PP Hollow Plastic Board, also called PP hollow sheet or hollow plastic formwork, is a premium engineered polypropylene panel designed for heavy-duty concrete forming, construction, and industrial applications. Combining lightweight convenience, exceptional structural strength, and long-term reusability, it replaces traditional plywood and wood to deliver lower total cost, better sustainability, and smoother construction workflows.
What Is PP Hollow Plastic Board?
Lianggong PP Hollow Plastic Board uses high-performance imported engineering resin as the base material, reinforced with professional additives for toughening, strengthening, waterproofing, anti-aging, and fire-resistant performance. The hollow core structure creates an ideal strength-to-weight ratio for reliable concrete shaping in walls, columns, slabs, and other structural components.
