What is Poly(ε-Caprolactone)?

Poly(ε-Caprolactone) (English: polycaprolactone, described as PCL) is a semi-crystalline polymer, a chemically synthesized biodegradable polymer product, its structural repeating device has 5 non-polar methylene-CH2 starch, and so on. Substance mixing can make totally biodegradable products.

Poly(ε-Caprolactone) Properties:

Melting point 60 °C(lit.)
density 1.146 g/mL at 25 °C
storage temp. -20°C
form pellets


Poly(ε-Caprolactone) Application

In resin modification
It can be used to improve the flexibility, low temperature impact resistance, fluidity and formability of acrylic, polyester, vinyl and other resins.

It is used as a modifier for automotive primers, intermediate coatings and surface coatings, as well as solvents for various building materials and latex coatings. density.

When applied to microencapsulated pharmaceutical preparations, the microencapsulated pharmaceutical preparations have the effects of reducing drug toxicity and side effects, preventing drug inactivation, reducing the number of times of taking medicines and targeting drug delivery. It is also used in controlled release drug carriers, cells, and tissue culture scaffolds.

Polyurethane adhesives made with Poly(ε-Caprolactone) polyols have better adhesion than those produced with other polyethers and polyesters, and have better color, hydrolytic stability and uniformity. Also has better peel strength.

in polyurethane elastomers
Compared with ordinary polyol synthetic PU leather (artificial leather), PCL has better resistance to heat aging, light aging and water aging.

It can synthesize water-based polyurethane with polyether, etc., the coating film is relatively soft, resistant to ironing, dry and wet rubbing, and solvent resistance. It is suitable for bottom and middle layer finishing of dual-purpose leather such as garment leather.

Raw materials
Used as oligomers and modifiers, it can not only improve toughness, but also improve low-temperature properties, and functional properties such as reactivity are also greatly improved.

Biodegradable Material Poly(ε-Caprolactone)

Poly(ε-Caprolactone) has good biodegradability, drug permeability, and can release drugs stably for a long time. Therefore, PCL is widely used in drug carriers, plasticizers, degradable plastics, nanofiber spinning, and molding materials. production and processing.

Poly(ε-Caprolactone) has good compatibility with biological cells, cells can grow normally on its scaffold, and can be degraded into CO2 and H2O.

Therefore, Poly(ε-Caprolactone) can be used in drug sustained release carriers, cosmetic materials, vascular stents, surgical sutures, cell tissue culture racks, etc.

Poly(ε-Caprolactone) can be completely decomposed into CO2 and H2O from June to December 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.

Poly(ε-Caprolactone) 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, PCL has better hydrophobicity.

Poly(ε-Caprolactone) can be applied to plastic film bags, 3D printing consumables, shoe materials, etc.

Poly(ε-Caprolactone) can be well compatible with PE, PP, ABS, AS, PC, PVAC, PVB, PVE, PA, natural rubber and other polymer materials.

Therefore, Poly(ε-Caprolactone) can be used as plastic low temperature impact performance modifier, plasticizer, organic colorant, hot melt adhesive, etc.

Poly(ε-Caprolactone) has a high degree of crystallinity, so the degradation rate is slow. With a Tg of -60°C, it is very soft and has great extensibility; its melting point is 60-63°C and it can be molded at low temperature.

Therefore, Poly(ε-Caprolactone) has high safety and is usually used for 3D printing pen consumables for children.

Poly(ε-Caprolactone) Market Prospects

Due to the advancement of the plastic restriction order, the bio-based degradable material PLA, which has been widely used in the field of biodegradable films, has been increasing in price with the tight market supply. According to market feedback, due to supply and cost considerations, some companies in the biodegradable film industry have begun to look for other biodegradable materials to partially replace PLA for production use. Among these materials, Poly(ε-Caprolactone) and PBAT, as two kinds of polymer materials with good toughness, can exert their own characteristics in the field of biodegradable membranes.
Poly(ε-Caprolactone) and PBAT are blended and modified to be used in the field of fully degradable films, and have good application prospects. Among them, Poly(ε-Caprolactone) can endow this blended modified film with better functionality, as follows:

1). Improve heat sealing performance
Poly(ε-Caprolactone) has high crystallinity and low melting point, which can make the film sticky without too high activation temperature, which is beneficial to improve the heat sealability of the film material. This good characteristic is expected to make PCL widely used as a heat-sealable functional layer in supermarket shopping bags, environmentally friendly packaging materials, protective film substrates, etc.;

2). Stiffness and toughness are unified
Poly(ε-Caprolactone) material has a unique shape memory function, which can effectively reduce the occurrence of material creases after multiple bending;

3). Good processing performance
The blending of Poly(ε-Caprolactone) and PBAT can significantly reduce the processing temperature of the material and reduce energy consumption;

4). Good degradability
Poly(ε-Caprolactone) is not only suitable for home composting, but also suitable for seawater degradation environments.

In addition, when Poly(ε-Caprolactone) is used in the blending system with PBAT, it can also improve the transparency and low temperature resistance of the film.
