Hollow plastic building formwork is a kind of environmentally friendly and energy-saving product. It is high-performance, functional and specialized, and is widely used in the construction field to help build industrial modular frame systems.
TOPOLO innovatively combines a layer of CFRT sheet on the surface of PP hollow plastic building formwork. In this way , the building formwork does not require release agent when used, and can be recycled more than a hundred times.
Panel Structure
Surface Layer Continuous fiberglass reinforced thermoplastic (CFRT) sheet is thermally laminated by two or more layers of thermoplastic UD tapes and has high strength and toughness.
Core Layer It is made of polypropylene (PP) resin using an extrusion process, and has a regular structure to ensure uniform stress.

Advantages of PP Hollow Plastic Building Formwork
·Strong impact-resistant PP hollow plastic building formwork has extremely excellent mechanical strength and impact resistance. At the same time, its own weight is only half of ordinary plastic formwork, making it a model of new lightweight panels.
·Good stability Whether the temperature is too high or too low, or the environment is too humid, it can maintain a stable structure and is not prone to expansion and deformation. This is very beneficial for building construction.
·Waterproof and corrosion-resistant CFRT layer on the surface plays a waterproof role in the entire panel. The CFRT skin and PP core are both corrosion-resistant matrices, which can better touch with building materials.
·Reusable Hollow plastic building formworks are 100% recyclable and can be reused more than 100 times.
·Easy to process and install The addition of CFRT sheet, makes the building formwork smoother. There is no need to use release agent anymore, making it easier for workers to disassemble and assemble, greatly reducing the difficulty of construction.
