As a new type of composite thermal insulation material, thermal insulation board has the characteristics of high heat resistance temperature, slow heat conduction, high toughness, high pressure resistance and not easy to deform, high flatness and easy processing. It is generally used in rubber and plastic molds, mechanical equipment, machines, and as a thermal insulation component, which can play the role of insulation, heat preservation, heat insulation, and rust prevention. The synthetic stone has high strength, relatively hard, relatively poor thermal insulation function and fast heat transfer, and the material has no toughness and is not easy to process. It will be misled into thinking that synthetic stone is a heat insulation board, so the most important thing is to figure out what the purpose of using the heat insulation board is, what effect you want to achieve, whether to require heat insulation or to find a jig tool for auxiliary production .
