Reusable Over 50 Times Plastic Construction Formwork Waterproof Fire Retardant
Plastic Formwork Introduction
Made of modified polypropylene, hollow honeycomb PP hollow building formwork comes with internal reinforcing ribs, featuring light weight and cost-effectiveness. It can be reused 50 to 80 times, ranking as the top option for civil construction, wall and floor slab projects with the largest market shipment volume.
PVC building formwork adopts high-density rigid PVC raw material. It boasts high bearing capacity, outstanding compression resistance, superior waterproof and anti-corrosion property as well as stable solid structure free of deformation, specially designed for special-shaped large structures such as culverts, hydraulic projects and sewage tanks.
Plastic Formwork Classification
1. PP Hollow Plastic Formwork
PP Hollow Plastic Formwork Made of modified polypropylene with hollow ribbed honeycomb structure, it is lightweight and cost-effective with the largest market shipment volume. It can be reused 50 to 100 times, serving as the preferred choice for civil construction, wall panels and floor slabs.
2. PVC Plastic Formwork
Manufactured from high-density rigid PVC plastic formwork, this solid formwork resists deformation and heavy loads with outstanding waterproof and anti-corrosion properties. It achieves 50–100 reuse times and is specially applied for culverts, hydraulic projects, sewage tanks and other large irregular structures.
Plastic Formwork Advantages(1-6 )
1. Plastic Formwork High reusability
PP, PVC & ABS plastic formwork can be reused over 50 times vs 3–8 times for wooden plywood, lowering unit construction cost.
2. Plastic Formwork Waterproof & dimensionally stable
No swelling or cracking when wet, available for construction on rainy days.
3. Plastic Formwork Release agent free
Smooth surface produces fair-faced concrete and saves release oil expense.
4. Plastic Formwork Easy installation
Cuttable, drillable and nailable; snap-fit modular type requires no nails to save labor cost.
5. Plastic Formwork Eco & recyclable
Waste formwork is fully recyclable, no construction waste.
6. Plastic Formwork Decay & weather resistant
Anti-termite, anti-mold, anti-aging under harsh hot & humid climates in Southeast Asia and Africa.
