Shanghai thermal insulation extruded board Huamei extruded board wholesale price

Polystyrene foam is divided into two types: expansion type and continuous extrusion type. Compared with boards, boards are the third generation of rigid foam insulation materials. Technically, they overcome the complicated production process of boards and have advantages that boards cannot replace. Superior performance. It is a plate made of polystyrene resin and other additives through an extrusion process with a continuous and uniform surface layer and a closed-cell honeycomb structure. These thick plates with a honeycomb structure have no gaps at all. This closed-cell structure of thermal insulation The material can have different pressures (-) while having the same low value of thermal conductivity (only ./.) and long-lasting excellent insulation and compression properties, with a compressive strength of up to -. / Thermal insulation board is an extruded polystyrene insulation board. It is made of polystyrene resin as raw material plus other raw materials and polymers. It is heated and mixed through a special process while injecting a catalyst, and then continuously extruded and extruded. Rigid foam plastic board manufactured. Its scientific name is extruded polystyrene foam for thermal insulation (abbreviation). It has a perfect closed-cell honeycomb structure. This structure allows the board to have extremely low water absorption (almost no water absorption). It is an energy-saving and environmentally friendly insulation material with excellent properties such as moisture-proof, airtight, lightweight, corrosion-resistant, low thermal conductivity, high pressure resistance, anti-aging (almost no aging and decomposition during normal use), long service life, and low thermal conductivity. /Extruded board (sheet)/ Its mechanical properties are unmatched, and in addition, it has a tight closed-cell structure due to continuous extrusion. Its density, water absorption, thermal conductivity and steam permeability are lower than other types of boards, and it is currently a recognized thermal insulation material in the market. /Edit/, 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 above, forming a vacuum layer to avoid air flow and heat dissipation, ensuring the durability and durability of its thermal insulation performance. Stable, compared to the closed cell ratio of foamed polyurethane, its leading advantage is self-evident. Practice has proven that the insulation effect of thick extruded insulation boards is equivalent to thick foamed polystyrene 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, its compressive strength is extremely high and impact resistance is extremely strong. Depending on the different models and thicknesses, its compressive strength reaches ~ or above, and it can withstand the ground load of various systems. It is widely used in fields such as geothermal engineering, highways, airport runways, square floors, large cold storages, and vehicle interior decoration insulation. / Extruded polystyrene board/High-quality hydrophobicity, moisture resistance/water absorption is an important parameter for measuring thermal insulation materials. After the insulation material absorbs water, its thermal insulation performance decreases. At low temperatures, the absorbed water easily freezes, destroying the structure of the insulation material, thereby reducing the pressure resistance and thermal insulation performance of the board. Since the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable and has no gaps, which solves the problems of water leakage, penetration, frosting, condensation and other problems of other materials. /, Lightweight, easy to use / The completely closed-cell foaming chemical structure and honeycomb physical structure of the board make it lightweight and high-strength, easy to cut and transport, not easy to be damaged, and easy to install. /, Good stability and anti-corrosion properties / In long-term use, it will not age, decompose, or produce harmful substances. Its chemical properties are extremely stable and will not degrade due to water absorption and corrosion, causing its performance to decline. In high-temperature environments It can still maintain its excellent performance even under severe conditions. According to relevant information, even if it is used for 3 to 3 years, the extruded insulation board can still maintain its excellent performance without decomposition or mildew, and there is no volatilization of toxic substances. /, Product environmental performance / The board has been tested by relevant national departments and has stable chemical properties, does not volatilize harmful substances, and is harmless to the human body. The production raw materials are environmentally friendly materials and do not produce any industrial pollution. This product is an environmentally friendly building material. /Edit/Building roof insulation, steel structure roof, building wall insulation, building ground moisturizing, square ground, ground frost heave control, central air conditioning ventilation ducts, airport runway insulation layer, high-speed railway subgrade, etc./Sales phone number 3 Manager Wang
