What is polycaprolactone?

Polycaprolactone (PCL, CAS number: 24980-41-4), also known as polyε-caprolactone, is a polymeric organic polymer formed by ring-opening polymerization of ε-caprolactone monomer under the catalysis of metal anionic complex catalyst, by controlling polymerization conditions, different molecular weight can be obtained. PCL appearance is white solid powder, non-toxic, insoluble in water, easily soluble in a variety of polar organic solvents. PCL has good biocompatibility, good organic polymer compatibility, and good biodegradability, can be used as a cell growth support material, can be compatible with a variety of conventional plastics, and can be completely degraded in 6-12 months in the natural environment. In addition, PCL also has good shape memory temperature control properties, and is widely used in the production and processing of drug carriers, plasticizers, degradable plastics, nanofiber spinning, and shaping materials.

What is polycaprolactone used for?

Medical device field

Polycaprolactone is a commonly used biodegradable material and has been widely used in the field of medical devices. For example, bone repair materials made of polycaprolactone, drug slow-release materials, biological scaffolds and artificial joints all have good biocompatibility and biodegradability. Surgical fields: surgical sutures, orthopedic splints, radiotherapy plates, resin bandages, imprinting molds, etc.

Food packaging

Polycaprolactone can be used to make food packaging materials. This material has excellent physical properties and chemical stability, can be used as plastic wrap, food bags and other materials. Compared with traditional plastic packaging materials, food packaging materials made of polycaprolactone are not only safe and environmentally friendly, but also have excellent heat resistance and cold resistance. Blow molded film, laminate material, composite packaging material, etc.

Textiles

Polycaprolactone can be used in the textile field, and the addition of polycaprolactone in the textile manufacturing process can improve the softness and durability of the fiber. In addition, polycaprolactone can also be used in the manufacture of specialty fabrics, such as waterproof, breathable and protective fabrics.

Paint field

Polycaprolactone has also been widely used in the field of coatings. Polycaprolactone has good gloss, heat resistance and weather resistance, and can be used to manufacture high-performance coatings. In addition, polycaprolactone can also be used to manufacture environmentally friendly coatings, which will not pollute the environment.

Other areas

3D printing materials, hand-made models, organic colorants, powder coatings, etc. PUR hot melt adhesive, ink, non-woven binder, shoe material, structural adhesive, etc.

Packaging, transportation and storage

The product uses special 25kg/ net paper bag; 25kg mesh paper bag on 1000kg tray.

During transportation, it is necessary to prevent rain, collision, packaging damage, leakage and pollution, and must comply with the relevant regulations of the transportation department.

After opening the package, use it as soon as possible. Store it in a cool place, waterproof and moisture-proof, and avoid contact with air and direct sunlight.

As a kind of polymer material with excellent biocompatibility, biodegradability and physical and chemical properties, PCL has been widely used in the fields of medical equipment, food packaging, textiles and coatings. In the future, with people’s attention to environmental protection, health and sustainable development, the application prospect of polycaprolactone will be broader.
