Abstract: Described are rigid and semi-rigid polyvinyl chloride (PVC) films, layers, or sheets, and methods of forming the same. The PVC products includes polyvinyl chloride resin and at least one 2D filler incorporated at the micro- or nano-scale. The film can have a low water permeance, for example, lower than that of a traditional PVC film. The water permeance of the PVC film described in this invention is significantly lower than that of a PVC film specifically developed for pipe jacketing applications. Standard pipe jacketing applications use either PVC or metal jacketing in their systems. The invention described herein produces a finished PVC product with a low water permeance similar to that of the metal jacketing products specifically developed for pipe jacketing applications.
