PP Hollow Plastic Formwork

PP hollow plastic formwork refers to a type of formwork used in construction for creating concrete structures such as walls, columns, and slabs. It can replace wooden or  plywood formwork well because we can use PP hollow plastic formwork more times than wooden formwork. Our product is more durable because it is waterproof, strong strength, good toughness and wear-resistant. What’s more, shaped concrete structure is better than that use wooden formwork as a clean and smooth surface and it doesn’t stick to the cement.

Our formworks are typically sheets that can be assembled to form the desired shape and size of the concrete structure. They are designed to withstand the pressure exerted by wet concrete while providing a smooth finish to the concrete surface.

Comparison between PP hollow plastic formwork with wooden formwork.

Product Reuse Times Features
PP hollow plastic formwork At least 50 times 1. wear-resistant, waterproof, no deformation, no delamination.
2.No brushing oil procedure.
3. It is suitable for curved-surface concrete construction.
wood plywood formwork 1-20 times 1. easy to deform and delamination after absorbing water
2. Brushing oil is necessary.

The advantages of PP hollow plastic formwork.

Lightweight: Polypropylene is a lightweight thermoplastic resin, designed with a scientific hollow structure to make our PP hollow formwork lightweight. It is convenient for workers in the construction sites to handle and transport to improve efficiency.

Durable: Good mechanical properties, good heat resistance, good chemical stability, acid, alkali, and organic solvent resistance. It does not shrink, does not swell when wet, does not crack, does not deform, and is dimensionally stable -10℃ to 75℃ temperature. It is very suitable for applications in coastal areas, mines, sea dams, and other projects. It does not require any anti-corrosion treatment during use and storage and will not pollute the concrete.

Easy to assemble and dismantle: It allows for quick and easy assembly and disassembly, increasing efficiency on the construction site.

Smooth finish: The smooth surface of the plastic formwork produces a high-quality finish on the concrete, eliminating the need for additional finishing work.

Eco-friendly: Use eco-friendly material to produce, no pollution, and there is no waste about forest resources.

Reusable: It is durable and reusable at least 50 times to save the cost of the projects.

Overall, PP hollow plastic formwork offers a cost-effective, efficient, and sustainable solution for concrete construction projects.
