For a long time, polyurethane foam is considered one of the most popular building materials. The enormous variety in the application of this unique material allows it to be used not only as a heater in the construction of buildings, but also in the production of fabrics and furniture.
Polyurethane foam is synthetic foam in the form of a rectangular canvas, which has a different thickness and is easy to use. In fact, polyurethane foam can be described as a kind of plastic. In 1937, German scientists led by chemist invented the PPU. At that time, the material was not yet so popular however, it was clear that it has unique properties and that many possibilities await it for further use in production. This was the first option for Spray Foam Insulation.
Nowadays, polyurethane foam is very popular. The production of polyurethane foam is a feasible task. This is easy to do right on site, so it is sufficient to respect the necessary proportions of special ingredients. The seams are made by pouring the components of petrochemical processing into a special form. After a complete mixing, the mixture is distributed in molds prepared with a press, where the material hardens and assumes the required shape and dimensions.
According to its structure, the material is obtained porous, with the presence of cells that are filled with gaseous substance. Cell sizes affect the density of the material.
Depending on the type of stiffness, there are different types of polyurethane foam:
- Standard version.
- Hard material.
- More rigid polyurethane foam.
- Highly elastic.
- Elastic, not combustible.
The flame-resistant insulation brand has high thermal insulation properties. Its technical characteristics make it an indispensable material for the organization of buildings and industrial companies. This material is used in production areas with a high degree of responsibility, such as the automotive industry and aviation.
Hard foil polyurethane foam has proven effective in wall insulation. This material is produced in the form of slabs and has anti-noise properties. The installation of the walls in the building is done both from the outside and from the inside. Rigid polyurethane foam is excellent for insulating pipes. Often special shapes are used, attached to the tube with clamps or wire, which, in turn, help maintain heat and protect them from damage and low air temperatures.
Polyurethane foam is a modern building material, which has a solid structure and thermal insulation properties. The purpose of polyurethane foam is quite varied and includes many industries, such as building construction, aviation, automotive industry, toy production and upholstered furniture.
The main positive aspects of the material can be identified as follows:
- The material does not cause allergic reactions.
- Does not form mushrooms and molds.
- Resistant to temperature changes.
- Convenient in work.
- Wide range of activities.
- High sound insulation performance.
Polyurethane foam is a non-combustible material. Higher temperatures will not cause a fire, but the insulation may start to burn. This process can be stopped by cooling the material. Therefore, when the surface can begin to heat up, it is better to abandon the use of polyurethane foam.
