As a material, Silicone is valued for excellent electrical insulating properties, physiological inertness and low toxicity. Expect good resistance to many oxidizing chemicals, ozone and UV exposure, and extreme heat and cold. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to hydrocarbon fuels and oils or concentrated acids will shorten service life.

This item meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in ovens and heated equipment, pharmaceutical manufacturing, and medical devices.
