XLPE, XPE Foam Sheet
Features
XLPE is chemically crosslinked PE foam. It is produced in continuous rolls resulting in a foam product with uniform, closed cells and smooth skins on both sides. It is light weight, flexible and soft to touch, yet strong, tough, resilient and resistant to moisture, many chemicals and temperature extremes.
Compared with non-crosslinked polyethylene foam, it typically offers superior thermal stability and insulating properties plus improved dimensional consistency and stability over a wide range of fabrication methods and end-user’s conditions.
XLPE foams are used as insulation and sound absorbing materials in a host of container’s designs.
It is easy to work in fabricating and thermoforming. XLPE foams are right at home in the building and construction industry where thermal insulation, moisture resistance, sound and vibration are critical. Indoor or outdoor XLPE foams build success.
XLPE foams also used in backpack padding, luggage and similar application are benefiting from a wide array of beautiful colors and variable densities.
