Carpet and rug PU backing

Modern carpets and rugs use PU coatings or foam backings on the bottom face to stabilize fibers, prevent piece movement, provide cushioning and, in residential/commercial carpets, confer properties such as acoustic insulation and water resistance. Traditionally dominated by SBR (styrene-butadiene rubber) in volume applications, PU backing grows in premium segments: automotive carpets (PU backing is standard in premium vehicles due to better acoustic and dimensional performance), high-traffic commercial carpets (offices, hotels, airports — PU backing has superior durability), premium residential rugs. Waterborne PU systems are replacing solvent-based globally due to environmental pressure. PU foam backing is a specific application where a thin layer of PU foam (3-5 mm) applied by spray or molded integrated provides significant cushioning and acoustic insulation — particularly used in automotive carpets.
