What is polyethylene foam sheet? | Complete introduction to polyethylene foam board
Sheet polyethylene foam, also known as board polyethylene foam, is a combination of polyethylene and air bubbles. Polyethylene was first made in England during the polymerization process of ethylene gas, and then after combining with air and trapping air bubbles inside, polyethylene foam was created.
The combination of air bubbles in polyethylene creates a very high cell tracking property. This feature has made polyethylene foam one of the best insulation materials, so that this product has wide applications in industry, construction and sports clubs.
Polyethylene foam has different types such as sheet, roll, tube, crossling, metallized and adhesive polyethylene foam. Since the flexibility of this material is high, it can be designed and produced in any way.
Characteristics of laminated polyethylene foam
This product, which is also called polyfoam, is soft and highly flexible. In this way, it does not break easily against environmental pressures and can be used in curved places. There are no toxic or illegal substances in its structure, and it does not release any substance even during work, and it is considered one of the safe compounds.
Laminated polyethylene foam is heat, cold, electricity, moisture, water and dust insulating. Therefore, it can be used in wet or wet environments without any problems. To use these products in hot environments, be careful that they can withstand temperatures ranging from -30 degrees to +90 degrees Celsius.
The important point regarding the operation of this foam in hot environments is that they do not come into direct contact with fire. Also, polyethylene foam is resistant to corrosive substances and dilute acids and will prevent them from penetrating the surfaces. Polyfoam also has a high resistance against insects, so that insects cannot cause holes in it.
One of the other features of polyethylene sheet foam is its sound insulation. In fact, it is considered one of the best sound insulators and can largely prevent the transmission of various sounds and vibrations. Also, it is very easy to install polyfoam in the desired place, and due to its very low weight, its transportation is easy and hassle-free.
Application of polyethylene foam sheet
The unique features of this product have made many different industries prefer to use it. Because these foams are of better quality compared to other existing materials and are considered economical. Polyfoam has wide applications in the following cases:
- Backpack production
- Insulation of electrical appliances
- Insulation of ventilation channels
- Production of sports flooring
- Making different bumpers
- Insulation of water pipes of tanks
- Production of sports and medical mats
- Packaging industry as a shock absorber
- Making a helmet as an inner layer
- Making decorative items and home decoration
- Insulating the floors of houses to prevent the transfer of cold
- Sealing doors and windows of offices and residential buildings
- Automotive industry for inside doors, behind lights, dashboard and car roof
Also, polyfoams are used in amusement parks, heat insulation for refrigerators, parquet substructure, production of wrestling and gymnastics mats.
The price of sheet polyethylene foam and checking its other characteristics
This foam has a very low density so that its weight is equal to 25 kg per cubic meter. It can be produced in different colors such as white, black, green and red. This category of polyfoams are usually produced in sheets with dimensions of 2 meters long and 1 meter wide and different thicknesses (1, 2, 3, 4, 5, 6, 8, 10 to 30 mm) so that users can choose the best according to their needs. They choose the item.
Polyethylene sheets can be easily cut with simple razors if needed. They have a very long shelf life and are completely fiber-free. Therefore, unlike glass wool, they do not produce any fine dust. The price of polyethylene foam sheet depends on various factors.
In what industries is polyethylene foam sheet used?
Polyethylene Foam Sheet is used in many industries and applications. This type of foam is known for its insulating and light properties, resistant to water, impact and heat, ability to absorb pressure, vibration and sound, and high flexibility.
