Silicone Foam Applications

Extruded silicone seal & gaskets applided in aircraft


Silicone foam is used in aerospace applications for sealing, insulation, and cushioning due to its lightweight, durability, and resistance to extreme temperatures and pressures.

Extruded silicone seal & gaskets for windows in vehicles


The automotive industry utilizes foam silicone for gaskets, seals, cushioning, and insulation. Its resistance to automotive fluids, vibration dampening capabilities, and ability to withstand extreme temperatures make it ideal for this sector.

Extruded silicone seals used in medical devices to provide shock absorption for sensitive components


The medical sector relies on silicone foam for its biocompatibility, cleanliness, and ability to be sterilized. Its applications include wound care, medical device cushioning, and sealing solutions.

Silicone foam used in construction for thermal insulation


Construction applications benefit greatly from foam silicone’s adaptability and resilience. Its low density makes it an excellent choice for lightweight yet robust sealing materials. The foam’s ability to conform to irregular surfaces and its resistance to weathering and UV light contribute to the longevity of building structures. Additionally, flame-rated foam silicone is often employed to meet stringent fire safety regulations within 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.


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.
