Products Description
PCL(CAS 24980-41-4) is a biodegradable aliphatic polyester that is synthesized from ε-caprolactone monomer through ring-opening polymerization (ROP). It is a widely used degradable material.
PCL has the characteristics of low melting point, non-toxicity, good ductility, easy processing, superior biodegradability, biocompatibility and memory. It has been widely applied in many fields (especially in the medical field), such as bandages, drug delivery, bone graft replacement and tissue engineering (such as cartilage, bone, tendon, blood vessel, skin and nerve).

FAQ
Q1:What does shape-memory property of PCL mean?
Re: It can be reshaped when heated near its melting point (~60℃) and keeps the shape after cooling. It will return to its original preset shape upon re-heating, commonly used for low-temperature medical splints and rehabilitation braces.
Q2:Could PCL be used for 3D-printed implants?
Re:Yes, PCL has been used in the research and clinical practice of 3D-printed implants.
Q3:How to select the PCL brand with different molecular weights (Mn)?
Re: The higher the molecular weight, the greater the melt viscosity, the higher the processing temperature, and the slower the degradation; the lower the molecular weight, the often higher the crystallinity and greater the hardness, but the degradation behavior is more complex (affected by both crystallinity and morphology).
Q4: How long is the delivery cycle?
Re: Small batch orders will be shipped within 1-3 working days after payment; large batch orders will be shipped within 3-7 working days after payment.
