Firstly acquainted with this material, I was struck by his multifunctionality. Foamed polyurethane is used in various processes associated with industrial activities and construction activities. Let's consider all the advantages and disadvantages of the use of polyurethane, as well as learn areas of use of this material.
Foamed polyurethane
Properties and Material Production
Foamed polyurethane for construction work
In the production of polyurethane foam, two main components are used, which is from izita and polyol. Due to various additives and catalysts, the finished material of different types is obtained. The stabilizer, which is added to the composition, protects the polymers from the negative impact of ultraviolet rays, heat or various contaminants.
Since foamed polyurethane is a very popular substitute for many materials of natural origin, plastics and rubber, let's look at its main advantages:
- The proportion, due to which the possibility of arranging the facade system appears. In addition, transportation and installation are quite simple, thanks to light weight
- Due to the resistance to various external phenomena, polyurethane is used in exterior decoration and indoors with high humidity
- In addition to high strength, which prevails in front of plastic and other types of rubber, the foamed element has the properties of restoring its form
- Working point of use is from -70 to +120 degrees
- Not afraid of various chemicals, oils and therefore the use of an unfavorable environment is allowed.
- Even under conditions of long-term use in rooms with high humidity, mold and fungal disputes do not appear on the material.
If the manufacture of foamed polyurethane occurs a pure form, then it gets white. However, for ease of use, the required number of different pigments that give the material the desired color is added.

Good properties that are inherent in foamed polyurethane allow you to use it for various purposes. Let's consider the most sought-after:
- Varieties of leatherette and shoe sole
- Upholstered furniture and its separate details
- Internal covering of automotive salons - buttons, pedals, torpedo, seats
- Noise absorbing partitions and various polyurethane products
- Inscriptions, stucco, elements of the facade decor and systems
- The possibility of using a sprayed material allows thermal insulation in hard-to-reach places, that is, where the usual insulation does not work out. These places can be complex arched structures, partitions and places with a large cluster of pipelines
- In the premises of industrial and household exploitation, as a waterproofing layer of walls, floors and ceiling
- Anti-billion gaskets, as well as depreciable inserts for machinery and technological equipment
This is not the entire list of areas of activity in which the foamed polystyrene can be applied. I wrote only the most common and well-known options that are used not only in home construction and finishing processes, but also in the conditions of industry.
Comparison of various insulation

For clarity, I decided to make several tables that visually told b about the benefits of self-use as a heater. In the first table we compare the technical indicators of polyurethane foam and mineral wool:
| Required indicator | unit of measurement | Name of the material used | |
| Polyurene Foolder | Minvata. | ||
| Thermal conductivity | W / m to | 0.033 | 0.049. |
| Density | Kg / m3. | 60-80 | 55-150 |
| Compressive strength | MPa | 0,3. | Not normalized |
| Motionable material | In percents | 10% | Low moisture resistance |
| Duration of use | 40 years | 10 years | |
| Specific damage | Damage per year / 100 km | 3-4 | 30-40 |
Already only from that table it becomes clear that polyurethane is a very good thermal insulator, which is distinguished by strength and resistance to moisture. However, let's see how environmentally and safe material in comparison with other well-known insulation:

Tips when spraying polyurethane do it yourself
Foamed polyurethane
If you use a spraying method for good heat insulation, then adhere to some simple usage rules:
- It is best to apply in several layers, so you will achieve the best indicators. The first layer should be 1-2 cm in thickness, if you have minor unevenness, then the second layer compensates for all flaws
- The main factor is the choice of PPU and its brand, the density of the material depends on it after it is frozen
- All warning work can be held year-round, but producing outdoor processes it is better to choose the weather suitable for work.
Other products and decor
Noise insulation of foamed polyurethane
Decorative elements from polyurethane is another proof of the durability of the material. The facade decor produced by PPU will decorate not only the interior inside the house, but the outdoor finish of your housing. If you want to create a classic facade, but at the same time do not spend a large number of financial funds for finishing, then the decor of polyurethane is exactly what you need.
Important! The first houses decorated with the decor from polyurethane appeared in the 70s. It is worth noting that the data of the facades are "alive" to this day.
It was the decor from polyurethane who has proven itself, as a steady and inexpensive material that is distinguished against the background of deficiencies among other elements. To date, the decor can be used for finishing in style:
- Ampir
- Modern
- Classic
- Neoclassicism
- Classicism

Polyurethane products are so diverse that you and you will not immediately choose the appropriate design element. At the moment, among the existing, there are:
- Bas reliefs
- Cornis
- Moldings
- Columns
- Pilastres
- Brackets
- Rusta
- Window sills
- Frames for windows windows
Foamed polyurethane for noise insulation
Another interesting area of use of this material can be safely called the production of eaves. Eaves and polyurethane This is a kind of flexible eaves, in which the radius of bend can have 8 cm. The versatility of such eaves itself speaks for itself, because these products can be fixed both on the wall and on the ceiling using special brackets.
The special flexibility of polyurethane products allows:
- Bending the cornice before getting the necessary form
- Perform a large radius of curvature
- In the process of mounting the cornice, you can adjust the bend
- Re-edit
- In addition to simplicity in the installation you will get a slick of the curtain
- Simple product adjustment by dipping or extension
- Can be used in various interior solutions, as well as for arched openings
- Transportation of a polyurethane profile will not be a problem, since when transporting it is simply folded into the ring
As you can see polyurethane is a fairly popular material and at the same time its demand is fully explained, since the indicators of strength, environmental safety and resistance to chemical impacts on height.
