It resists ozone and UV exposure, weathering, and dry heat. That behavior comes from the compound itself: Silicone is known for very good compression set resistance across its range and flexibility that holds at very low temperatures. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving steam above its rated range or abrasive dynamic service call for a different compound.

It sees regular use in food and beverage processing, ovens and heated equipment, and medical devices.
