The company introduces Japanese patent formula new plates developed and produced by vulcanizing machine, pressing machine in high temperature and high pressure working environment; The product is made of imported heat-resistant resin, fiberglass cloth and composite strengthening materials, conquering the difficulty of poorer thermal insulation in higher density and greater pressure. Regardless of compressive strength, thermal insulation performance or service life, it has a much better performance than tradition asbestos (first-level carcinogen) thermal insulation plate.
