As an experienced gypsum board supplier and moisture resistant gypsum board wholesaler, we manufacture 9.5mm water resistant plasterboard specifically engineered for interior applications where moderate humidity resistance is required. This lightweight panel, sized 1220×2440mm (4×8 ft), features a specially modified gypsum core with water-repellent additives and treated facing paper, offering a practical solution that balances reduced weight with enhanced moisture performance.
The moisture resistance of this gypsum board is achieved through advanced core modification. Siloxane-based water-repellent agents are incorporated into the gypsum slurry during production, forming a hydrophobic layer on the gypsum crystals that effectively blocks capillary water absorption. Combined with moisture-resistant facing and backing paper, the board achieves a water absorption rate of only 6.8% — significantly lower than standard gypsum board (often above 20%). This technology maintains dimensional stability and mechanical strength even in environments with relative humidity up to 90%.
