For flooring factories, distributors and project contractors, Romeroca supplies underlayment rolls with different thicknesses, densities, films and packaging options for wholesale and OEM flooring projects.
Available options include EVA foam underlayment, IXPE cross-linked polyethylene underlayment, PE film laminated underlay, golden film underlay and aluminum film underlay. The products can be used as loose flooring underlay or as backing material for SPC, LVT and other resilient flooring products.
What Is IXPE/EVA Flooring Underlayment?
IXPE underlayment is an irradiated cross-linked polyethylene foam with a fine closed-cell structure. It is commonly used under SPC, LVT, vinyl plank and laminate flooring where moisture resistance, dimensional support and acoustic comfort are required. EVA underlayment is an ethylene vinyl acetate foam underlay that provides cushioning, sound reduction and cost-effective flooring protection for residential and commercial projects.
For high-end flooring projects, IXPE is often selected for stronger recovery, better dimensional stability and premium acoustic performance. For large-scale budget-sensitive projects, EVA is widely used because it provides good cushioning, moisture resistance and competitive cost performance.
