PP Hollow Plastic Formwork Lightweight Reusable Water Resistant
PP Formwork Introduction
Our PP hollow plastic formwork is manufactured with high-modified polypropylene material, serving as an ideal substitute for wooden and steel formwork in modern construction. Thanks to the hollow structure, the panel is lightweight for easy carrying and fast splicing, helping clients save transportation and installation expenses. Excellent waterproof performance avoids water soaking, swelling and mold damage under wet construction conditions.
The product realizes over 100 times of cyclic reuse and recyclable processing after scrapping. Its smooth surface removes the need for release agent and delivers flawless concrete surface after stripping. Suitable for wall, column, beam and foundation casting, it is an economical and eco-friendly building accessory worldwide.

PP Formwork Advantages
1. Lightweight High Strength, Fast Installation
- About 1/7 the weight of steel formwork, easy manual handling. Cuttable, nailable, drillable. Saves 30%+ labor time.
2. Waterproof & Corrosion Resistant
- Zero water absorption, no rot, no rust. Stable in humid, coastal or rainy conditions. Resists acids & alkalis for long service life.
3. High Reuse, Lower Total Cost
- 50–100 reuses vs. 3–8 for wood. Less frequent replacement. Cost per use ~50% lower than plywood.
4. Smooth Fair‑Faced Finish
- Concrete surface smooth & flat after stripping. No plastering needed, saves materials & time.
5. Fire Retardant & Dimensional Stability
- Flame‑retardant grade meets safety standards. Low thermal expansion, stable dimensions in extreme temperatures.
6. Fully Recyclable, Eco‑Friendly
- Waste panels can be recycled & reprocessed. No construction waste. Replaces wood, protects forests.
