XPS extruded polystyrene foam board (XPS for short)

1, with a closed cellular mounted structure, is currently recognised in the market for thermal insulation materials. Recycled EPS polystyrene board granulation as the main raw material die head extrusion foam, shaping, hauling, cutting to complete the product production process, its density, water absorption, thermal conductivity and vapour permeability coefficient are lower than other types of board insulation materials, so it has the characteristics of good strength, lightweight, impermeable, corrosion-resistant, low price, etc. It is widely used in the roofing thermal insulation system; cold storage, barracks, grain storage, and civil construction of the wall inside and outside of the thermal insulation; airport runway, plaza and other ground construction The wall inside and outside of the thermal insulation; airport runways, squares and other ground construction; roads, railways, civil engineering; flats, office buildings, factories and other buildings in the partition system and so on.

2, XPS equipment has a single screw tandem extruder and isotropic flat double tandem screw extruder two kinds of specifications have φ135/φ150 single screw extruder tandem and φ75/φ150 isotropic flat double tandem single screw extruder. Isotropic twin-screw extruder due to high mixing efficiency, can be processed by a variety of ingredients composed of ingredients.

3、The newly-developed vacuum forming unit of GWELL, the sheet moulding is formed by vacuum negative pressure, which can reduce the proportion of the product under the premise of the quality of the sheet, thus reducing the cost of production of the products.
