설명

일반 설명

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.

We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This is an enabling product that belongs to a family of high-performance bio-based polymers that are essential for developing efficient, low-cost, and environmentally friendly renewable energy solutions.

애플리케이션

• PCL loaded with antibiotics may be used to treat infections of the respiratory tract, like tuberculosis.
• Investigations were carried out based upon phenotypic responses of human bone marrow mesenchymal cells (hBMSCs) for different ratio of chitosan/ polycaprolactone (PCL) blends.
• PCL/biomedical ceramic materials have been studied for possible osteo tissue regeneration.
• Action of PCL/graded insulin/beta-5 glycerophosphate concentrations on osteochondral tissue formation through adipose-derived stromal cell differentiation.
• Other general uses include:extrusion aid, die lubricant, mold release, pigment and filler dispersion aid and polyester segments in urethanes and block polyesters.
