Polyvinyl resins

Abstract

Polyvinyls are not sensitizers. Some additives of polyvinyl resins are highly sensitizing: phthalates, maleates, benzophenones, epoxy resins, etc. Diagnostic procedures include patch-testing with vinylic resins and additives used in the polymerization process. Polyvinyl chloride (PVC) always contains free molecules of vinyl chloride that can induce allergic contact dermatitis, contact urticaria, Raynaud’s syndrome, and systemic sclerosis. PVC powder has irritating properties. Incineration of PVC objects releases dioxin and Hcl, posing hazard to skin and mucosa. Polyvinyl resins have multiple uses including medical purposes.
