Flexible LDPE Closed Cell Polyethylene XPE IXPE Foam R Value Heat Insulation PE Foam Sheet Roll

Product Description

IXPE (Electronic Crosslinked polyethylene Foam material)
- Dedicated high density IXPE for wpc/spc flooring -
Product Introduction :
IXPE, also known as electron crosslinked polyethylene foam material, is based on LDPE or modified LDPE resin. Through electron crosslinking processing technology, the high energy electron beam generated by electron accelerator is used to change the molecular structure of LDPE, forming a tight three-dimensional network structure. Finally, the closed cell foam material is made by high temperature foaming to 3-38 times, and the magnification range is large. A wide range of applications.
Product advantage :
IXPE pores are more uniform and fine, the surface is smooth, easy to secondary processing, independent closed-cell structure and the density of polyolefin molecular structure itself, effectively prevent water penetration, with water resistance, water insulation, heat insulation, silent, sound insulation effect, no chemical residue, does not produce harmful gases, is a functional material in line with international environmental standards.
Field of Application :
At present, it is mainly concentrated in the field of WPC and SPC flooring
Product Features:

Application to the floor field related features
Strong pressure resistance	High compressive strength, even if long-term pressure, will not make the floor sag deformation
Heat preservation and insulation	Low thermal conductivity, can block heat or cold air through the ground loss, effectively reduce the use of air conditioning and heating, energy saving
Sound and shock absorption	Sound insulation and noise reduction, enhance the privacy of the house, block the noise up and down the floor or next door, reduce the footsteps of people walking
Water and moisture proof	Antibacterial moisture-proof, isolation of the floor damp gas, prolong the life of the floor
Anti-fungus and mildew	Corrosion-resistant mildew and mothproof, water is not mildew and not rot, not afraid of moth-eaten rats
