Meishuo floor foam underlayment is a basic underlayment manufactured by using a closed-cell polyethylene microcellular foam. The IXPE（Irradiated Cross-linked polyethylene） foam is a polymer material with great thermal insulation, sound absorption, and vapor resistance properties.

Irradiated crosslinking underlay for vinyl flooring as properly as for use under wooden flooring and floor panels to provide the house better sound insulation and less shock noise from neighbors when they walk in high heels. Modern IXPE foam underlay is can directly lay under the flooring when installation in small roll, another type, the manufacturer also pre-laminated the IXPE foam beneath the flooring panel to increase anti-slip layer protecting refined fasteners of vinyl panels towards damage. Meishuo foam supplies both types.
