XPS extruded board foaming screw

   XPS extrusion foam molding machine screw based on polystyrene resin as raw materials and other raw materials and inclusion, inject catalyst by cooking at the same time, and then extruded extrusion molding and manufacturing rigid foam plastic board. Its scientific name is adiabatic with extruded polystyrene foam plastic (XPS), XPS with perfect obturator honeycomb structure, this structure makes XPS board has a very low water imbibition (almost no water absorption), low thermal conductivity coefficient, high pressure resistance, aging resistance. Especially in flame retardant effect on corrosion of screw is very big, my company production of XPS. EPS screw barrel inner hole overall alloy. Screw via special corrosion resistant materials processing, increase service life. XPS screw production has been to zhoushan several screw monopoly enterprises, my company to increase r&d strength after several XPS extruded board
