Silicone is specified here for very good compression set resistance across its range, physiological inertness and low toxicity. This material stands up to ozone and UV exposure, weathering, and extreme heat and cold. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where steam above its rated range or hydrocarbon fuels and oils are present.
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. It sees regular use in food and beverage processing, sanitary process lines, and electronics and electrical enclosures.
