Global XPS Extruded Board Status Analysis and Market Prospect Forecast in 2020Global XPS Extruded Board Status Analysis and Market Prospect Forecast in 2020
XPS extruded board is a rigid foamed plastic board made of polystyrene resin plus other raw materials and polymers, heated and mixed while injecting a catalyst, and then extruded and extruded to form. Its scientific name is thermal insulation Using extruded polystyrene foam (referred to as XPS), XPS has a perfect closed-cell honeycomb structure, this structure allows XPS board to have extremely low water absorption (almost no water absorption), low thermal conductivity, high compression resistance, resistance Aging (without aging decomposition phenomenon in normal use).
1. Excellent thermal insulation:
It has the characteristics of high thermal resistance, low linearity, and low expansion ratio. Its closed cell rate 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, relative to 80% of foamed polyurethane The closed-cell rate, the lead is self-evident. Practice has proved that 20mm thick XPS extruded insulation board, its insulation effect is equivalent to 50mm thick expanded polystyrene, 120mm thick cement perlite. Therefore, this material is currently the best choice for building insulation.
2. Excellent high-strength compression resistance:
Due to the special structure of XPS board, its compressive strength is extremely high, and its impact resistance is extremely strong. According to the different models and thickness of XPS, its compressive strength can reach more than 150-700Kpa, can withstand the ground load of various systems, and is widely used in geothermal engineering, Highways, airport runways, square grounds, large cold storages, interior decoration and insulation, etc.
3. High-quality water-repellent and moisture-proof:
Water absorption is an important parameter for measuring insulation materials. The insulation performance of the insulation material will decrease after absorbing water. Under low temperature conditions, the inhaled water easily freezes, destroying the structure of the insulation material, thereby reducing the compression resistance and insulation performance of the board. Because the polystyrene molecular structure itself does not absorb water, the sheet molecular structure is stable and there are no gaps, which solves the problems of water leakage, penetration, frost, condensation and other materials.
4. Light texture and easy to use:
The completely closed-cell foaming chemical structure of XPS board and its honeycomb physical structure make it light and high-strength, easy to cut and transport, and not easy to break 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 properties are extremely stable. It will not degrade due to water absorption and corrosion, and its performance will be reduced. It can still maintain its superior performance in high temperature environments. According to relevant information, the service life of XPS extruded insulation boards produced by major domestic manufacturers is about 60 years, and they can still maintain excellent performance, and they will not decompose or mildew, and there is no volatilization of toxic substances.
6. Product environmental performance:
The environmental protection performance of XPS board mainly depends on the foaming agent. At present, most domestic manufacturers use CO2 as a catalyst, but some manufacturers have always used Freon, which has been tested by relevant national authorities and has stable chemical properties, non-volatile harmful substances, no harm to human bodies, and production raw materials. The use of environmentally friendly materials does not produce any industrial pollution. This product is an environmentally friendly building material.
