Foam is a kind of plastic foaming material, and its material composition is polyurethane. Foam has the advantages of good water absorption, impact resistance, corrosion resistance, insulation and processability, and is widely used in packaging, earthquake prevention, sound insulation, filtration and other fields.

PE foam is a special kind of foam material, and its main component is polyethylene. PE foam has high temperature resistance, flexibility, toughness and resilience, and has good sound insulation, shock absorption, moisture resistance, waterproof and other characteristics, and is widely used in electronics, electrical appliances, automobiles, buildings and other fields.

Compared with ordinary foam, PE foam has higher flexibility and resilience, and can better absorb impact energy, so it has better protective performance in practical application. In addition, PE foam has better water resistance and temperature resistance, and can be used in worse environment.
