Cyclohexanone, as an important organic synthetic material, plays an important role in the field of degradable plastics. In addition to the production of the current more popular degradable plastic PBAT, there is an important use is the synthesis of another important degradable material polycaprolactone (PCL). Today, we will focus on the performance characteristics of polycaprolactone:Polycaprolactone is the synthesis of ε-caprolactone from cyclohexanone, which is further synthesized by ring-opening polymerization under the action of catalyst. Polycaprolactone is a white opaque solid with certain rigidity. In addition, polycaprolactone has good biodegradability, drug permeability, and can release drugs stably for a long time. Therefore, polycaprolactone is widely used in the production and processing fields of drug carriers, coating toughening, degradable plastics, polyurethane modification, etc.
Performance characteristics of polycaprolactone:
1. Biocompatibility
Polycaprolactone has good compatibility with biological cells, cells can grow normally on its substrate, and can be degraded into CO2 and H2O. Therefore, polycaprolactone can be used as drug sustainedrelease carrier, cosmetic material, vascular stent, surgical sutures, cell and tissue culture medium frame, etc.
2. Biodegradability
Polycaprolactone can be completely decomposed into CO2 and H2O in soil and water environments. However, the current cost is too high, and the application in the field of degradable plastics needs to be developed.
Polycaprolactone has good mechanical properties and can be processed by injection molding, blow molding, molding, extrusion and other molding methods. For the commonly used degradable plastic polylactic acid, polycaprolactone has better hydrophobicity, and polycaprolactone can be applied to plastic film bags, 3D printing supplies and so on.
3, good compatibility with other polymer materials
Polycaprolactone can be well compatible with PE, PP, ABS, AS, PC, PVAC, PVB, PVE, PA, natural rubber and other polymer materials. Therefore, polycaprolactone can be used as plastic low temperature impact property modifier, environmental protection plasticizer, organic coloring agent, hot melt adhesive and so on.
As the main cyclohexanone supplier in China, Shandong Desen Lai Chemical Co., LTD will escort the development of domestic polycaprolactone business.
