Polycaprolactone (PCL) is a semi crystalline polymer, which is a chemically synthesized biochemicalbook degradable polymer. Its structural repeating unit is blended with five nonpolar methylene CH2 starch and other substances to produce a complete biodegradable material.The melting point of polycaprolactone is 59 to 64�°C, and the glass transition temperature is -60�°C. Low molecular weight, colorless crystalline solid with waxy texture. At the same time, it has good biocompatibility, biodegradability, compatibility, high crystallinity and low melting point.

Application:
A biodegradable polymer, non-toxic, biodegradable in soil, excellent mixing, mechanical compatibility with many polymers and good viscosity to many matrices. Extrusion aids, mold lubricants, release agents, pigment and filler dispersing aids, and polyester segments in polyurethane and block polyester.
