Polyurethane insulation is actually a solid and cold foam that is used in many ways in the construction industry. . This insulation is obtained from the combination of 2 materials isocyanate and polyol, which after combining these 2 materials with each other and with time, this solid and cold foam is obtained. Polyurethane foam has high flexibility and can still maintain its properties as a permanent insulation over time. This insulation has a very low heat and cold transfer coefficient and is usually used in roofs and windows. Considering its unique properties, future polyurethane foam will continue to be considered due to its ability to be used in various industries and as an alternative to hard and traditional materials. As technology develops and its production increases, it is expected to find more applications in various industries, including electronics, automotive, and construction industries. Also, efforts to improve the properties of polyurethane foam and produce a new generation of it will continue, and perhaps in the future, polyurethane foam with properties beyond the current properties will be used. For example, efforts are underway to produce polyurethane foam with electronic properties for use in the electronics industry due to its excellent electrical insulation. Usage of polyurethane foam
In the early days of polyurethane thermal insulation production, this foam was used in airplanes. But later, the important application of this insulation in the construction industry was realized and it was used in this way. Today, this material is used in other industries such as pharmaceuticals, petrochemicals, and gas industries. Although today, the use of polyurethane thermal insulation is also used in other cases, such as industrial tanks, and this type of insulation is also used in metal roofs and pipelines. Air ducts and cooling systems are other uses of this foam. It is necessary to know that polyurethane thermal insulation is also used for the production of sandwich panels.
Introducing types of polyurethane insulation
Naturally, polyurethane thermal insulation is different according to the type of use and also the characteristics it should have, so nowadays it is produced in different types and according to the customer's request. But among the most important types of insulation, the following can be mentioned: Spray polyurethane insulation To use this type of insulation, the work surface must first be completely cleaned of any dust. Then the polyurethane mixture is sprayed on the desired surface through a special device. The thickness of this insulation depends on the number of times the foam is sprayed on the surface, but usually it is not more than 5 cm. It is necessary to know that polyurethane spray foam is created in 2 types, open and closed, the open cell type is suitable for sound insulation, and the closed cell type is used as thermal insulation. Injected polyurethane insulation
Special devices are used to create polyurethane injection insulation. In fact, this method is used for smooth and inaccessible surfaces. Tubular and half-tube polyurethane insulation This type of insulation is a suitable option for insulating all types of pipes, so it is produced and used in different sizes according to the size and thickness of the pipe. Polyurethane block and board insulation
This type of foam is used to insulate large tanks and wide walls. The form of block polyurethane thermal insulation is, as the name suggests, in the form of blocks and boards, and to make them, insulating materials are poured into special molds and after cooling, they are cut into different and usable sizes.
