Product Introduction:
Polycaprolactone (PCL for short) is a polymer material with unique properties and wide applications. It is a polyester polymer compound synthesized by ring-opening polymerization of ε-caprolactone monomer under the catalysis of metal anion complex catalyst. Its molecular structure contains 5 non-polar methylene groups (—CH₂—) and a polar ester group (—COO—), which gives it good flexibility and biocompatibility.
Polycaprolactone is a semi-crystalline polymer with a low melting point, usually between 59°C and 64°C, and a glass transition temperature of about -60°C. Due to its low melting point and high crystallinity, it can be molded at lower temperatures, which gives it a significant advantage in industrial production.
One of the most prominent properties of polycaprolactone is its biodegradability. In the natural environment, it can be decomposed by microorganisms or enzymes, and the final products are carbon dioxide and water, which makes it an environmentally friendly material. In addition, it has good biocompatibility, which means that it does not cause significant toxicity or irritation in the body, and cells can grow normally on its scaffold.
Therefore, Polycaprolactone has been widely used in the medical field, such as as a drug carrier, tissue engineering scaffold, degradable suture, etc. Polycaprolactone also has shape memory function, which can deform under external force and return to its original shape under external conditions such as heating. This feature makes it also have potential application value in the field of smart materials.
Polycaprolactone has excellent processing performance and can be molded by a variety of methods, such as extrusion, injection molding, blow molding, solution spin coating, etc. It can be blended with other materials to improve its performance and function. For example, it can be blended with materials such as polylactic acid (PLA), gelatin, hydroxyapatite, etc. to prepare composite materials with specific properties.

Medical field
In the medical field, Polycaprolactone is widely used. It is used as a drug sustained-release carrier, which can encapsulate drugs in a polymer matrix. By adjusting the composition and structure of the polymer, it can achieve slow release of drugs, prolong the drug’s action time, and reduce the frequency of administration. In addition, PCL is also used to manufacture tissue engineering scaffolds. Its flexibility and processability enable it to be made into scaffold materials of various shapes, providing a good growth environment for cells and promoting tissue repair and regeneration. The absorbable sutures made of PCL can gradually degrade in the body, avoiding the trouble of traditional sutures requiring secondary surgery to remove, reducing the patient’s pain and infection risk. In addition, PCL can also be used to manufacture medical devices such as artificial joints and vascular stents. Its mechanical properties and biocompatibility can meet the use requirements of human joints.
Packaging field
Polycaprolactone has broad application prospects in the packaging field. As a biodegradable material, PCL can effectively reduce the pollution of packaging waste to the environment. PCL packaging materials can effectively isolate external oxygen, moisture and microorganisms, maintain the freshness and quality of food, and are therefore widely used in food packaging. In addition, PCL is also used in pharmaceutical packaging, which can protect drugs from the influence of the external environment and ensure the stability and safety of drugs. The degradability of PCL packaging materials also meets environmental protection requirements, making it widely used in daily necessities packaging, such as for packaging cosmetics, shampoo, shower gel, etc.
Agricultural field
Polycaprolactone also has important applications in the agricultural field. PCL mulch can effectively maintain soil moisture, increase soil temperature, and promote crop growth. Compared with traditional plastic mulch, PCL mulch can be naturally degraded after use, avoiding the pollution of soil by traditional mulch residues. In addition, PCL can also be used to make seed coating materials, provide necessary nutrition and protection for seeds, and improve seed germination rate and growth quality. Its degradability reduces pollution to the environment and meets the requirements of sustainable agricultural development.
Materials Science and Engineering
In the field of materials science and engineering, the application of Polycaprolactone is mainly reflected in its good processing performance and versatility. PCL is an ideal 3D printing material that can be made into filaments for the manufacture of various complex structures and models. In addition, PCL fibers are soft and comfortable, elastic and biodegradable, and can be used to manufacture high-end textiles and clothing. PCL can also be blended or compounded with other materials to prepare composite materials with special properties. For example, PCL and hydroxyapatite can be blended to make bone repair materials, further expanding its application range in the field of materials science.
Other fields
Polycaprolactone has also been used in some other fields. In the field of coatings, PCL, as a basic material or additive for coatings, can improve the performance and quality of coatings and broaden the application range of coatings. In addition, PCL has shape memory function, which can deform under external force and return to its original shape under external conditions such as heating. This feature makes it have potential application value in the field of smart materials, such as for the manufacture of deformable smart devices.
1. Biocompatibility and Biodegradability
Polycaprolactone offers excellent biocompatibility; cells can grow normally on its scaffold without experiencing significant toxic or irritating reactions. In addition, PCL can be decomposed in its natural environment through microorganisms or enzymes and breakdown into carbon dioxide and water as byproducts – making it an environmentally-friendly material which makes it perfect for medical and packaging fields.
2. Low Melting Point and High Crystallinity
Polycaprolactone has an ideal melting point range between 59degC and 64degC, with a glass transition temperature near -60degC. This low melting point enables PCL to be processed at lower temperatures – cutting energy consumption and processing costs considerably while creating opportunities to lower energy consumption in production lines. At the same time, PCL exhibits superior crystallinity properties such as creating rubber states at physiological temperatures, offering impressive viscoelastic properties.
3. Superior Processing Performance
Polycaprolactone can be easily processed using various techniques such as extrusion, injection molding, blow molding and solution spin coating. Thanks to its exceptional processing performance it can be formed into various forms including fibers, flakes and sheets which make it perfect for manufacturing surgical sutures, medical equipment and 3D printing materials.
4. Excellent Compatibility and Solubility
Polycaprolactone has excellent compatibility with various polymer materials (PE, PP, ABS and PC among others), which allows it to improve performance through blending or copolymerization. Furthermore, PCL exhibits good solubility in aromatic compounds, ketones and polar solvents further broadening its application range.
5. Customizable Degradation Rate
Polycaprolactone’s degradation rate can be easily customized through modification of its molecular weight and composition, providing it with the versatility required to meet various application scenarios – for instance long-term drug release in sustained-release systems. This customizability ensures it can meet this need while meeting different user needs in terms of drug release stability and release over time.
6. Economic and Sustainable
PCL offers economic and sustainable advantages when used for manufacturing purposes, thanks to its lower production costs and biodegradability that reduces pollution to the environment. These characteristics make PCL an excellent environmental-protection choice when replacing traditional non-degradable plastics.
