Compared with EPS polystyrene foam plastic plate, its strength, heat preservation, water vapor penetration and other properties have greatly improved. It can maintain its thermal insulation and compressive strength completely under water immersion conditions, and is especially suitable for insulation, insulation and moisture protection of buildings. It is one of the cheap construction materials in today's construction industry.
(1) Incomparable insulation performance of extruding panels
The thermal conductivity of the extruded plastic plate is less than or equal to 0.028 w/mk, which is much lower than other thermal insulation materials(engineering usually uses materials with a thermal conductivity of less than 0.25 w/mk as thermal insulation(insulation) materials), so it has high thermal resistance and Low linear expansion rate characteristics. It is commonly used in roof insulation systems, cold storage, insulation inside and outside the wall, and the effect is unparalleled.
(2) Water absorption without moisture
As a perfect thermal insulation material, the water absorption rate is an extremely important technical indicator. High water absorption rate will lead to poor thermal insulation performance. The extruder has a complete closed hole structure, and there is no gap between the front and back sides of the board., so that leakage, The condensation and freezing/thawing cycles, for example, create moisture that can not penetrate and therefore effectively prevent the entry of water molecules, so that the sheet can not be aged, and its insulation layer will lose its role over time, further causing the insulation structure layer to be renovated. The closed hole structure of the XPS plate can effectively prevent the infiltration of water molecules(including water vapor). Even if it is mechanically damaged during construction, the XPS plate can effectively maintain a low water absorption function due to a tight Honeycomb structure. Because it effectively prevents water molecules from infiltrating and is not hydrophilic, aging is almost impossible, and it is almost the same as buildings.
(3) Outstanding and lasting thermal insulation performance
The low thermal conductivity is a requirement for all thermal insulation materials. The XPS board is made from polystyrene(PS). It is known that polystyrene itself is an excellent thermal insulation material, plus extruding production. Closely closed Honeycomb condenser is more effective in preventing heat conduction.
(4) Unexpected pressure resistance
The XPS extruder is a lightweight, high-strength plate with a compressive strength of up to 350 KPa per cubic meter with a density of no more than 40 kg. Use in buildings can obtain good impact resistance.
The excellent compressive performance of the XPS extruding board is almost unchanged even if it is immersed in water. This feature is not found in other thermal insulation materials.
(5) Good flame retardant
Provide ordinary and flame retardant products according to the requirements of users, can fully meet the requirements of factory buildings, stadiums, exhibition centers, etc. for flame retardant properties of thermal insulation products.
(6) High-quality environmentally friendly products
The chemical properties of the XPS extruder are stable, there is no volatilisation of harmful substances, and no decomposition or mildew occurs. It has good corrosion resistance.
In the production process of the XPS extruder board, environmentally friendly raw materials are used, no harmful gases are produced, and the Environmental Protection concept is also reflected in the production process. The solid waste generated can be recycled and used. It is a recyclable environmentally friendly product.
(7) Construction facilitation costs
Due to its light weight, it is easy to handle, easy to cut, no electric saw, and simple to fix. It can be fixed only with iron sheets and wire plastic adhesive polymer mortar, which can greatly reduce the cost of construction.
