Introduction to xps extruded board:
It is based on gathering benzene Vinyl resin Add for raw materials other Raw materials, excipients and polymers of , which is made by heating, mixing and injecting catalyst, and then extruding Foam plastic board Its scientific name is extruded polystyrene foam for thermal insulation (XPS for short). XPS has an intact closed cell honeycomb structure, which makes XPS board have extremely low water absorption (almost no water absorption), low thermal conductivity, high compression resistance, and slow aging (almost no aging decomposition phenomenon in normal use).

Xuzhou extruded board Performance characteristics:
1. Excellent thermal insulation
It has the characteristics of high thermal resistance, low linearity and low expansion ratio, and its closed porosity reaches More than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, ensuring good and stable thermal insulation performance, compared with foaming polyurethane 80% of the closed pore rate, the advantages are self-evident. Practice has proved that 20mm thick XPS extruded insulation board Its thermal insulation is equivalent to 50mm thick foamed polystyrene, 120mm thick cement perlite. Therefore, this material is used for building thermal insulation Better choice 。
2. Superior high degree compression resistance
because XPS Extrusion molding plate The special structure of The compressive strength of XPS with different models and thicknesses can reach 150~700Kpa or more, and can withstand the ground load of various systems. It is widely used in geothermal engineering, highways, airport runways, square floors, large refrigerators, interior decoration and thermal insulation and other fields.

3. High quality hydrophobicity and moisture resistance
Xps extruded board Water absorption is an important parameter to measure thermal insulation materials. After absorbing water, the insulation performance of the insulation material decreases. At low temperatures, the water sucked in is easy to freeze, which destroys the structure of the insulation material, thus reducing the compression resistance and insulation performance of the plate. Since the polystyrene molecular structure itself does not absorb water, the plate molecular structure is stable without gaps, improvement Other materials have problems such as water leakage, penetration, frosting, condensation, etc.
4. Light texture, easy to use
The completely closed cell foaming chemical structure and cellular physical structure of XPS board make it light and high, easy to cut, transport, not easy to damage, and easy to install.

5、 Product environmental performance
XPS Flame retardant extrusion plate The environmental protection performance mainly depends on the foaming agent, which is currently used by most domestic manufacturers CO2 is used as the catalyst, but some manufacturers have been using Freon. According to the detection of the relevant national departments, the chemical performance is stable, no volatile harmful substances, harmless to human health, and the production raw materials are environment-friendly materials, without any industrial pollution. This product is an environment-friendly building material.
Scope of application: building roof insulation, steel structure roof, building wall insulation, building ground moisture, square ground, ground frost heave control, central air conditioning ventilation pipeline, airport runway insulation layer, high-speed * * * subgrade, etc.
