polyurethane sandwich panel
Polyurethane sandwich panels (urethane), like most sandwich panels, can be used in ceilings and walls, and consist of two layers of sheets that cover the core of the sandwich panel. This type of sound insulation and thermal are much better.
The sandwich of your polyurethane panel is divided into two types:
– Polyester base
– Polyether base
The sandwich panel with polyurethane foam is twice as energy efficient than polystyrene in the best sandwich panels in terms of mechanical and thermal properties. The insulator used is a hard polyurethane type, which puts polyurethane in a row of best thermal insulators, so that a sandwich panel with a thickness of 4 cm is equivalent to a brick wall with a thickness of 50 cm.
In the polyurethane sandwich panel, it is possible to change the insulation properties for a variety of applications, for example:
– Creating an anti-corrosion coating
– elastic and rubbery (elastomeric)
– Become hard foam as excellent insulation
Polyurethane, foamed and injected into sandwich panels, is an insulation that resists moisture against heat.
Sandwich panel with polyurethane foam is produced in two types of wall and ceiling. This product not only has sandstone features of polystyrene panel, but also features such as compact high density non-flammable and integrity between sheet and foam assembly.
The change in the insulation properties of this product has been used for various applications. Polyurethane
The resistance of the sandwich panels depends on the type of sheet, the number of dentin and its steps.
This product is used in huts, dairies, sports halls, industrial halls, poultry houses and cold stores.
Polyurethane foam is a lightweight foam that is produced from the combination of polyethylene and isocyanate under special conditions in the presence of a catalyst.
And also, polyurethane is a type of foam that is more porous and can be used as a thermal insulation.
The maximum performance temperature of the polyurethane is 70 to 80 ° C. Polyurethane decomposes above 100 to 110 degrees. Installer
Other features of the sandwich panel:
Significant bearing load pressure, heat insulation against heat and cold, sound insulation, light weight, moisture-proofing, sheet foam adhesion, cost-effectiveness and long life, fire resistance, health and chemical resistance Other features of this product.
Polyurethane insulating sandwich panels: Insulated panels are composite prefabricated building materials. It is made of a rigid core between two metal plates. The rigid core made of polyurethane is known for its excellent thermal insulation properties. Polyurethane is an insulated material for cold buildings and energy buildings.
Comparison between polyurethane and other insulating materials.
Polyurethane is known for its insulating properties. The annual consumption of polyurethane for the use of insulation is about 662 million kilograms. Insulating properties are usually measured by R-Values. R-Value is the relationship between material thickness and heat transfer per unit area. The higher the R value, the better the insulation properties
Advantages of polyurethane sandwich panel:
– Weights are very low and lightweight
– They do not absorb fluids and are waterproof
– They have a long life and a long life
Due to low energy consumption in the production process, the expense drops sharply
– Non-corrosive by insects and resistant to water and fire
– Diverse and customer-friendly sandwich panels
– Easy installation
What is polyurethane foam?
Polyurethane sandwich panel is a lightweight foam that is made from poly-ethylene and iso-cyanate composition in certain conditions and in the presence of a catalyst. Polyurethane is a type of foam that is more porous and therefore has a very good thermal insulation effect.
The maximum performance temperature of the polyurethane is 70 to 80 ° C. Of course, polyurethane does not lose its strength from 100 to 110 grit but decomposes at higher temperatures. Bacteria do not grow in polyurethane and can be used because of high compressive strength in a wide range of daily use.
Polyurethane (PUR and PU) is a polymer that is made up of organic compounds linked to Orhan (kromate). While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.
Polyurethane polymers are traditionally formed and often formed by the reaction of polyethylene with polyethylene di-ethyl or polyisocyanate. Both the ISO and polyols used to produce polyurethane, on average, contain two or more functional groups per molecule.
