PE foam (polyethylene foam), that is, polyethylene foam, is a foam product made from PE raw materials through foaming. PE foam has good thermal insulation properties. In addition, PE foam has good cushioning and shock absorption performance, good weather resistance, and good aging resistance. It has been widely used in various aspects such as agricultural industry, automotive electronics and civilian use. According to the different foam molding process, PE foam is divided into EPE, XPE, IXPE, etc., each of which has its own characteristics.
Common types of PE foam: XPE (chemical crosslinked) IXPE (irradiated crosslinked)
The use of PE foam
PE foam, the production base materials are all non-toxic high molecular polymers, using foaming agent or ion irradiation to act on the raw materials, so that PE (polyethylene) will be cross-linked to change the original structure of the base material, thus forming The net-shaped independent closed-cell cell structure makes the product surface smooth, excellent in resilience, and high in mechanical strength; it has excellent heat insulation, waterproof and moisture resistance; improved aging resistance and chemical corrosion resistance; stable volume and high sound insulation performance. PE foam can be subjected to secondary molding processes such as compounding, bonding, and cutting.
Suitable for PE foam processing technology
Heat the mold, then put the sheet or coil material into the mold, evacuate the air, and cool the shape.
Using hydraulic punching machine, CNC engraving machine, etc., the material is punched into the shape required by the customer.
Use PE (polyethylene) as the medium to compound different materials with PE foam
