.>The insulation board is an extruded polyethylene insulation board. It is a rigid foam made of polyethylene resin as raw material, plus other raw materials and polymers, mixed by heating, injecting a catalyst, and then extruded and molded. Plastic board. Its scientific name is extruded polyethylene foam for thermal insulation (abbreviation). It has a closed-cell honeycomb structure. This structure allows the board to have extremely low water absorption (almost no water absorption), low thermal conductivity, and high pressure resistance. , Anti-aging (almost no aging and decomposition during normal use).

Performance characteristics of the insulation board
Excellent thermal insulation
It has the characteristics of high thermal resistance, low linearity and low expansion ratio. The closed cell ratio of its structure has reached % or more forms a vacuum layer to avoid air flow and heat dissipation to ensure the durability and stability of its thermal insulation performance. Compared with foamed polyurethane, its leading advantage in closed cell rate of % is self-evident. Practice has shown that the insulation effect of thick extruded insulation boards is equivalent to thick foamed polyethylene and thick cement perlite. Therefore, this material is currently the best choice for building insulation.
, Excellent high-strength compressive resistance
Due to the special structure of the board, it has extremely high compressive strength and strong impact resistance. According to different models and thicknesses, its compressive strength reaches ~ or above and can withstand various systems. Ground load is widely used in fields such as geothermal engineering, highways, airport runways, square floors, large cold storages, and vehicle interior decoration insulation.
, high-quality hydrophobic and moisture-proof properties
Water absorption is an important parameter for measuring thermal insulation materials. When the insulation material absorbs water, its insulation performance decreases. At low temperatures, the water sucked in can easily freeze and destroy the structure of the insulation material, thus reducing the pressure resistance and insulation performance of the board. Since the molecular structure of polyethylene itself does not absorb water, the molecular structure of the sheet is stable and has no gaps, which solves the problems of water leakage, penetration, frosting, condensation and other problems of other materials.
, light weight, easy to use
The board's completely closed-cell foaming chemical structure and honeycomb physical structure make it lightweight and high-strength, easy to cut, transport, not easy to break, and easy to install.
, good stability and corrosion resistance
It will not age, decompose, or produce harmful substances during long-term use. Its chemical properties are extremely stable and will not degrade due to water absorption and corrosion, causing its performance to decrease at high temperatures. According to relevant information, the extruded insulation board can still maintain its excellent performance even if it is used for ~ years without decomposition or mildew and no volatile toxic substances.
, product environmental performance
The board has been tested by relevant national departments and has stable chemical properties, non-volatile harmful substances, and is harmless to the human body. The production raw materials use environmentally friendly materials and do not produce any industrial pollution. This product is an environmentally friendly building material.
Scope of application
Building roof insulation, steel structure roof, building wall insulation, building ground moisturizing, square ground, ground frost heave control, central air conditioning ventilation ducts, etc.
