[0002] Plasticizers are indispensable additives in the plastics industry, their core function being to increase the flexibility, ductility, and processability of polymers. Traditionally, phthalate plasticizers (such as DOP and DBP) have been widely used due to their excellent overall performance and low cost. However, with the increasing global awareness of environmental protection and health, studies have shown that these plasticizers have potential carcinogenic, mutagenic, and endocrine-disrupting effects, leading to strict restrictions on their application in medical devices, food packaging, and children's toys. Against this backdrop, the development of environmentally friendly, non-toxic, and biosafety-friendly non-phthalate plasticizers has become an inevitable trend in the industry.
