PP hollow formwork is made mainly from modified polypropylene, with added toughening, anti-aging, and reinforcing additives. It's produced through an extrusion molding process to create a new type of reusable construction form with a hollow grid inside and solid, smooth surfaces on both sides. This green building material replaces traditional plywood, bamboo plywood, steel forms, and solid PVC forms. The product has very low water absorption, doesn't swell, resists salt and alkali corrosion, and can be used stably in outdoor, basement, and coastal humid conditions. Its smooth surface prevents concrete from sticking, so most constructions don't need a release agent, and after removing the formwork the surface is flat, reducing plaster repairs. The panels are stable in both hot and cold conditions-they don't soften easily in heat or crack in cold-and under standard conditions, they can be reused 60-100 times, far more than bamboo or wood forms. Waste panels and scraps can be 100% crushed and recycled, producing no construction waste and being environmentally friendly. It's widely used in high-rise residential buildings, commercial buildings, factories, civil air defense basements, municipal utility tunnels, bridges, water reservoirs, coastal projects, and precast component factories, making it a mainstream formwork product for standardized, long-term reuse construction projects.

Product Advantage
Higher turnover, lower overall cost
When used properly, PP Hollow Formwork can be reused 60–120 times, far exceeding the lifespan of wooden forms (3–8 times) and bamboo plywood (around 10 times). For long-term projects, it eliminates frequent repurchases. Additionally, PP Hollow Formwork requires no moisture-proof or anti-corrosion maintenance during storage, delivering outstanding long-term cost performance.
Waterproof and corrosion-resistant, suitable for harsh environments
PP Hollow Formwork features ultra-low water absorption, so it will not swell, delaminate, warp or peel when exposed to rain or long-term soaking. It resists cement alkalinity, groundwater and coastal salt spray corrosion. Unlike wooden formwork, PP Hollow Formwork avoids mildew and insect infestation, and unlike steel formwork, it never rusts. It supports uncovered outdoor storage and is highly suitable for basements, water conservancy projects and port engineering.
Concrete shapes well and saves on labor and materials
PP Hollow Formwork adopts double-sided high-gloss dense surface that does not stick to cement, eliminating the need for release agent application during conventional construction. After demolding, walls and beams present a smooth and flat finish with few honeycomb defects, which greatly reduces secondary plastering and repair work, and saves mortar materials and labor costs.
Fully recyclable, eco-friendly and pollution-free
PP Hollow Formwork is free of formaldehyde and other harmful volatile substances, producing no pungent odor during construction. It reduces wood consumption and construction waste, fully complying with green construction and low-carbon building material standards.
Product Application
Application of PP hollow formwork
Residential and commercial buildings
For high-rise, mid-rise residential, resettlement housing, and apartment shear walls, as well as interior and exterior wall formwork.
Municipal Road and Bridge Projects
Underground utility tunnels, box culverts, rain and sewage channels, and slope retaining walls are in long-term contact with mud and alkaline groundwater, so their corrosion resistance stands out.
Water conservation and environmental protection projects
Reservoirs, sewage treatment tanks, river embankment walls, channel linings, aquaculture ponds.
Industrial and coastal special projects
Standard factory buildings, steel structure supporting equipment foundations, floors and ground beams, coastal port areas, buildings in saline-alkali regions.

FAQ
Q1: Are you a manufacturer or trading company?
A1: We are a professional manufacturer specializing in PP hollow formwork. We own a 150,000-square-meter production base with complete independent export qualifications, providing genuine factory direct supply for global clients.
Q2: Which markets do you export your PP hollow formwork to?
A2: Our high-performance PP hollow formwork is widely exported to Southeast Asia, the Middle East, Africa, Europe and America. Up to now, our products have been applied in construction projects across more than 70 countries worldwide.
Q3: What materials are used for your PP hollow formwork, and is it waterproof and corrosion-resistant?
A3: Our PP hollow formwork is made of pure virgin PP material with a scientific hollow structure. It features excellent waterproof, acid and alkali corrosion resistance. It remains stable without deformation even after long-term water immersion, perfectly suitable for coastal buildings, underground projects and water conservancy engineering.
Q4: How many times can PP hollow formwork be reused in construction?
A4: Under standard construction specifications, our PP hollow formwork can be reused 60 to 100 times. Its service life is far superior to traditional wooden and bamboo plywood, greatly reducing construction material replacement costs.
Q5: Can PP hollow formwork withstand extreme high and low temperatures?
A5: Our PP hollow formwork maintains stable structural performance at temperatures ranging from -20℃ to 60℃. It will not soften, warp or deform, adapting to both high-temperature tropical areas and low-temperature cold-region construction scenarios.
Q6: What is the MOQ for bulk orders of PP hollow formwork?
