Foam layer with thermal barrier properties

A foam layer comprising:

• a silicone based matrix component,
• a flame retardant filler component, and
• an insulation filler component,
• wherein the foam layer comprises a thickness of at least about 0.5 mm to and no greater than about 10 mm,
• wherein the foam layer comprises a 25% strain compression rating of at least about 5 kPa and not greater than about 500 kPa, a compression set rating of no greater than 25%, and
• wherein the foam layer comprises a self ignition time of at least about 1 minute when exposed to a hotplate test at 650° C.

A thermal barrier composite comprising a foam layer, wherein the foam layer comprises:

• a silicone based matrix component,
• a flame retardant filler component, and
• an insulation filler component,
• wherein the thermal barrier composite comprises a thickness of at least about 0.5 mm to and no greater than about 10 mm,
• wherein the thermal barrier composite comprises a 25% strain compression rating of at least about 5 kPa and not greater than about 500 kPa, and
• wherein the thermal barrier composite comprises a HBF flammability rating as measured according to ASTM D4986.
