Common Names: Silicone, VMQ, PVMQ
Trade Name: Silastic®, Elastosil®, Thermoflex®
The term silicone covers a large group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. Silicones are excellent seal materials for extreme temperature in static applications. Outstanding flex and fatigue life, very good for ozone and UV radiation, insulating properties, and physiologically neutral. Silicones can be synthesized with a wide variety of properties and compositions.
- Can be compounded to meet FDA, USP Class VI, USDA, 3-A and Canada AG
- Excellent heat and compression resistance, excellent flexibility, good electrical insulator
- Excellent resistance to oxygen, ozone and sunlight, animal and vegetable oil and grease
- Resistance to fungal and biological attack
- Not recommended for dynamic application since it has low strength and poor abrasion resistance & high gas permeability
- Concentrated solvents, oils, concentrated acids, diluted sodium hydroxide, hydrocarbon based fuels, aromatic mineral oil
- Aromatic Hydrocarbons (benzene, toluene), aromatic mineral oil, acids and alkalis, Superheated water or steam over 250 F
- -90 to 500° F (-68 to 260° C). Depending on compound and application.
