Enhanced versions, reinforced with additives like fumed silica or ceramic fillers, can endure intermittent temperatures above 315°C (600°F) while maintaining physical and mechanical properties.
-
Versatile Applications: Easily die-cut for custom gaskets and seals, providing a robust solution for high-temperature environments.
-
Broad Resistance: Offers excellent resistance to ozone, oxidation, UV light, and a wide range of chemicals, ensuring long-lasting performance in harsh conditions.
-
Customizable Options: Available in thicknesses from 0.010” to 0.500” and widths up to 60”. Choose from various color and catalyst options to meet specific application needs.
Lsan’s high-temperature silicone sheeting outperforms standard silicone, leveraging cutting-edge technology to provide a superior sealing solution for demanding industrial applications.
What is Extreme High Temperature Silicone?
To maximize the performance of this product, ensure it operates in an oxygen-rich environment, as oxygen is essential for maintaining its functionality at extreme temperatures. Without sufficient oxygen, the product may degrade at significantly lower temperatures. Additionally, prolonged use of our high-temperature silicone sheets at their maximum temperature will naturally reduce the product’s lifespan.
For applications requiring high-temperature resistance for short durations, contact us about our EPC (Extra-Post Platinum Cured) silicone rubber, which offers a service life up to 550°F.
