Elastomeric alloys of PVC

The performance standards for flexible PVC compounds continue to become more demanding as manufacturers pursue more value‐added applications traditionally dominated by rubbers and thermoplastic elastomers. Blending of PVC with other polymers has proven to be a viable approach in developing higher performance flexible PVC‐based materials. This paper will review some of the typical approaches to producing PVC‐based elastomers, and show how these standard flexible PVC blends compare to a newly developed family of PVC alloys. The advantages of these materials will be discussed, and some examples of commercial materials and their application will also be reviewed.
