What Is XPE Material?

- Sep 19, 2020-

XPE material is chemically cross-linked polyethylene foamed cotton, which is a closed-cell structure, which is the so-called independent foaming, so it has various advantages of independent foaming materials.


XPE is a kind of PE. XPE is a chemical PE foam made from PE raw materials after foaming. XPE foam is a chemically cross-linked polyethylene foam material, which is made of low-density polyethylene resin plus cross-linking agent and foaming agent through high-temperature continuous foaming. It is similar to EPE (physical foamed polyethylene, commonly known as pearl cotton). Compared with, the tensile strength is higher and the cells are finer. XPE is an ideal material for heat preservation of automobiles and air conditioners. It has developed rapidly in the sports and leisure goods market in recent years, such as surfboards, moisture-proof mats, and yoga mats. It also has certain uses in construction, and it has more extensive applications in flame retardant materials. It has been widely used in the automotive and packaging industries recently.


XPE is a non-crosslinked closed cell structure, also known as chemically crosslinked PE, which is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene grease through physical foaming to produce countless independent bubbles. It overcomes the shortcomings of ordinary styrofoam that are fragile, deformed and poor in recovery. It has many advantages such as water-proof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials.


Features of XPE foam:

1. Cushioning property-semi-rigid foam, it will not lose its original performance after strong impact. It is mostly used in precision instruments, semiconductor packaging and other fields. At the same time, it can also be used for sports protective equipment and sports protection products. The production field of leisure products.


2. Formability-strong heat resistance, good ductility, uniform density, can realize deep parts such as vacuum forming and thermoforming, so it can be used for interior parts and shoes such as automobile air-conditioning evaporation cabinet, automobile hot-pressed ceiling, etc. Material aspects.


3. Sound absorption-it has the function of sound absorption and noise reduction, suitable for sound absorption and sound insulation materials in the environment such as airplanes, railway vehicles, automobiles, electric motors and other strong noise equipment.


4. Thermal insulation-its fine independent bubble structure can effectively reduce the energy exchange caused by air convection, and it is suitable for making insulation pipes and insulation boards. It also has anti-condensation properties, making it extremely suitable for heat preservation materials in humid environments such as refrigerators, air conditioners and cold storage.


In addition, XPE also has the properties of non-toxic, odorless, chemical resistance, oil resistance, acid resistance, halogen resistance and other various chemicals, and it is very easy to process, can be cut at will, and fit with a variety of materials, as a new generation High-efficiency, energy-saving and environmentally friendly materials will have broad development prospects.
