this paper provides a detailed investigation into the effects of trioctyl trimellitate (totm) plasticizer levels on the hardness of polyvinyl chloride (pvc) materials.

the impact of plasticizer levels in hardening pvc plastic,two distinct types of pvc: flexible pvc, which contains a plasticizer, and rigid pvc, which does not. the findings underscore the importance of plasticizers in material design and engineering, offering valuable insights for future applications. keywords: trioctyl trimellitate (totm); polyvinyl chloride (pvc) hardness; plasticizer 1. introduction
