Flooring Underlayment foam
Top layer---Concrete floors
Second layer--- 2nd Storey floors
Middle layer----Wooden floors
Bottom layer----Where a sound-deadening barrier is required. ( FOAM underlayment)
Huzhou CYG Tefa's flooring Underlayment foam t is a basic underlayment manufactured by using a closed-cell polyethylene microcellular foam.
There are two kinds of foam is able to apply in flooring underlayment.
● XPE FOAM underlayment
The XPE (Chemically Cross-linked Polyethylene) foam is polymer material with great thermal insulation, sound absorption, and vapor resistance properties.
The structure of this flooring underlay XPE：
XPE foam laminated with aluminum foil in the single side or both sides.
The aluminum foil plays the role of reflecting radiation heat from sunshine with reflectivity of 96-97%. And the foam has the function of trapping air so as to stop convection heat. Most importantly, in response to customer's flame retardant requirement, our XPE foam can be made fireproof so that this product will not easily catch fire and will not encourage fire when fire hazard happens.
● IXPE foam underlayment
The IXPE (Irradiated Cross-linked Polyethylene) foam is a polymer material has good properties of thermal insulation, sound absorption, vapor resistance, etc.
Compared with XPE foam, IXPE foam has a more delicate cellular, more smooth and flat surface, more excellent mechanical performance.

• CYG can customize length and width as request.
• CYG Floor underlay is normally laminated on the floor to make installation faster, so we provide large rolls (max 500 m/roll) for customers’ production directly.
• Normal package: pe bag in a roll with a 3-inch inner paper coil.
Suitable for wood and cement subfloors and all other floating floors
HUZHOU CYG has passed the IATF16949, ISO9001.
