The difference between uPVC and PVC items and pipes also extends to the properties. Plasticizers are used in PVC pipes, and phthalates are among the most common. This, and other plasticizers, are a type of odorless and colorless ester. When put into PVC, they work to make the pipes that are produced more bendable and flexible by enhancing the overall flexibility. uPVC is free from plasticizers. uPVC is also free from BPA where PVC contains it.
