What is polyethylene foam?

Polyethylene is a thermoplastic class of virtually ubiquitous in consumer products. In its foam form, polyethylene is used in packaging, vibration and insulation as a barrier or buoyancy or as a material for suspension. It is most commonly considered to be wrapping material.

Sixty million tonnes of polyethylene is produced every year around the world, which is even more than it sounds like when you are considering its low density. In the UK, polyethylene is known as Polythene. Worldwide, the material is sometimes shortened as PE .

polyethylene is produced by ethylene polymerization. Like other polymers, polyethylene is made up of huge ethylene chains and has a molecular weight in millions. These chains stick together through the weak forces of van der waals, which means that the material can be torn with human hands. Polyethylene with different densities or material properties is created using different catalysts during the polymerization process. For example, HDPE(high density polyethylene) is produced with a catalyst chrome that causes molecular chains to change less and therefore have a higher density.

Polyethylene is hovering, so it is popular for naval use. Most types of polyethylene are non -permission; serves as a thermal insulator; are inert for water, grease and solvents at typical temperatures; They are CFC without CFC and ozone friendly, recyclable, odorless and very light. Many types of polyethylene are approved for use in the food industry.

It is found in all types of packages, polyethylene is used to pack furniture, computer components, electronics, sports goods, plants, frozen food, clothing, bowling balls, brands, metal products and more. It comes in forms designed to minimize static or maximize thermal insulation, among dozens of other variants. MaterialL is for bacteria and MO non -permeable and is resistant to tears. Polyethylene is one of the cheapest of artificially made materials, but not as cheap as most raw materials, because the polymerization process consumes energy. In addition, distribution costs are normal because polyethylene cannot be compressed for transport.
