1. The materials are different. The solid is made of PVC and the hollow is made of PP.
2. Same size, different weight. For example, 2440 * 1220 * 18mm, PVC solid is about 37kg, and PP hollow is about 28kg
3. Prices are different. In terms of weight price, PP hollow is higher than PVC, because the local price of PP plastic is higher than PVC. You can compare the price with the above weight.
4. In terms of rigidity, PVC solid is better than PP hollow. In other words, PVC stiffness is better and it is not easy to bend.
5. In terms of toughness, PP hollow is better than PVC solid, because PP polypropylene has natural flexibility, is not easy to break, but is easy to bend.
6. With the same size and weight per unit area, PP is lighter than PVC, which saves labor in construction. However, hollow holes are very easy to grout, which makes the formwork heavier and harder to clean and maintain. On the contrary, PVC is relatively heavy and the construction process is relatively laborious, but the solid structure is easy to clean and maintain.
7. Whether PVC is solid or PP is hollow, its production process, use method and function are the same as those of traditional wood templates or plywood, just the material is different.
8. In terms of use times, PVC solid and PP hollow can be used 50 times on average. The key is maintenance, environment and workers' care.
9. For us, our market comparison is about 80% PVC solid VS 20% PP hollow. (This data is based on customer feedback.)
10. PVC solid formwork is flame retardant, PP hollow is not.
11. PVC solid formwork does not deform under high temperature, and PP hollow formwork is worse in this respect.
