unplasticized
Without added plasticizers
Unplasticized describes a material, typically PVC (polyvinyl chloride), that hasn't been softened with plasticizers.
Without these additives, the material remains rigid and hard rather than flexible.
Unplasticized PVC (often abbreviated uPVC or UPVC) is the standard material for window frames, pipes, and siding because it resists weathering better than the softened version.
