Insulation materials generally refer to materials with a heat coefficient less than or equal to 0.12. Thermal insulation materials have developed rapidly, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. For every ton of mineral wool insulation used in buildings, one ton of oil can be saved a year. Insulation materials Industrial equipment and pipe insulation, the use of thermal insulation measures and material aerogel was first applied to the United States National Space Administration developed space suit insulation lining. It has the characteristics of low thermal conductivity, low density, high flexibility, fireproof and waterproof.
