Advantages of hollow plastic formwork VS assembled plastic formwork

With the continuous development of the construction industry, formwork, as an indispensable tool in concrete pouring, is also constantly being updated. Currently, there are two main types of hollow plastic formwork and assembled plastic formwork on the market. In comparison, hollow plastic formwork has more advantages. This article will conduct a comparative analysis of hollow plastic formwork and assembled plastic formwork, and explain the advantages of hollow plastic formwork.

First of all, hollow plastic formwork is lighter and easier to install and disassemble than assembled plastic formwork. Hollow plastic formwork adopts hollow design and weighs only 15-25kg/square meter, while the weight of assembled plastic formwork is 20-30kg/square meter. Due to its lighter weight, hollow plastic formwork saves more time and effort during transportation, installation and disassembly, effectively improving construction efficiency.

     Secondly, the performance of the hollow plastic formwork is stable and the coefficient of thermal expansion and contraction is small. The hollow plastic formwork is made of high-strength polypropylene resin as raw material, which is extruded at one time under high temperature and high pressure, and has higher compressive strength and impact resistance. Temperature resistance -20-70 degrees, not brittle. After being reinforced with timber, the hollow plastic formwork is not easily deformed, cracked or exploded when pouring concrete, ensuring construction quality.

     Third, the insulation performance of hollow plastic formworks is better. Since the hollow plastic formwork adopts a hollow design, it has good thermal insulation properties, which can effectively reduce the temperature difference between the inside and outside of the concrete and avoid cracks in the concrete due to excessive temperature differences. In contrast, the thermal insulation performance of prefabricated plastic formwork is poor, which can easily cause the temperature difference between the inside and outside of the concrete to be too large, increasing the risk of concrete cracking.

     Fourth, the hollow plastic formwork is anti-corrosive and waterproof, and the manufacturer can customize the size. The hollow plastic formwork is anti-corrosion, acid and alkali resistant, and will not delaminate when soaked in water. The manufacturer can customize the size, color, thickness, strength, etc. Save costs and improve construction efficiency.

Fifth, the environmental performance of hollow plastic formwork is better. The hollow plastic formwork can be recycled and reused, which is in line with the concept of green environmental protection. At the same time, the use of environmentally friendly materials and processes in the production process can effectively reduce environmental pollution. In contrast, prefabricated plastic formwork generally cannot be recycled and reused, and some environmental pollution may occur during the production process.

To sum up, compared with assembled plastic formwork, hollow plastic formwork has the advantages of being lightweight and easy to install, high load-bearing capacity, excellent thermal insulation performance, ultra-long service life and better environmental performance. In actual applications, the appropriate formwork type can be selected according to specific needs.
