One of the more interesting silicone foam parts Stockwell has made was a thermal insulating jacket for an electronic device. The material used was HT-800 silicone foam, the foam’s cellular structure gives the material insulating properties. HT800 is a UL94 V0 flame rated foam and also has electrically insulating properties.

The part shown below was constructed from standard “off the shelf” thicknesses of HT-800, though a few thicker layers required laminating. A variety of shapes were waterjet cut and hand assembled.

Stockwell has a dedicated Production Cell for Assembly where silicone foam, silicone sponge, urethane foam and EMI materials are bonded, lamininated and/or assembled.
