PCL is a synthetic, semi-crystalline polyester that has a low melting point and high flexibility. It is widely used in the production of specialty polyurethanes, drug delivery systems, absorbable surgical sutures, nerve guides, and tissue engineering scaffolds.

Our PCL is medical grade, which means it meets the strict standards of safety and performance for implantable devices. It is also customizable, so you can choose the end group and molecular weight that suit your needs. Whether you need a linear, branched, or star-shaped PCL, we can synthesize it for you with high precision and efficiency.

We know that PCL is not easy to synthesize and can be expensive, but we have a solution for that. We use a novel ring-opening polymerization method that reduces the cost and time of production, while maintaining the quality and purity of the polymer. This means you can get more PCL for less money and faster delivery.

FAQs

PCL is a synthetic, semi-crystalline, biodegradable polyester with a low melting point of around 60°C and a glass transition temperature of about −60°C. It can be prepared by ring opening polymerization of ε-caprolactone using a catalyst such as stannous octoate.

PCL is widely used in the production of specialty polyurethanes, drug delivery systems, absorbable surgical sutures, nerve guides, and tissue engineering scaffolds. It is also used as an additive for resins, a polymeric plasticizer for PVC, and a feedstock for prototyping systems such as 3D printers.

PCL has good resistance to water, oil, solvent and chlorine, high flexibility, low toxicity, and excellent biocompatibility and biodegradability. It is especially suitable for long-term implantable devices and controlled drug release applications.

PCL has a slow degradation rate, poor mechanical properties, and low cell adhesion compared to other biopolymers. It also suffers from thermal degradation and oxidation during processing and storage. To overcome these drawbacks, PCL can be blended or copolymerized with other materials, such as starch, calcium phosphate, bioactive glass, etc.

 You can order PCL from us by contacting us through our website or email. We offer PCL with medical grade, custom end group and molecular weight, and competitive price.
