Polymer Quartz Board

Polymer Quartz Board is a new‑generation composite building substrate, specially developed for humid‑condition areas, tile bedding systems and prefabricated renovation projects. It adopts an integrated multi‑layer laminated composite structure. From base to surface, the layers are base levelling layer, high‑density XPS thermal insulation core, modified polymer‑quartz reinforced layer and wear‑resistant top layer. All functional layers are bonded under high temperature and high pressure without hollow gaps or delamination. Each layer performs its dedicated function to combine thermal insulation, waterproofing, crack‑resistance and high adhesive performance, which makes it different from conventional single‑material cement board or gypsum backer boards

For material and specifications, the core is made of closed‑cell high‑density XPS extruded polystyrene with extremely low water absorption. The upper and lower reinforced layers are polymerized by quartz sand and modified polymer without asbestos or formaldehyde, qualifying it as eco‑friendly building material. Multiple overall thickness options are available: 6mm,10mm,12mm,20mm and custom‑made core thickness. Standard dimension is 1220×2440 mm, non‑standard cutting is acceptable for both on‑site dry construction and off‑site prefabrication. Its light weight enables easy manual handling without heavy lifting machinery, greatly shortening construction schedules

Major strengths lie in wet‑zone compatibility and structural stability. Closed‑cell XPS core blocks moisture penetration. The board will not swell, mildew or decay under persistent high‑humidity conditions. The polymer‑quartz surface features optimized micro‑pore texture to create strong mechanical interlock with tile adhesive, lowering hollowing and tile‑fall‑off risks in thin‑bed tiling. It delivers decoupling performance to absorb substrate deformation stress, preventing cracks transferring from wall base to tile finishes. Class‑A fire‑resistance and high impact resistance ensure no easy fragmentation under physical impact

It fits various interior and exterior working conditions. For bathroom shower enclosures, it serves as direct tile substrate, removing extra waterproof plaster layers thanks to its built‑in waterproof capacity. In damp basements, it acts as moisture barrier for walls and floors to block ground moisture migration. It works as levelling panel for rough bare walls for whole‑house dry fitting. It can also be used as exterior wall integrated insulation‑waterproof substrate, partition wall and ceiling panel for steel‑frame buildings, permanent concrete formwork, ventilation duct liner and acoustic wrapping board for pipes. For instance, during overseas apartment bathroom retrofits, 10 mm polymer quartz board replaces cement and membrane systems. Thin‑set tiling is implemented directly on panels, cutting wet‑site work and solving tile cracking caused by old building settlement deformation

Its outstanding advantage lies in all‑in‑one performance that streamlines construction workflows. Conventional wet‑zone building needs sequential levelling, plastering, waterproof mortar and membrane installation, relying heavily on craft skills and long working cycles. Polymer Quartz Board integrates levelling, waterproofing and anti‑crack substrate functions. Once substrate is prepared, panels can be fixed directly followed by thin‑bed tile installation, drastically reducing wet mortar work on‑site. Decoupling capacity absorbs minor wall shrinkage and settlement stress to stop crack propagation toward tile finishes and lower hollowing and tile‑break risks. Mildew‑proof and Class‑A fire‑rated properties satisfy residential and commercial fire‑safety requirements

It applies to residential renovation, commercial fit‑out and prefabricated construction. Inside dwellings, shower enclosures and vanity back‑walls are typical spots. For bathroom retrofits, panels can be mounted without stripping old wall substrates for fast renovation. It works as moisture barrier for basement walls and floors, and dry‑levelling alternative to thick plaster on bare rough walls. For commercial projects such as hotel bathrooms and apartment mass fit‑outs, it is widely adopted. It also serves as interior partition and ceiling panel for steel‑structure buildings, ventilation duct liner, permanent concrete formwork and acoustic protection board for piping systems. As a real‑world reference: in mass‑fit‑out Southeast‑Asia apartments with tight schedules, polymer quartz boards replaced plaster and waterproof membranes in all bathroom zones. Dry‑fit installation cut per‑unit bathroom construction time by nearly 40 % and effectively reduced after‑sales tile‑cracking complaints
