XPE is chemical cross-linked polyethylene foaming material, is made of low-density polyethylene resin crosslinking agent and foaming agent after high temperature continuous foaming, compared with EPE (physical foam polyethylene, commonly known as pearl cotton), the pull strength is higher, bubble holes are thinner.
Characteristics: XPE is a non-cross-linked closed-hole structure, also known as chemical cross-link PE, is a new type of environmentally friendly packaging materials. It consists of numerous independent bubbles produced by low density polyethylene fat through physical foaming. Overcome the shortcomings of ordinary stylus fragile, deformation and poor reply. It has many advantages, such as moisture protection, shockproof, soundproofing, insulation, good plastic performance, strong toughness, regeneration, environmental protection, strong impact resistance, etc., and also has good chemical resistance. Ideal alternative to traditional packaging materials.
XPE chemical foam characteristics:
1. Buffering - for semi-hard foaming body, after strong impact also lost the original performance, more used in precision instruments, semiconductor packaging and other fields, but also can use its easy molding, but for sports protective and leisure supplies production field.
2. Formability - strong heat resistance, good extension performance, uniform density, can achieve vacuum molding and thermotypeing and other deep parts of the molding, and thus can be used in automotive air conditioning evaporation cabinets, automotive hot-press roof and other interior parts and shoe materials.
3. Sound absorption - with sound-absorbing noise reduction function, suitable for aircraft, railway vehicles, automobiles, electric motors and other strong noise equipment and environment sound-absorbing soundproofing materials.
4. Insulation - its fine independent bubble structure, can effectively reduce the air flow caused by the exchange, suitable for the production of insulation tube, insulation plate. And both anti-dew, making it suitable for refrigerators, air conditioners and cold storage and other humid environment of insulation materials. In addition, XPE also has, tasteless, drug resistance, oil resistance, acid resistance, halogen resistance and other types of chemical properties, and very easy to process, can be cut at will, with a variety of materials, as a new generation of energy-saving, environmentally friendly materials will have broad prospects for development.
