Isolon

Isolon is an insulating material of wide application, which deserves a high appreciation due to its versatility. It is manufactured in accordance with the international ISO standard, therefore it is manufactured for both the local market and for export. The scope of application is quite wide: these are many spheres of industry, industrial sphere, etc. Let's consider in more detail what material is made of, which has the texture, technical characteristics and properties.

Isolon is a flexible polyethylene foam type, it has a cellular structure where each cell is closed. Can be made of different density and thickness - which is another plus to the universality of the material. To get Isolon is not so simple: raw materials undergo a thorough processing( otherwise called deep), so we can say that this insulator is highly technological. Previously, technologies did not reach the current level and, say, 50 years ago, materials of this level were used only in the space and medical fields.

Types of Isolon

Select the following types of isolon( see photo, video). Isolon PPE is essentially a physically crosslinked polyethylene foam( cross-structure), Isolon NPE is extruded( the structure is not cross-linked).It is about the molecular invoices of the material. These are the two most common and applied species, but there are others: PPE-L, PPE-NR, PPE-HX, NPE-L.The main difference is whether the molecular structure is physically or chemically cross-linked. Quite often they use the advice of professional technologists when choosing these materials in order not to make a mistake, as it is quite easy to get confused in such a variety of brands and subspecies.

The markings are usually of the following type, for example: PET 3015, where the first two digits 30 denote the multiplicity of the foaming, and the second two, 15, its thickness in mm.

Technical data of ISOLON

Each of the varieties of Isolon has individual technical characteristics. They are the determining parameter when choosing the most acceptable option.

Crosslinked The isolon has a closed cell structure, therefore its density is higher than that of the NPE.It is 30 - 200 kg / m³.Other characteristics are as follows:

• The value of thermal conductivity is within the range of 0.031-0.032 W / m * K;
• Thickness limits - 1-50 mm;
• The sound absorption values ​​can reach 68%;
• Water absorption - up to 1%;
• Permissible temperature - from -60 ° to + 75 °;
• The average vapor permeability level is approximately 0.001 mg /( m • h • Pa);
• Heat reflective characteristics - reflectance from 95 to 97%;radiation indices - 3 - 5%.

Density Isolon NPE , which has a non-crosslinked cell structure, is lower than that of PES: 19-35 kg / ³.The following technical characteristics are inherent in this version:

• The value of thermal conductivity is 0,040 W / m * K;
• The sound absorption values ​​are in the range of 3-13%;
• Thickness limits - 1-16 mm;
• Water absorption - up to 0,2%;
• Operating temperature - from -80 ° to + 80 °;
• The average vapor permeability level is approximately 0.001 mg /( m • h • Pa).

Both types of material are considered very reliable, can be operated up to 90 years.

Advantages and disadvantages of

It can hardly be called at least one drawback of this material, except that the relatively high cost and the need for careful transportation and storage. It is also important to correctly install insulation - here again, you can damage the external structure.

The advantages are, first of all, high thermal insulation properties. Of course, we are considering other materials of this class. A distinctive feature of Isolon is a low coefficient of thermal conductivity( 0.03 W / m * K and more, depending on the variety and the manufacturer).In addition, this material has good protective properties against moisture, steam. Here we are talking about the so-called waterproofing. Each of the cells is closed - because the water does not absorb the texture, it eventually protects the necessary surface from moisture, steam, misting, etc.

Next, we should mention high shock and sound protection - and this despite the fact that the protective layer is verythin. It also has high dynamic strength;moderately elastic. The specific gravity is small. Let's consider further positive technical characteristics.

Many insulators are not used in some areas because they have high chemical activity;Isolon is practically not active in this respect. It is about the interaction with oil, gasoline, fuel oil, oils and other fuels and lubricants. It is possible to add here many other chemical compounds of flammable or poisonous character, to which Isolon is also neutral.

The material has a long service life - up to 100 years, which is a big plus;reuse is possible. It is possible to summarize such important property as ecological cleanliness, safety - both for the person, animals - and for all nature as a whole;does not have a negative impact on soil, plants.
