PVC is a type of polymer, and like all polymers, they have different characteristics depending on the type of reactor, average molecular weight, and viscosity. This polymer is in the form of a white powder, which is combined with various additives and is used in common manufacturing methods such as extrusion. Products like pipes, doors, and windows are referred to as UPVC if no plasticizer is used in the formula, and as PVC if plasticizer is included. Several companies use plasticizers to soften the hard PVC before manufacturing their products. PVC is called P-PVC when it has softened. These two have no advantages to each other, they are prepared based on the need and application.
