PP Hollow Plastic Formwork Board - 15mm, 18mm, 20mm Supplier

PP Hollow Plastic Formwork

PP Hollow Plastic Formwork provides an energy-saving, environmentally protective alternative to traditional wood, steel, and bamboo formwork systems. Manufactured from polypropylene (PP), the thermoplastic polymer features a hollow core structure that reduces weight while maintaining structural performance. Enhanced variants incorporate continuous fiberglass-reinforced material for increased strength and durability.

The formwork delivers exceptional reusability with over 50 cycles possible, along with resistance to moisture, corrosion, and chemicals. The non-hygroscopic material maintains dimensional stability from -20°C to +60°C and weighs approximately 29kg for a 1220x2440mm panel at 18mm thickness. Performance specifications include bending strength exceeding 25MPa and modulus reaching over 1800MPa.

Standard panel sizes of 1220x2440mm and 915x1830mm accommodate walls, columns, slabs, beams, tunnels, bridges, and culverts. Installation mirrors wooden formwork methods with panels positioned perpendicular to supports and joints sealed with tape. No release agent is required due to the non-stick surface, and fastening uses 30-35mm nails.

Quality assurance includes flexibility, impact strength, and thermal shrinkage testing. Customization options cover dimensions, color, and surface texture, with modifications possible using standard woodworking tools. The lightweight design reduces labor requirements while maintaining compatibility with other formwork materials.
