1. Light weight, high strength, high hardness, impact resistance, wear resistance.

2. Surface is smooth, bright and clean; Concreting and forming effect is good for pp hollow sheet making machine.

3. No absorption of moisture, no deformation, no mildew; Long-term immersion stratification in the water, no bubbles, sheet size stability, especially suitable for underground and damp environment.

4. Good toughness. pp hollow sheet making machine could be used as cambered special-shaped formwork.

5. Acid and alkali resistance, corrosion resistance; pp hollow sheet making machine is very suitable for the engineeringapplication in coastal areas, mine, as well as seawall. pp hollow sheet making machine needs not do any preservative treatment both in using and storing the formwork, which do notpollute the concrete surface.

6. The reusable time for pp hollow sheet making machine can reach more than 60 times, long service life.

7. Waste products can be recycled and reprocessed, making full use of waste materials. This property can greatly reduce the project cost compared with wooden formwork and bamboo formwork.
