XPS Extruded Polystyrene Foam

XPS Extruded Polystyrene

Product introduction:

The full name of XPS (extruded polystyrene) is Extruded Polystyrene Foam Board.

It is a rigid foam board made of polystyrene resin as raw material plus other raw materials and polymers, heated and mixed while injecting the catalyst, and then extruded and molded. Its scientific name is Xps Extruded Polystyrene Foam Insulation Board (XPS for short). XPS has a perfect closed-cell honeycomb structure. This structure allows XPS boards to have extremely low water absorption (almost no water absorption), low thermal conductivity, high compression resistance, and aging resistance ( There is almost no aging decomposition phenomenon under normal use).

Yu Ou Nuo Xps Insulation Sheet is used for building roof insulation, steel structure roof, building wall insulation, building ground moisture, square ground, ground frost heave control, central air conditioning ventilation pipe, airport runway insulation layer, high-speed railway subgrade, etc.

Application scope of extruded board:

building roof insulation, steel structure roof, building wall insulation, building ground moisture, square ground, ground frost heave control, central air conditioning ventilation pipe, airport runway insulation layer, high-speed railway subgrade, etc.

Performance advantages of extruded board:

1. Excellent thermal insulation

It has the characteristics of high thermal resistance, low linearity and low expansion ratio. The closed cell rate of its structure reaches more than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, and ensuring the durability and stability of its thermal insulation performance. Compared with 80% closed cell rate of foamed polyurethane, its advantages are obvious. Practice has proved that the insulation effect of 20 mm thick XPS extruded insulation board is equivalent to 50 mm thick expanded polystyrene and 120 mm thick cement perlite. Therefore, this material is a good choice for building insulation at present.

2. Excellent high strength and compression resistance

Due to the special structure of Xps Foam Board Heat Insulation, its compressive strength is very high and its impact resistance is very strong. According to the different types and thickness of XPS, its compressive strength can reach 150-500kpa or more, and it can bear the ground load of various systems. It is widely used in geothermal engineering, motorway, airport runway, square ground, large cold storage, decoration and thermal insulation in the cars and other fields.

3. High quality hydrophobicity and moisture-proof

Water absorption is an important parameter to measure thermal insulation materials. After absorbing water, the thermal insulation performance of the insulation material decreases. At low temperature, the inhaled water is easy to freeze, which destroys the structure of the insulation material, thus reducing the compression resistance and thermal insulation performance of the plate. Because the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable and there is no gap, it solves the problems of water leakage, penetration, frosting and condensation of other materials.

4. Light and easy to use

The chemical structure of the full closed cell foaming and its honeycomb physical structure of XPS board make it light and high-strength, easy to cut and transport, and not easy to damage, and easy to install.

5. Good stability and corrosion resistance

In long-term use, it does not age, decompose, or produce harmful substances. Its chemical properties are extremely stable, and it will not be degraded due to water absorption and corrosion, and its performance will not be reduced. It can still maintain its superior performance in high temperature environments.

6. Product environmental performance

XPS board has been tested by the relevant national departments. It has stable chemical properties, no volatilization of harmful substances and no harm to human body.The production raw materials adopt environmentally friendly materials and do not produce any industrial pollution. This product is an environmentally friendly building material.
