technical field

The utility model relates to the technical field of pearl cotton, in particular to an EPE plate.

Background technique

EPE (Expandable Polyethylene), also known as pearl cotton, is a non-crosslinked closed-cell structure, which is composed of low-density polyethylene fat through physical foaming to produce countless independent cells. EPE overcomes the shortcomings of ordinary styrofoam such as fragility, deformation, and poor recovery, and has the advantages of waterproof, moisture-proof, recyclable, strong plasticity, and strong toughness. EPE sheets are often used in the field of packaging, but when using EPE sheets, the effects of shock absorption and sound insulation are limited. Therefore, there is an urgent need for an EPE sheet that can solve the existing problems.
