Description

Poly(vinyl chloride) (PVC) is one of the most widely used polymers in the world. This polymer is usually plasticized with low or medium molecular weight materials such as dioctyl phthalate, trioctyl phosphate, and poly(propylene glycol) esters. The properties can be finely tuned from rigid to soft and flexible by varying the plasticizer content from a few percent to more than 60%. The largest use is for rigid pipe; other uses include window frames, flooring, cable insulation, and other household and construction applications.
