Inflaming-retarding heat-insulating compound sandwich panel
A technology for flame retardant thermal insulation and sandwich panels, which is applied in synthetic resin layered products, layered products, glass/slag layered products, etc., which can solve the problems of limited application, unsatisfactory flame retardant performance, and poor flame retardant performance of composite panels. It can improve the effect of low impact strength, excellent thermal insulation performance, and excellent heat resistance.
