An extremely dynamic elastomer made from silicon, oxygen and hydrogen. Silicones are renowned for their flexibility and low compression set characteristics over a wide operating temperature range.
Highly adaptable, it can be formulated to meet virtually all industry and environmental demands; Silicone is used in a comprehensive range of industrial and consumer applications.
What is Silicone?
Silicone (polysiloxane) also known as MQ, PMQ, VMQ, PVMQ is a class of fluids, resins, or elastomers based on polymerized siloxanes. Their unique chemical inertness, resistance to water and oxidation, and stability at both high and low temperatures have allowed for an extensive range of products to be manufactured.
Where is Silicone used?
Silicones today are used globally because they combine physical properties not found in other polymers. They have excellent heat stability and are used in environments and applications where organic materials would melt or disintegrate. Many silicones are not affected by the effects of UV aging, weather, moisture, heat, cold, and some chemicals/solvents. Silicones are widley used to stick, bond, or couple things together including other silicone products to a wide range of surfaces.
Features/Benefits Of Silicone
Temperature range – standard grades operate between -60 °C to +200°C, with special grades able to work at +300°C to -116°C.
Elasticity, flexibility – can be compressed, twisted and stretched; they will return to its original form.
Weather resistance – long term resistance to all conditions and UV radiation.
Stability – outstanding performance for temperature extremes and chemical attack.
Resistance to aging – Silicones do not harden, crack, peel, crumble, dry-out or rot like most organic materials.
Dielectric properties – good electrical insulating.
Limitations Of Silicone
Abrasion resistance – Silicones do not perform well against other materials in this area. Natural rubber, Viton® and Polyurethane all posses excellent wear resistance. Materials can be supplied with high strength additives to offer modest resistance.
Chemicals – Conventional silicone is not always suitable in environments where it comes into contact with oils, fuels, and solvents. This can be substituted with Fluorosilicone which is specially designed to resist swelling from a wide range of chemicals.
