The American Architectural Manufacturers Association’s (AAMA) 2018 Fall Conference hosted Sylvia Moore this year, Shintech’s director of technical development. Moore discussed the variety of uses with PVC resins and compounds, along with the importance of PVC sustainability efforts.

“This presentation is geared toward explaining the different attributes of PVC resins and how to evaluate resins coming into the plant,” Moore says. “It’s also about how the different attributes related to finished product quality and how different molecular weights of resins can affect properties and other additives when manufacturing a final PVC product.”

Moore delved into the history of PVC, noting that the material was first developed in 1926 and the first AAMA standard for vinyl doors and windows was created in 1986. She explained the different types of PVC resin, along with a few of their various uses.

Moore also reviewed how different countries make resins, including the U.S., where an ethylene process is utilized, Europe, which uses oil, and Asia (particularly China), which uses both acetylene and ethylene processes.

“[Understanding additives and raw materials is] critical to being a successful manufacturer,” says Moore. “Putting together your formulation is much like baking a cake. PVC is a unique polymer in that you have to add a lot of things to it to get the products you want.”

This is why it is so well liked, she suggests, due to the material’s versatility.

“It can be flexible; it can be rigid; it can be weatherable; it can be put into airplanes,” Moore says. “The ingredients that go into a PVC formulation govern what products can be produced from it.”
