Abstract
A thermal barrier material is disclosed for applications such as heat shields in automobiles and other vehicles. The thermal barrier material is made on a Fordenier paper making machine from a slurry that is very low in organic compounds that can cause smoke and odor when exposed to high temperatures. A first thermal barrier material is disclosed that can withstand up to 650° C. and a second thermal barrier material is disclosed that can withstand up to 1000° C. In each case, the barrier material withstands it max temperature specification while producing extremely low quantities of smoke and extremely low levels of offensive odors. Prior art thermal barrier materials with similar temperature specifications on the other hand produce many times the smoke and offensive odors at the same temperatures and do so for a far longer time.
