Two national standards drafted by eSUN has officially released!

On June 4th

The National Standardization Administration Committee officiallyreleased two national standards drafted by eSUNon the national standard information public service platform: “Polycaprolactone” and “PLAfilament for fused deposition modeling.

eSUN, themedongreen, is committed to the industrialization of environmentally friendly biomaterials. With the business philosophy of “differentiated positioning and open innovation”,eSUNadheres to the combination of independent innovation and open innovation, and has applied more than 40 international and domestic invention patents on the synthesis,modification, application and chemicalrecyclingindustry chainof biomaterials, of which more than 30 have been authorized. It has laid a solid foundation for the development of biodegradable polymer materials and recycling economy.

In addition to its polylactic acid (PLA) industrialization technology, eSUNalso has the world’s leading polycaprolactone (PCL) continuous polymerization technology. The releaseof the current national standard of polycaprolactone (PCL) will promote the application of products and the development of the industry.


Polycaprolactone is a semi-crystalline biodegradable polymer with a white appearance, a melting point of 58-60 ° C, a waxy texture, good flexibility, and low temperature plasticity. Its low temperature viscosity can be used in PUR adhesives, hand molding and 3D low temperature filament applications; PCL products are not irritating to the skin after molding, and are widely used in disposable medical plates, medical bandages, etc. Its a safe and environmentally friendly material.

Product advantages

1. High crystallinity and low melting point, can be molded at low temperature;

2. Excellent adhesion on difficult-to-bond substrates;

3. Good compatibility with a variety of polymers;

4. Easy to dye or color;

5. Non-toxic, biodegradable.

Main application

Surgical field

Surgical sutures, orthopedic splints, radiotherapy plates, resin bandages, dental impressions, etc.;

Polyurethane resin field

Coatings, inks, hot melt adhesives, non-woven adhesives, shoe materials, structural adhesives, etc.;

Film and composite packaging field

Blown film, laminate, etc.;

Other areas

Handmade models, organic colorants, powder coatings, etc.

Based on the synthesis of polylactic acidand polycaprolactonematerials, eSUNhas been conducting research on modification and application of materials, and has mastered the processing technique such asmaterialinjection molding, extrusion, film, fiber, foaming and lamination.


In terms of biomaterials application,eSUNhas been theworld pioneerto expand the application of PLA in 3D printing since 2006, becoming the global leader in FDM3D printing materials, and eSUN3D printingfilamentshas become an internationally renowned brand. In 2015, the company applied for the relevant national standard formulation task, which lasted more than three yearstocomplete, and was officiallyreleased this year, which will effectively promote the healthy development of 3D printed materials!
