Problems solved by technology

[0002] Polystyrene foam board, also known as foam board and EPS board, is a white object formed by heating and pre-expanding the foamable polystyrene beads containing volatile liquid foaming agent in the mold. The structural characteristics of holes are mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and carving, etc.; however, traditional polystyrene foam materials Due to the foamed micropores in the middle, it is easy to cause low compressive strength and poor shock absorption effect
