All about Silicon Foam Tapes

Silicone foams with open cells are used extensively for light water sealing, cushioning, and dust sealing. For outdoor gaskets and wash-down gaskets as well as resilient cushioning pads, closed-cell silicone foam materials can be used.

You can also buy silicon foam tapes online via Avioparts which has had Excellence in Aviation Services since 1993.

The majority of silicone sponges that are commercially available are made from gum-based, polydimethylsiloxane. When a silicone elastomer has been heated cured, it expands. This creates the closed-cell sponge structure.

This tape has been designed to be versatile and easy to use in situations that require long-term performance. It has a long service life, great conformability, and is flexible. It has a low compression set, high adhesion to many substrates.

Silicone Foam is made from liquid silicone rubber that has been platinum-cured. It is highly resistant to ultraviolet light, ozone, and extreme temperatures. Silicone Foam is flexible and resilient in almost any environment. This self-adhering adhesive tape can be used for cushioning, vibration dampening, thermal insulation, gaskets, and cushioning. Use this seal to keep dirt and moisture out of delicate electronics and other items that could be damaged by the elements.
