Silicone Foam & Sponge Types
Tenchy offers two primary forms of closed-cell silicone foam, or silicone sponge:
- Silicone foam sheets, pads & rolls: Available in various thicknesses and densities, these versatile sheets are ideal for gaskets, seals, cushioning, thermal insulation, sound dampening, and electrical insulation applications in HVAC systems, electronic enclosures or medical devices.
- Silicone sponge cords, gaskets, strips, tubes, blocks & more: Specifically designed for precise sealing and insulation in challenging environments, these different shapes are commonly used for electronic equipment seals, water sealing, cushioning, flame retardancy, sound and vibration insulation, oven seals, and food processing machinery.
Highly Effective Sealing
Silicone foam creates airtight seals to block out moisture, dust, and contaminants while its compressible nature allows it to adhere perfectly to irregular surfaces – perfect for gaskets and seals in applications ranging from automotive components and electronic enclosures.
Design Versatility
Foam silicone’s versatility as a material makes it suitable for custom seals, gaskets and components in industries ranging from aerospace to medical. It can easily be formed into various shapes and sizes for complex designs – perfect for sealing devices, gaskets and components for custom seals or gaskets that suit a range of uses such as aerospace or medical.

Silicone Foam Applications
Aerospace
Silicone foam is used in aerospace applications for sealing, insulation, and cushioning like aircraft cabin sealants or protecting critical components from high pressure environments due to its lightweight, durability, and resistance to extreme temperatures and pressures.
Automotive
Silicone foam has become an indispensable element of automotive production, from gaskets and seals to vibration dampening and insulation. Thanks to its resistance to automotive fluids, vibration dampening capabilities and extreme temperature resistance properties, silicone foam excels at meeting all these criteria for automotive production.
Medical
Silicone foam/sponge has become increasingly important to medical applications due to its biocompatibility, sterilizability, and cleanliness. Applications range from wound care and device cushioning cushioning sealing solutions – to wound care wound treatment solutions and food-grade applications compliant with FDA regulations (21 CFR 177) for food contact applications. Our food grade silicone foams comply with these FDA requirements ensuring safe food contact use applications.
Construction
Silicone foam’s adaptability and resilience make it an excellent choice for construction applications, from lightweight yet robust sealants to irregular surface conformance and weathering resistance – not to mention UV degradation resistance – all make for long lasting building structures. Furthermore, flameproof (UL 94 V-0 compliant) silicone foam fulfills stringent fire safety regulations in the construction industry.
More Information
Silicone foam is an advanced material made from rubberised foam with a porous structure. This unique composition results in a lightweight, flexible foam with various beneficial properties. Notable for its versatility, foam silicone can be crafted into various forms, including silicone foam sheets, silicone foam strips, and custom shapes to suit diverse applications. Its inherent characteristics make it ideal for sealing, cushioning, and insulating purposes across multiple industries.
FAQs
1. What is the flammability rating of Tenchy’s silicone foam?
Our silicone foam meets the UL 94 V-0 standard for flame retardancy.
2. Can Tenchy manufacture silicone foam in custom shapes and sizes?
Yes, we can create custom silicone foam products to your specifications.
3. Is Tenchy’s silicone foam suitable for food contact applications?
Yes, we offer food-grade silicone foam that meets the requirements of 21 CFR 177.
4. What is the difference between closed-cell and open-cell silicone foam?
Closed cell silicone foam has a structure where air is trapped within the cells, providing better insulation and compression set properties. Open-cell silicone foam has interconnected cells, making it more breathable and flexible.
5. Why use silicone foam?
Silicone foam or sponge is chosen for its unique combination of properties, including excellent temperature resistance, flexibility, compression set resistance, sealing ability, and biocompatibility. These characteristics make it ideal for demanding applications requiring durability, safety, and reliable performance in harsh environments.
6. What are the differences between silicone and polyurethane foams?
Silicone offers superior temperature resistance, chemical resistance and compression set compared to polyurethane foams. Silicone also tends to be more biocompatible for use in medical and food contact applications than its polyurethane counterpart; polyurethane typically costs less and provides higher tensile strength than silicone options.
7. Silicone sponge vs regular sponge: What are its key differences?
Silicone sponge stands out as being more resistant to heat, chemicals and UV radiation than traditional materials such as cellulose or synthetics; furthermore it has better compression set characteristics and longer durability making it suitable for demanding applications where regular sponges might degrade over time or fail completely.
