PCL (Medical Grade)
PCL has excellent biocompatibility, memory, biodegradability, etc. It is widely used in various fields. Polycaprolactone is soft, easy to process, and has excellent performance, which can be used as medical materials for humanbody. Polycaprolactone has strong crystallinity and slow degradation.
Its degradation in vivo can be divided into two stages: the first stage shows that the molecular weight decreases continuously without deformation and weight loss; The second stage refers to that after the molecular weight decreases to a certain value, the material begins to lose weight and is gradually absorbed and excreted by the body.

Surgical suture, orthopedic splint, radiotherapy plate, resin bandage, dental impression, etc.
