PBSA is a degradable plastic with excellent performance and huge market development potential.
PBSA (polybutylene succinate-adipate) is a degradable plastic that is generally made from fossil resources. It can be degraded by microorganisms in the natural environment. The decomposition rate in 180 days under composting conditions is higher than 90%. PBSA is currently one of the most enthusiastic categories of biodegradable plastics in terms of research and application.
With economic growth and improvement in living standards, the global use of plastic products continues to increase, especially the demand for packaging plastics. This has led to the continuous growth of global waste plastics, causing great harm to the ecological environment. Our country is a major producer and marketer of plastics. In order to achieve sustainable development, our government has vigorously promoted the development of the degradable plastics industry. In January 2020, the National Development and Reform Commission and the Ministry of Ecology and Environment issued the “Opinions on Further Strengthening the Control of Plastic Pollution”, banning and restricting non-degradable plastics from production, sales, use and other aspects, which is known as the “most stringent” plastic restriction in history. This order is beneficial to the development of my country’s degradable plastics industry.
Degradable plastics include biodegradable plastics and petroleum-based degradable plastics. Among petroleum-based degradable plastics, dibasic acid glycol polyesters are the main products, including PBS, PBAT, PBSA, etc., using butyl It is prepared from diacid, butylene glycol, etc. as raw materials. This type of product has the advantages of good heat resistance, easy availability of raw materials, and mature technology. Compared with PBS and PBAT, PBSA has a low melting point, high fluidity, fast crystallization, excellent toughness, and degrades faster in the natural environment.
According to the “PBSA Industry In-depth Market Research and Investment Strategy Suggestions Report 2022-2026” released by the Industrial Research Center, PBSA can be used for Packaging, daily necessities, agricultural films, medical materials, 3D printing materials and other fields. The problem of white pollution is becoming increasingly serious, and our government has vigorously promoted the substitution of degradable plastics. In 2021, my country’s degradable plastic market size will be approximately 18 billion yuan, and it is expected to reach more than 22 billion yuan by 2026. As one of the mainstream polyester degradable plastic products, PBSA’s market space is also growing.
Optimistic about the market development prospects, the number of companies entering the PBSA industry in my country is increasing. In 2011, Kingfa Technology’s PBSA project achieved industrial production; in 2019, Lanshan Tunhe PBSA project successfully discharged materials; in 2020, Sinopec Yizheng Chemical Fiber achieved industrial production of PBSA; Xinfu Technology also has the ability to produce PBSA industrially.
Industry analysts said that dibasic acid glycol polyester degradable plastics are the main product type of petroleum-based degradable plastics , PBSA is one of them. In order to achieve sustainable development, our government is vigorously promoting the replacement of non-degradable plastics with degradable plastics. Against this background, PBSA has a huge market space. At present, among my country’s PBSA production companies, Kingfa Technology and Yizheng Chemical Fiber are advanced companies in the resin industry. New entrants need to have certain competitive strength to compete with these companies.
