What are the advantages Comparison of Hollow Plastic Formwork and solid PVC foamed construction plastic formwork?
PRODUCT | New hollow plastic building formwork | Solid PVC foam building formwork |

Vicat softening point | 115℃ can reach 135℃ in the modification plant | 65℃ can reach 80℃ after modification |
The Vicat softening point refers to the deformation temperature. The solid PVC foam building formwork will become soft at 65℃ and the board surface will appear wavy. The softening point of the new hollow plastic formwork is the lowest at 115℃, and there will be no wavy under the high temperature of 115℃ | ||
Difference in structure | Hollow | Solid |
A lot of heat will be emitted during the concrete solidification process. The solid slab conducts heat through the material, and the board will release thermal deformation at high temperatures. The new hollow plastic building formwork is hollow in the middle, and only one side of the board is heated, and the middle is through the flow of air. The other side of the board will not be affected by the heat generated by the concrete solidification | ||
Weight | 14kg | 16kg |
Recovery value | The waste board is USD8.00, the material density is less than water, and the waste board is easy to clean | The raw material is USD5.00/sheet, the density of the material is greater than that of water, and the waste boards are not easy to clean |
The solid PVC foamed building template is low in raw material cost, and the waste boards are not easy to clean, so the recycling value is too low. Generally, manufacturers are not willing to recycle. | ||
Materials | Polypropylene | PVC |
The viscosity of PVC material is too low, and the middle part is easily damaged if the middle part is foamed or filled with wood powder. The new hollow plastic formwork is a whole material with high viscosity, good toughness and no local damage. | ||
Minimum construction temperature | The solid PVC foamed building template will become brittle when the temperature is below 0℃, and the nails at the edge of 1CM will break, and the new hollow plastic formwork will only appear at -20℃. | |
What are the characteristics of hollow plastic formwork?
The new hollow plastic formwork is non-hygroscopic, corrosion-resistant, and acid-resistant, and is especially suitable for use in humid environments; the hollow plastic formwork has high strength, impact resistance, abrasion resistance, long service life, and turnover can reach more than 40 times; the surface of the hollow plastic template is smooth , Smooth and clean, no need to paint release agent, can be sawed, nailed, can be used at the same time with the wooden template; used waste boards and scraps can be recycled and reused, saving costs and reducing pollution.
