PVC is an acronym for polyvinyl chloride. A resin is a material often used in the production of plastics and rubbers. PVC resin is a white powder commonly used to produce thermoplastics.

Other members of the vinyl family can be used for similar applications, but PVC tends to be the most popular member of that family. It is believed to be superior to other options because it can be produced in numerous forms and used to create a wide array of items for many industries. Products made with PVC resin include blood bags, windows, and pipes.

PVC resin alone is a raw material. It can be made into products with a wide range of properties from soft and flexible to light and rigid. The outcome is often determined by additives. Other ingredients must typically be added to convert this resin into a finished product. These can include heat stabilizers, lubricants, and fillers. One of the most common types of additives to be blended with PVC is plasticizers, such as butyl glycolate, epoxy resins, and dialkyl azelates.
