XPS extruded board

HNHSJD (XPS)polystyrene extruded insulation board                                          

HNHSJD extruded polystyrene (XPS) insulation board is a hard board made of polystyrene resin as raw material and continuously extruded and foamed through a special process. It has an independent closed bubble structure inside and is a highly resistant material. It is an environmentally friendly thermal insulation material with excellent properties such as pressure resistance, non-absorbent, moisture-proof, airtight, lightweight, corrosion-resistant, long service life and low thermal conductivity.

HNHSJD extruded polystyrene (XPS) insulation boards are widely used in wall insulation, insulation of flat concrete roofs and steel structure roofs, moisture-proof insulation of low-temperature storage floors, parking platforms, airport runways, highways and other fields, and control of ground freezing. It is a high-quality heat-insulating and moisture-proof material.

HNHSJD extruded polystyrene (XPS) B1 grade products use high-quality heat-resistant flame retardants during the production process, and use advanced flame retardant mixing conveyors to evenly transport the flame retardants into the host machine evenly with the main ingredients. Mix thoroughly to solve the problem of uneven distribution of flame retardant.

Wonderful presentation in every detail, quality achievement in every process.

Product performance advantages

Excellent, long-lasting thermal insulation                                               

The thermal conductivity of HNHSJD  extruded board is 0.028w/m·k, which has the characteristics of high thermal resistance and low linear expansion rate. Its thermal conductivity is much lower than other insulation materials, such as EPS board, foamed polyurethane, insulation mortar, cement perlite, etc. At the same time, because this material has a stable chemical structure and physical structure, it ensures the durability and stability of the thermal insulation performance of this material.

Excellent water and moisture resistance                                    

HNHSJD extruded board has a tight closed cell structure. The molecular structure of polystyrene itself does not absorb water, and there are no gaps on the front and back of the board. Therefore, the water absorption rate is extremely low, and it has good moisture-proof and anti-penetration properties.

High quality and environmentally friendly                                                

HNHSJD extruded board will not decompose and mildew, will not volatilize harmful substances, and has stable chemical properties. At the same time, in the production process, advanced CO2 foaming technology is used to replace traditional Freon foaming without damaging the atmospheric ozone layer. Using environmentally friendly raw materials, no harmful gases and no wastewater are generated. The solid scraps formed can be recycled and reused. It is a high-quality environmentally friendly product.

Anti-corrosion, long-lasting durability                                                    

General rigid foam insulation materials are prone to aging after several years of use, resulting in water absorption and performance degradation. HNHSJD  extruded board has excellent anti-corrosion, anti-aging and thermal insulation properties, and can still maintain its excellent performance under high water vapor pressure.

High strength and pressure resistance

Because the foam structure of HNHSJD  extruded board is closely connected and there are no gaps between the walls, its compressive strength is extremely high and remains unchanged even if it is soaked in water for a long time. Therefore, it can withstand good impact resistance when used in parking platforms, airport runways, highways and other fields.

Lightweight and high hardness

The complete closed-cell foam structure of HNHSJD  extruded board forms a lightweight and uniform honeycomb structure, resulting in high hardness, but it is not as brittle as polyurethane foam and phenolic foam, so it is not easy to break. It is not only light to transport and install, but also easy to cut. , it will not affect the bearing capacity of the structure when used as roof insulation.
