قوالب بلاستيكية مجوفة PP

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.

Standard panel thicknesses range from 10mm up to 150mm. Standard widths include 1000mm, 1220mm, and 1500mm, with maximum single-sheet lengths up to 5800mm (5.8m) to fit ocean freight container shipping dimensions.

2. What are the primary engineering benefits of using PP Hollow Plastic Formworks?

PP Hollow Plastic Formworks deliver an exceptional stiffness-to-weight ratio, rot-proof moisture resistance, reliable thermal insulation, and dynamic fatigue endurance for high-stress applications.

3. How do these composite panels perform under high humidity and outdoor weathering?

The closed-cell core prevents water logging and condensation absorption, while pre-painted skins provide a 20+ year weatherability barrier against UV degradation.

4. What fire safety ratings and quality certifications do these composite panels meet?

Flame-retardant formulations meet EN 13501-1 Class B-s1,d0 and GB8624 Class B1 fire performance standards. Manufacturing quality is governed under ISO9001 management systems, with raw material performance verified under SGS and CE testing.

6. Can these composite panels be CNC grooved, bent, or edge-sealed on-site?

Yes. Pre-painted skins can be V-grooved at 90° or 135° on the reverse side using standard CNC routers or hand tools, allowing manual edge folding into architectural cassettes without surface paint cracking.

7. كيف تُغلَّف شحنات الألواح الكبيرة لمنع تلف الشحن أثناء النقل البحري؟

Panels are packed with protective PE film on both skins, separated by inter-sheet foam layers, and secured on heavy-duty export wooden pallets or CKD steel crates to prevent shipping damage during 20ft and 40ft container freight.
