Hollow Plastic Formwork Panel Exporters & Service

Polypropylene (PP) hollow formwork features an engineered internal cellular rib matrix that delivers a high strength-to-weight ratio. PP is significantly more tough, flexible, and impact-resistant than PVC (Polyvinyl Chloride). Generic solid PVC boards are heavy, prone to brittle edge cracking when dropped, and become soft under direct sunlight. PP hollow panels weigh 40% less, making them easy to handle while offering superior thermal stability (-20°C to +85°C) and higher fatigue resistance over 60+ pour cycles.

No release agent is required! Polypropylene is a non-polar polymer with an ultra-low surface energy that naturally repels wet concrete slurry. After concrete curing, the shuttering boards detach effortlessly from the concrete wall or slab face without sticking. Eliminating release agents saves chemical purchasing costs, eliminates oil staining on the concrete surface, and speeds up site cleanup.

Greenstar PP hollow plastic formwork can be cut, drilled, nailed, and sawed using standard carpentry tools identically to wooden plywood. You can use standard handheld circular saws, handheld hand saws, or CNC routers. The nail-holding power of our reinforced polymer formulation is exceptional (holding strength > 8,500 N), meaning nails driven into the hollow panel remain secure during high-amplitude concrete vibration.

To evaluate panel quality on-site: 1) Check Weight per Sheet: Standard 18mm PP panels should weigh approximately 13.5 kg to 14.5 kg per sheet (1220x2440mm). Low-weight panels lack internal rib wall thickness. 2) Check Surface Flatness: Premium virgin PP boards show a uniform color without wave-like distortion. 3) Impact Test: Strike the corner of the panel with a 5kg hammer—low-grade brittle boards will fracture, whereas high-grade modified PP will absorb the impact without cracking.

With 8 automated extrusion lines operating continuously near major shipping hubs (Lianyungang, Qingdao, and Shanghai ports), our standard factory lead time is 7 to 15 days upon receiving the deposit. Emergency project orders can be expedited through dedicated line scheduling.

Yes! Polypropylene is 100% recyclable. After completing 60 to 100 pours, damaged or worn-out boards can be crushed, re-pelletized, and processed back into industrial plastic products. We assist global clients with circular economic recycling schemes to meet corporate sustainability goals.
