Polyethylene (PE)

16.06.2021

Its chemical formula is (C2H4)n, i.e. this is a carbon- and hydrogen-based material. Polyethylene foam is a closed cell solid material and is foamed with gas. Each gas phase is separated by a layer, which yield the cells. Closed cell cross-linked polyethylene foam is the sum of these cells.

Cross-linked PE foam is flexible and absorbs vibrations thanks to the structure of the foaming material. Its thickness (4-500 mm) and density (approx. 0.03 – 0.2 g/cm3) are variable, and it is a lightweight material (up to 30 times lighter than water).

Polyethylene foam is environmentally and skin-friendly, and harmless to the human body.

Polyethylene belongs to the family of polyolefins in addition to polypropylene.
