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

聚己内酯（PCL）是一种可生物降解的半结晶聚酯，用于组织工程和药物递送研究应用。由于脂肪族链的长度增加，聚己内酯的降解速度明显慢于其他常见的可生物降解聚合物，如聚乳酸。PCL具有较低的熔点（55-60℃），非常适合热处理，并增加了其在3D生物打印等新应用中的使用。除了良好的热性能，PCL还具有在有机溶剂中的高溶解度，允许多种其他加工选择。该产品具有低残留水、单体和催化剂（锡）的特点，是组织工程和3D生物打印研究的理想选择。

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.
