Here is the difference between PVC and UPVC.
At first glance it may seem that there is a slight difference between UPVC and PVC, PVC (polyvinyl chloride) pipe is ordinary, physically strong but lightweight and has plastic properties and is flexible. PVC is non-plastic polyvinyl chloride, in fact UPVC is the same PVC that has become non-plastic and hardened, and this product is called UPVC in the United States and has been renamed PVCU in Europe since 1980. Both are plastic pipes and are widely used in construction. Beyond surface similarities, the two types of pipes are produced differently and therefore have different properties and slightly different applications in construction and other industrial processes.
