PP formwork is a new type of construction formwork made primarily of polypropylene (PP) resin through high-temperature extrusion and molding processes. Compared to traditional wooden formwork, PP formwork is waterproof, moisture-proof, corrosion-resistant, and lightweight, making it increasingly widely used in concrete pouring projects.
Because PP material itself does not absorb water, the formwork will not swell, deform, or rot even after prolonged contact with cement slurry and rainwater. Furthermore, the smooth surface of PP formwork ensures good demolding, reducing the need for concrete surface repairs and improving construction efficiency.
PP formwork can be reused dozens or even hundreds of times, effectively reducing the overall cost of construction projects and minimizing timber consumption, aligning with the trend of green building. As the construction industry's requirements for environmental protection and construction efficiency continue to increase, PP formwork is gradually becoming one of the important formwork materials in modern construction projects.
