Abstract:
A thermal barrier material for use in shielding components of a vehicle from hot exhaust surfaces includes 35 to 53% of a plurality of clays by weight and a remainder including magnesium silicate, alumina trihydrate, alumino-borosilicate glass, rock wool, basalt fiber, acrylamide copolymer coagulant, acrylic latex, fatty alcohol alkoxylate, or anionic polyacrylamide. A sample of the thermal barrier material, when exposed to a temperature of 400° Celsius, produces smoke having a density less than 5 g/cm3 as measured according to the ISO 5659-2:2006(E) standard.
