XLPE
Insulation

Airmaster Thermal Insulation – CROSS LINKED POLYOLEFIN FOAM

Fire resistance & low toxic smoke emission

Environment friendly

Excellent thermal efficiency

Cost saving

Zero water vapor permeability and low water absorption rate

Cross Linked Polyolefin Foam

XLPE is chemically crosslinked Polyolefin foam is extremely fine closed cells foam and smooth skins on both sides. It is light in weight, flexible, soft in touch, strong and tough in physical properties, resilient and resistant to moisture, chemicals and extreme temperature. It typically offers superior thermal stability and insulating properties improved dimensional consistency and stability over a wide range of fabrication methods and end-user’s conditions. It is easy to work in fabricating and thermoforming. XLPE foams work well in the building and construction industry where thermal insulation, sound and vibration are critical, due to its low moisture permeability and high buoyancy.

XLPE Properties:

  • Resilient
  • Excellent buoyancy
  • Good thermal insulator
  • Excellent strength and shock absorption
  • Low water absorption
  • Impervious to mildew, mold, rot, and bacteria
  • Excellent chemical resistance
  • Nontoxic and contains no CFCs, HCFCs, or hydrocarbon blowing agents
