SILICONE

Silicone: Silicone rubber (Q) is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from -80°F to +550°F while still maintaining its useful properties. Because of these properties and its ease of manufacturing and shaping, silicone rubber can be found in a wide variety of products. Silicone can withstand several extreme environments and is inherently a fungus resistant material. Resistant to water and many chemicals, including some acids, oxidizing chemicals and ammonia.
