Polycaprolactone (PCL), also known as Poly(ε-caprolactone) , is produced by ε- Caprolactone is a polymerized polyester formed by ring opening polymerization under the conditions of metal organic compounds as catalysts and dihydroxy or trihydroxy groups as initiators. Its molecular weight and degree of disproportionation vary with the type and amount of starting material used.
Polycaprolactone (PCL) is a kind of semi-crystalline polymer, which is a kind of biodegradable material of biochemicalbook. PCL has five non-polar methylene CH2 starch and other substances on its structural repeating unit, which can be prepared completely biodegradable material.

The PCL produced by Uli ECO currently has powder, particle, and microsphere appearances. We have medical grade, industrial grade. We have regular 60,000-molecular weight , 80,000-molecular weight , and of course we can customize some lower/higher molecular weight. We have 100 mesh, 60 mesh, 30 mesh and other different particle sizes. The annual output of raw materials is 50,000 tons.

1. PCL can be used for drug sustained-release carriers, cosmetic materials, vascular stents, surgical sutures, cell tissue culture media, etc
2. PCL can be applied to plastic film bags, 3D printing consumables, shoe materials, etc
3. PCL is not only suitable for household composting, but also for seawater degradation environments.
4. PCL and PBAT blending modification, applied in the field of fully degradable films
5. PCL can also be used for coatings, inks, hot melt adhesives, non-woven fabrics, adhesives, shoe materials, structural adhesives, etc.



Features and Benefits

1. Biocompatibility
PCL has good compatibility with biological cells in the body, and cells can grow normally on its scaffold and degrade into CO2 and H2O.
2. Biodegradability
In soil and water environments, pcl can be completely decomposed into CO2 and H2O from June to December.
3. Good compatibility
PCL can be well compatible with PE, PP, ABS, AS, PC, PVAC, PVB, PVE, PA, natural rubber, etc.
4. Good solvent solubility
PCL dissolves well in aromatic compounds, ketones, and polar solvents, but is insoluble in n-hexane.
5. High crystallinity and low melting point
Very soft, with great stretchability; Its melting point is 60-63 ° C (melting points of 60, 70, 80, optional), which can be formed at low temperatures.
