As a material, Silicone delivers an exceptionally wide service temperature range and very good compression set resistance across its range. Expect good resistance to many oxidizing chemicals, weathering, and dry heat. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). It should not be specified for service in concentrated acids or abrasive dynamic service.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across pharmaceutical manufacturing, medical devices, and electronics and electrical enclosures.
