It’s all vinyl chloride polymerization; the only difference is the source of the vinyl chloride.
Ethylene-based PVC is mainly used for profiles, as well as transparent sheets and films, while calcium carbide-based PVC is primarily used for pipes. However, the quality of PVC produced by the calcium carbide method has improved significantly nowadays, and many profile manufacturers are using PVC made through this method.

There shouldn’t be a big difference; it’s just that the manufacturing process is different
The end products are the same; it’s only the production process that differs
