What is Poly (butylene succinate-co-adipate)/PBSA

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 and caused huge harm to the ecological environment.

According to industry analysts, dibasic acid glycol polyester degradable plastics are the main product types of petroleum-based degradable plastics, and 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.

Polybutylene succinate-adipate (PBSA) has excellent physical properties and biodegradability.

It is generally made from fossil resources and can be degraded by microorganisms in the natural environment. The decomposition rate is higher than 90% in 180 days under composting conditions.

PBSA is currently one of the most enthusiastic categories of biodegradable plastics in terms of research and application.

PBSA is also a fully biodegradable thermoplastic aliphatic polyester with good flexibility, high-impact resistance and processability.

1.By blending PLA and PBSA, the two polymers can theoretically complement each other in terms of mechanical properties, resulting in a biodegradable polymer material with excellent comprehensive properties. Use PEG as a plasticizer to improve the flexibility of PLA films.

2.In order to make up for the shortcomings of a single starch material, thermoplastic starch TPS and biodegradable aliphatic copolyester PBSA are blended and modified to improve the physical and mechanical properties of starch-based degradable plastics such as tensile strength and tear resistance.

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 and caused huge 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.

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.

PBSA can be used in 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 is vigorously promoting the replacement of degradable plastics!
