Polycaprolactone (PCL) is a semi crystalline hydrophobic biodegradable polyester which finds major applications as a drug delivery agent because of its cost efficiency, high toughness and biocompatibility. PCL possesses some unique properties such as:
• It degrades slower than other biodegradable polyesters in physiological condition, this property can be exploited in the controlled release of drugs in target tissues over a period of time.
• Its poor surface wetting and interaction with biological fluids on account of its hydrophobicity leads to poor cell adhesion and proliferation, hence it is blended with other synthetic /natural polymers.

Polycaprolactone is a polyester type polymer having a melting point of about 60ºC, and a glass transition temperature of -60ºC (practical MW is generally between 3000 and 90000 g/mol).
Below its melting point its mechanical resistance is very good, and depending on the degree of ordering of its polymer chains (crystallization) can be as high as that of polyethylene. In addition, the polymer presents high biocompatibility and high biodegradability.

Polycaprolactone can easily be shaped into any form after melting in hot water.
