Is there a domestic manufacturer of thermal insulation for liquid hydrogen storage tanks

There are. Thermal insulation materials, materials that can block the transfer of heat flow, also known as thermal insulation materials. Traditional insulation materials, such as fiberglass, asbestos, rock wool, silicate, etc., new insulation materials, such as aerogel felt, vacuum panels. There are domestic manufacturers of thermal insulation materials for liquid hydrogen storage tanks, and the thermal insulation materials are divided into three categories: porous materials, heat-reflective materials and vacuum materials. The former use of the material itself contained in the pore thermal insulation, because the air or inert gas inside the void has a very low thermal conductivity, such as foam materials, fiber materials, etc.; heat reflective materials have a very high reflection coefficient.
