環保可塑劑高值化產品的開發及應用

鄰苯二甲酸酯類塑化劑具有獨特的優異性，普遍應用於塑化產業的添加助劑，然而該可塑劑具生殖毒性、環境不分解、生物蓄積及有致癌可能性，被疑似為環境賀爾蒙，導致全球許多國家包括台灣都限制其用途與在終端產品中的含量。本研究經由加氫反應將此類原本具毒性的鄰苯二甲酸酯可塑劑轉變成性質相近且無毒的環己烷二羧酸酯環保可塑劑，成為極具開發價值的綠色環保產品。台灣中油公司不僅在實驗室完成此產品的技術開發，更透過自建的試驗工場進行生產，所生產之產品性能可符合規範要求。在產品性能驗證上，將此環保可塑劑與PVC 粉末摻混，可成功製備成塑膠粒、軟管、薄膜與中油寶寶公仔等不同類型之塊材與實體產品，同時中油寶寶公仔已通過SGS 及財團法人台灣玩具暨兒童用品研發中心的檢驗，獲得安全玩具＂ST＂的認證。未來將繼續投入後續研究與其他環保產品的開發，期盼能為國人健康盡一份心力。

Phthalate-based plasticizers have the unique properties and are widely used as the additives in plastics industry. However, Phthalate has reproductive toxicity, environmental disagreement, bioaccumulation and carcinogenic potential. Thus, it is suspected to be environmental hormone. Many countries around the world, including Taiwan limit its usage and content in the end product. In this study, the hydro-treating process is utilized to convert this kind of plasticizer into a similar and non-toxic cyclohexane dicarboxylate environmental friendly plasticizer, which is a very valuable green product to be developed. Currently, CPC Taiwan not only develops the manufacture procedures in laboratory, but also produces it in our self-build pilot plant. All product performance can meet the requirements. To verify the product performance, blending this environmentally friendly plasticizer with PVC powder can successfully manufacture the plastic particles, hoses, films and the CPC action figures so on. Moreover, the CPC action figure pass the test by SGS and Taiwan Children's Commodities R & D center, access to safety toys ＂ST＂ certification. In the future, CPC Corporation will continue the follow-up research and develop other environmentally friendly products to make an effort for human health.
