The XPS extruded polystyrene foam board (XPS) production line is generally divided into two types: carbon dioxide foam and fluorine foam. Jinweier Company's complete set of carbon dioxide foam XPS extruded board production line is full of carbon dioxide foam. Fully utilizing the "CO2 combination foaming agent" instead of the "fluorine series" foaming agent greatly reduces the production cost of XPS extruded boards, and CO2 as a foaming agent is more environmentally friendly and conducive to sustainable development. The production line of this technology runs quickly and smoothly. The width of the XPS extruded board produced is 600mm-1200mm, and the thickness is in the range of 20-60mm. The average density is 30-45kg/m3, and its homogeneous closed cell foam structure makes the produced board stable, high compressive strength, and low water absorption. The advantage of the XPS extruded board production line using CO2 foaming technology is the use of a two-stage carbon dioxide foaming agent injection system, which ensures accurate and quantitative delivery of carbon dioxide to the extruder system, thereby ensuring the smooth operation of the entire production line. The Jinweier XPS equipment comes in two types: single screw series extruder and co rotating parallel double series screw extruder. The specifications include a series of single screw extruders with a diameter of 135/150 and a series of co rotating parallel double series single screw extruders with a diameter of 75/150. The Jinweier XPS equipment has also produced a series of co rotating parallel double series single screw extruders with a diameter of 95/250. Due to its excellent mixing efficiency, the co rotating parallel double screw extruder can process ingredients composed of multiple components. Sheet metal forming is achieved through vacuum negative pressure forming. With the newly developed vacuum forming unit by Jinweier, the product weight can be reduced while ensuring the quality of the sheet metal, thereby lowering the production cost of the product. Our company is capable of switching between carbon dioxide foaming and Freon foaming with mature technology. It can also be used to retrofit Freon equipment with a carbon dioxide foaming device.

At present, insulation boards on the market mostly use Freon as a foaming agent, which can cause fatal damage to the ozone layer. The environmentally friendly XPS extruded foam insulation board production line developed by Suzhou Jinweier Machinery Co., Ltd. has many advantages such as high automation, fast production speed, and sensitive operation, while the price is lower than similar foreign production lines. The extruded foam insulation board produced by this equipment belongs to green and environmentally friendly building materials. It not only has a long-lasting low thermal conductivity, good dimensional stability, and weather resistance, but also has uniform foaming, fine foam pores, high compressive strength, moisture resistance, non water absorption, easy construction and transportation, and is highly welcomed by users.

XPS extruded polystyrene foam board (XPS) has a good closed cell honeycomb structure and is currently a market insulation material. It uses recycled EPS polystyrene board granulation as the main raw material to complete the product production process of extrusion foaming, shaping, traction and cutting. Its density, water absorption, thermal conductivity and steam permeability coefficient are lower than other types of plate thermal insulation materials, so it has the characteristics of good strength, light weight, impermeable, corrosion resistance, aging resistance, low price, etc., and is widely used in roof thermal insulation systems; Thermal insulation inside and outside the walls of cold storage facilities, barracks, grain depots, and civil buildings; Ground construction aspects such as airport runways and plazas; Civil engineering of highways and railways; In the partition system of buildings such as apartments, office buildings, and factories, etc.
