The XPS extruded polystyrene foam board production line uses polystyrene and a foaming agent as raw materials, which are formed into an insulating board through high-temperature extrusion. Currently, the main foaming agent used in the industry is hydrochlorofluorocarbon (HCFC), which has a relatively high potential for ozone layer depletion. According to the Montreal Protocol, China has been gradually restricting the use of HCFCs. Shandong Tongjia Machinery Co., Ltd., based on market trends, has introduced advanced technology and tailor-made R&D to develop CO2 extruded board equipment that completely replaces HCFC foaming agents with CO2, truly achieving a fluorine-free foaming process and pioneering the use of CO2 foaming.
