With a perfect closed-cell honeycomb structure, is currently recognized as the market insulation materials. The main raw material is recycled EPS polystyrene plate granulated material, which is extruded, foamed, shaped, pulled and cut by the die to complete the product production process, its density, water absorption, thermal conductivity and steam permeability are all lower than other types of plate-like thermal insulation materials, so it has the characteristics of good strength, light weight, impermeability, corrosion resistance, anti-aging, low price, etc. , widely used in roof thermal insulation system, cold storage, barracks, grain depot and civil buildings inside and outside the wall thermal insulation; airport runway, Plaza and other ground construction; highway, Railway Civil Engineering; Apartment, office, factory buildings and other buildings in the partition system, and so on.

XPS equipment has two kinds of single screw series extruder and co-rotating double series single screw extruder, the specifications are: Single Screw Extruder series type and Φ75/Φ150 co-rotating double series single screw extruder. The co-rotating twin-screw extruder can process the ingredients which are composed of many components because of its excellent mixing efficiency.

Using CO2 to replace Freon and Butane to produce XPS extruded board, the CO2 foaming unit newly developed by Jinwei Company is environment-friendly and low-cost.
