Water-proof Paperbacked Plasterboard Waterproof Paperbacked Plasterboards are high-quality paperbacked plasterboard made of high purity gypsum cores, high-quality, high-strength environment-friendly lining paper and organic silicon additives. The adopted green surface paper undergoing special treatment with organic waterproof material dramatically improves the waterproof property of plasterboards, so it is applicable to indoor places with high moisture content or temporary outdoor places. Waterproof Paperbacked Plasterboards, with a water absorption rate of less than 10 percent, are in strict compliance with ASTMC1396 and GB/T9775.

Raw materials include plaster of Paris, surface paperboards, caking agents, accelerating agents, additives, etc. Natural gypsum ores are the main raw material of paperbacked plasterboards. we adopts high purity environmental FGD gypsum.Advantages of Plasterboard 1. High-purity gypsum cores, high-quality and high-strength surface paper, imported equipment and internationally advanced production techniques. 2. High strength, small weight, high nail-holding ability, smoothness, a low water ratio, etc. 3. A variety of types of high-performance paperbacked plasterboards such as standard plasterboards, water-proof plasterboards, fire-proof plasterboards, etc. 4. Production in strict compliance with ASTMC1396 (USA standard) and GB/T9775 (Chinese standard). 5. A perfect plasterboard system achieved through the cooperation with Light Steel Keels.
