Developing new plastic economy | An article on Esun's sustainable development layout and planning.


With the emergence of global warming and other phenomena, since 2020, the development of low-carbon economy to promote sustainable development has become a global consensus.




The symbol of sustainable development is the sustainable use of resources and a good ecological environment.


Plastics was once hailed as the greatest invention of the 20th century, but times have changed. The development and utilization of plastics over the years have caused huge "white pollution" , this has a serious impact on the climate environment, soil environment and marine environment.


In 2020, the concepts of carbon peak and carbon neutrality were proposed. Global Plastic production and incineration is forecast to emit 56bn tonnes of Carbon dioxide equivalent by 2050, which account 10-13 % of the total carbon budget that could be "spent" by the middle of the century. By the end of the century, plastic-related carbon emissions could account for half of the total carbon budget.


The importance of restricting plastic products is self-evident. Many countries and regions, including China, have adopted legislation to ban plastic products, promote the application of environmental protection materials, develop new plastic economy and promote sustainable development.


At present, the main biodegradable materials on the market mainly include PLA, PBAT, PBS, PCL, Pha and so on. eSUN is mainly based on the synthesis of PLA and PCL, modified, expanded many high value-added or low-cost applications.



  • High value-added applications of eSUN biomaterials in biomedicine


Biodegradable medical materials are Biocompatibility, extremely stable, and easy to process. Aliphatic polyester polymers (polylactide PLA , polyglycolide PGA, polycaprolactone ε-PCL) and their copolymers are the most widely used. eSUN's self-produced PCL can be used in the manufacture of orthopaedic fixation materials and surgical suture, etc .


01 Orthopedic fixation material


Esun’s low temperature thermoplastics can be used as a healing splint material, a patient immobilization system in radiation oncology, orthoses and denture thermoplastic.


Product characteristics:

①Strong support, long-term wear will not fall off or break;

②It has good shape memory function and tensile resistance;

③Smooth surface, no fingerprints;

④Non-latex and biodegradable.

02 Surgical suture


Most absorbable surgical suture are made from PLA and PGA ,and they are fully degraded and absorbed within 2-6 weeks.


In orthopaedic surgery, because the healing time of the medial bone is 3-6 months or longer, sutures of the soft tissue attached to the bone require a full rate of degradation. The sutures produced by PCL spinning can meet this requirement.



  • High value-added applications of eSUN biomaterials in 3D printing




Characteristics of biodegradable 3D printing materials:

①100% bio-based, in compliance with EN 13432 and ASTM D6400. In a composting environment, it completely decomposes into carbon dioxide and water. Non-toxic and harmless to human body, biology and environment.

②Designed by the characteristics of FDM 3D printing filaments, the performance is flexible and not brittle. The product is cost-effective.

③Standard color matching, stable color and lustre. It can be made in more than 20 different colors according to customers' requirements. You can use it immediately after buying.

④On the basis of the pure PLA, the toughness of the material is greatly improved, the lines are not easy to break, the printing is smooth, the finished product is beautiful in appearance, no warping edge cracking and other problems.


Since eSUN entered the 3D printing industry in 2006, in more than 10 years, eSUN has brought a lot of positive changes to the industry through a number of innovative initiatives, effectively promoting the progress and upgrading of the industry, but also contribute to the development of 3D printing applications. So far, eSUN has developed nearly 100 kinds of 3D printing filaments with mature performance and excellent appearance, and its products are well-known all over the world.





High value-added applications of eSUN biomaterials in ecological textile


POLYLACTIC ACID (PLA) is a new biodegradable material, which is made of starch from renewable plant resources (such as corn) . It is safe, sanitary, environmental friendly, with good mechanical and physical properties. Polylactic acid is also the only biodegradable plastic with excellent antimicrobial and mildew resistance.


As a thermoplastic fiber-grade Resin, fiber-grade PLA is used in the form of particles for extrusion into mechanically stretched staple fibers using conventional fiber spinning and drawing equipment. It has excellent colorability and can be used in a variety of printing methods.

With the international and domestic restrictions on plastic changes in the situation, biodegradable materials in dormancy after many years finally ushered in the  "spring " of the development. Experts predict that by 2005, China's total consumption of biodegradable plastic will increase by 430% compared with 2019, based on the banned plastic products policy announced so far in China.


The market development prospects are broad, but in the early industrial growth, due to a variety of irrational factors, there may be "market chaos" situation. When all gradually return to reason, the industry will continue to send out a strong vitality, in each subdivided areas have unlimited development potential.
