PP Building Hollow Plastic Formwork manufacturer in China

The hollow plastic panel is an environmentally friendly building panel that is blow-molded after being modified and heated by PP (polypropylene), a derivative of petroleum. The hollow plastic formwork does not absorb water, does not deform, and is incompatible with cement, so it does not need to be brushed with a release agent and can be reused more than 100 times, several times that of high-quality wood formwork.

Hollow plastic formwork is rich in types, and its shape and size can be customized according to the requirements of construction projects.

  • It can be reused and lasts a long time

Hollow plastic formwork can be recycled and reused to reduce production costs. Compared with other templates, it makes full use of waste raw materials. Due to its light structure, it is widely applicable to various buildings and bridge structures. It has the advantages of high strength, good impact resistance and good wear resistance, so the service life can be extended.

  • Good toughness, water resistance and corrosion resistance
  1. The hollow plastic formwork has sufficient toughness and tension, and is not easy to warp and break.
  2. Due to the characteristics of plastic, even if the plastic formwork is soaked in water for a long time, it will not delaminate or bubble.
  3. It has good anti-corrosion properties. It can be used in special projects such as coastal areas, river dams, mines, etc., and does not require any anti-corrosion treatment, and will not pollute the concrete surface.
  • Easy construction

Due to the lightness of plastic building formwork, it can be operated conveniently, quickly and safely, which is conducive to organizing construction and improving construction efficiency.

PP vs Wood vs Bamboo vs Steel Formwork

ProductReuse timesFeature
PP FormworkMore than 50 timesHigh hardness and strength, fire resistance, waterproof, light weight, convenient transportation, many times of turnover, low cost, easy to disassemble
Wood Plywood Formwork1-20 timesEasy to absorb water and expand, reused times is less, waste forest resources
Bamboo Plywood Formwork5-20 timesEasy to absorb water and expand, reused times is less, waste forest resources
Steel Frame FormworkMore than 20 timesHigh cost, inconvenient disassembly, consume labor power and the weight is heaviest

Advantages of TOPOLO Hollow Plastic Formwork

The surface of TOPOLO hollow plastic building formwork is made of CFRT (continuous glass fiber reinforced material), which greatly enhances the strength and toughness of the formwork. Its surface is smooth and smooth, and the splicing between the formworks is tight and smooth. After demoulding, the surface finish of the concrete structure exceeds that of concrete using wooden formwork, and no repairs are required; and the demoulding is easy, no release agent is required; it is stable and weather-resistant, and the mechanical height is strong. Under the temperature condition of -20°C to +60°C, it does not shrink, swell, crack, deform, and has stable dimensions.

Hollow Plastic Formwork Factory

Basic Installation Requirements

  • The joints of the formwork should be tight and flat without misalignment.
  • The joints of the formwork should be on the wood/steel frame. If there are gaps, tape should be used to seal them.
  • The hole direction of the hollow plastic formwork should be perpendicular to the horizontal plane, and the hole should be sealed with adhesive tape to prevent the cement slurry from seeping into the hole.
  • The connection between the hollow plastic formwork and the wood/steel frame should be firm, and no relative displacement should occur during construction.
