvents)

Static use only: never on piston rods, rotating shafts or any rubbing surface; silicone wears away within hours or days. Never lubricate with silicone spray or grease (silicone dissolves in silicone); use glycerin or soapy water.
