Abstract
Polyvinyl chloride (PVC) is among the top three most widely used plastics globally. Di(2-ethylhexyl) phthalate (DEHP) is often added as a plasticizer by up to 40 wt% to impart flexibility. DEHP, a toxin and carcinogen, can leach into the atmosphere to cause environmental contamination. This study investigates the suitability of epoxidized safflower oil, namely Carthamus tinctorius oil (ECTO), as a PVC plasticizer. PVC films with DEHP and ECTO were compared in resilience, elastic modulus, toughness, and glass transition temperature. ECTO films displayed statistically similar physical properties of resilience, elastic modulus, and toughness at up to 30 wt%. ECTO films of 0 to 40 wt% all displayed significantly lower glass transition temperature.
期刊介绍：
The Journal of Elastomers and Plastics is a high quality peer-reviewed journal which publishes original research on the development and marketing of elastomers and plastics and the area in between where the characteristics of both extremes are apparent. The journal covers: advances in chemistry, processing, properties and applications; new information on thermoplastic elastomers, reinforced elastomers, natural rubbers, blends and alloys, and fillers and additives.
