中文名稱：聚己內酯、2-氧雜環庚烷酮均聚物、聚已酸內酯、聚己內酯多元醇

英文名稱：polycaprolactone、aquaplast,caprolactone、2-Oxepanone,homopolymer

聚己內酯（PCL）是一種可生物降解的半結晶聚酯，用于組織工程和藥物遞送研究應用。由于脂肪族鏈的長度增加，聚己內酯的降解速度明顯慢于其他常見的可生物降解聚合物，如聚乳酸。PCL具有較低的熔點（55-60℃），非常適合熱處理，并增加了其在3D生物打印等新應用中的使用。除了良好的熱性能，PCL還具有在有機溶劑中的高溶解度，允許多種其他加工選擇。該產品具有低殘留水、單體和催化劑（錫）的特點，是組織工程和3D生物打印研究的理想選擇。

Polycaprolactone (PCL) is a biodegradable, semicrystalline polyester for use in tissue engineering and drug delivery research applications. Due to the increased length of the aliphatic chain, polycaprolactone degrades significantly slower than other common biodegradable polymers, such as polylactide. PCL features a low melting point (55-60 °C), making it ideal for thermal processing and increasing its use in novel applications such as 3D bioprinting. In addition to its favorable thermal properties, PCL also features high solubility in organic solvent allowing for a multitude of other processing options. This product features low residual water, monomer, and catalyst (tin) making it an ideal choice for use in tissue engineering and 3D bioprinting research.
