Silicone rubber can withstand a wider range of temperature extremes than nearly all other elastomers, remaining viable from -80°F to +450°F. Silicone has excellent temperature range and good compression set. Silicone can withstand many extreme environments and is inherently a fungus resistant material. It can resist water and many chemicals, including some acids, oxidizing chemicals and ammonia.
Silicone Rubber is ideal for high and low-temperature applications.Electrical properties are excellent and resistance to weathering and ozone attack is outstanding. It is not resistant to super-heated steam. Physical properties are generally low but are at least retained at higher temperatures. Gas permeability is very poor as is resistance to petroleum-based fluids. Silicone rubbers are expensive in comparison to most other rubbers. Food Quality/FDA compliant grades are available for use in the food and pharmaceutical industries.
