gather benzene ethylene Foam plastic It is divided into expandable EPS and continuous extrusion XPS board Compared with XPS board, XPS board is the third generation of hard foam insulation material. Technically, it overcomes the complicated production process of EPS board and has superior performance that EPS board cannot replace. It is made of polystyrene Vinyl resin And other additives produced by extrusion process with continuous uniform surface layer and closed cell honeycomb structure. These thick plates of honeycomb structure, completely free of voids, can have different pressures (150-500Kpa) and have the same low thermal conductivity (only 0.028W/M.K) as well as excellent thermal insulation and compression resistance, The compressive strength can reach 220-500Kpa.
1. Excellent thermal insulation
It has the characteristics of high thermal resistance, low linearity, and low expansion ratio. Its structure has a closed cell rate of more than 99%, forming a vacuum layer to avoid air flow and heat dissipation, and ensure its good and stable thermal insulation performance. Compared with the 80% closed cell rate of foaming polyurethane, it has obvious advantages. Practice has proved that the thermal insulation effect of 20mm thick XPS extruded insulation board is equivalent to 50mm thick foamed polystyrene and 120mm thick cement perlite. Therefore, this material is the preferred choice for building insulation at present.
2. Superior high degree compression resistance
Due to the special structure of XPS board, its compressive strength is high and its impact resistance is strong. According to the different models and thicknesses of XPS board, its compressive strength reaches more than 150~500Kpa, and can withstand the ground load of various systems. It is widely used in geothermal engineering, expressway, airport runway, square ground, large cold storage, interior decoration and thermal insulation and other fields.
3. High quality hydrophobicity and moisture resistance
Water absorption is an important parameter to measure thermal insulation materials. The insulation performance of the insulation material decreases after water absorption. At low temperatures, the water inhaled is easy to freeze, which destroys the structure of the insulation material, thus reducing the compression resistance and insulation performance of the plate. Because the polystyrene molecular structure itself does not absorb water, the plate molecular structure is stable, and there is no gap, which solves the problems of water leakage, penetration, frosting, condensation and other problems of other materials.
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. Good stability and corrosion resistance
During long-term use, it does not age, decompose or produce harmful substances. Its chemical performance is more stable than it does. It will not degrade due to water absorption and corrosion, which will reduce its performance. It can still maintain its superior performance under high temperature environment. According to relevant information, XPS extruded insulation board can still maintain good performance even if it has been used for 30-40 years, without decomposition or mildew, and without volatilization of toxic substances.
6. Product environmental performance
XPS board has been tested by relevant national departments to have stable chemical performance, no volatile harmful substances, and harmless to human body. The raw materials used for production are environment-friendly materials, without any industrial pollution. This product is an environment-friendly building material.
