The polyethylene Foam is made up of millions of very tiny bubbles. These bubbles could not interact with each other, they are sealed off. This feature of the polyethylene which is closed-cell makes it water resistant. It is strong and rigid unlike open-cell type of foams. This also resists liquid and petroleum products at the same time it is antimicrobial prohibiting mold and bacteria to grow on its surface. The polyethylene is a resilient material in that it returns to its form right after undergoing the pressure of compression. This characteristic of the polyethylene makes it very useful in different levels of application.
Polyethylene foam is formed after heating polymer compounds. The foam receives additional ingredient to its formula in order to change some of its properties before heating it thereby taking up its solid form. Aside from having the characteristics of the polyethylene sheet, it also becomes not readily susceptible to fire. This type of foam is also made available in different densities depending upon its use. The cell walls in foams that have higher density are much thicker and the material created is much stronger.
The polyethylene foam has an anti-static property which makes it a good choice for packaging and in transporting of electronic products. The foam will dissipate charges from the device that might destroy the components of the product. The foam also is fire retardant in that it resists flames up to a certain point. Once it is ignited, it can also extinguish the flames. The product is good as an insulator and also is commonly used in construction.
Aside from its characteristics that make it very useful whether in packaging or transporting, the foam can also be readily available in different sizes and shapes. The polyethylene is also rigid thus maintaining its shape when it is being sliced into thicker sections. These foams are commonly used as packaging materials and as insulating materials because it is very strong and absorbs shock at the same time it can be readily cut into packets in order to securely move delicate objects and devices. The closed-cell foam is highly recommended if you want to resist moisture on your equipment or device and the polyethylene serves as thermal insulation for your devices.
Polyethylene is also handy in that it can be easily laminated in order to create much thicker potions. You may use this for furniture insert purposes, flotation device inserts and other specialized packaging. You may also add dyes so your foam will be visually appealing. The foams are often seen in the shade of black, blue, white, pink and gray.
