Silicone Sponge Rubber Gasketing

Silicone Sponge Rubber is designed for a variety of gasketing, cushioning, insulating and protecting applications, expanded silicone sponge rubber solutions include formulations designed for general gasketing, flame retardant cushions, solvent resistant gaskets, weather seals and to meet specification grades. Closed cell formulations make them ideal for a variety of gasketing, cushioning, insulating and protective applications over a wide temperature and environmental range. Silicone sponge rubber not only provides thermal stability, excellent compression set resistance, ozone and UV resistance, flame retardance and solvent resistance, but also lowers the material outgassing for cleaner operation due to the most extreme post-cure cycle process in the industry.

Current Trends and Challenges in Silicone Sponge Rubber Gasketing

Silicone sponge rubber gasketing is constantly evolving to meet the changing needs of different industries like electronics, aerospace, automotive, manufacturing, and LED lighting. Here are some current trends and technologies related to silicone sponge rubber gasketing:

Features & Benefits

  • Temperature resistant

Silicone sponge rubber provides excellent performance over a wide temperature range, from -73°C to + 260°C (-100°F to + 500°F)

  • Flame retardant

New UL 94 V-0 flame retardant versions and thermally conductive grade products are available to improve safety for heat and cold transfer, fire and smoke blocking applications and oven seals

  • Strong protection

Superior mechanical properties including formulations designed for general gasketing and dimensional stability result in lasting and reliable protection even in higher strength applications

  • Flexible product offering

Available in a range of firmness values (including soft, medium and firm grades) with fiberglass supported options for additional dimensional stability, and special grades for high temperature and solvent resistance

  • Weather resistant

Closed cell sponge structure forms durable dust, moisture and weather tight seal and is ozone and UV resistant, making this product ideal for both indoor and outdoor gasketing applications

  • Simplified processibility

Silicone sponge rubbers can be supplied with either silicone or acrylic pressure-sensitive adhesive for ease of application, and are post-cured for low outgassing and clean gasketing and sealing
