Due to the use of degradable plastics in soil, compost, ocean, and freshwater (rivers, rivers, lakes)
There will be different degradation behaviors in the environment, depending on different environmental conditions
Degradable plastics are divided into:
⚫ Soil degradable plastics;
⚫ Compostable and degradable plastics (including traditional composting and courtyard composting);
⚫ Marine environment degradable plastics;
⚫ Freshwater environment degradable plastics;
⚫ Anaerobic digestion of sludge to degrade plastics;
⚫ High solid anaerobic digestion and degradation of plastics.


PBAT belongs to thermoplastic biodegradable plastics
The full name of PBAT is polyadipic acid/butylene terephthalate, also known as Poly in English
The abbreviation for butyleneadipate co terephthalate is succinic acid succinate
A copolymer of alcohol ester and butylene terephthalate, which combines the characteristics of PBA and PBT,
It has good ductility and elongation at break, as well as good heat resistance and impact resistance
Can; In addition, it also has excellent biodegradability, which is one of the research focuses on biodegradable plastics
One of the most active and widely used biodegradable materials in the market.
Characteristics: PBAT is a semi crystalline polymer, usually with a crystallization temperature of 110 ℃
Nearby, with a melting point of around 130 ℃ and a density between 1.18g/ml and 1.3g/ml.
The crystallinity of PBAT is approximately 30%, and the Shore hardness is above 85.
PBAT has a relatively large market share and is currently the main source of biodegradable materials replacing traditional plastics
We need products mainly because PBAT materials have good mechanical properties and are relatively good compared to other materials
Degradable materials have lower prices and costs, and have lower substitution resistance.


PBAT is formed by direct esterification and condensation with BDO/AA/PTA as the main reaction raw material under the action of a catalyst. PTA, AA, and BDO are added to the slurry configuration at a certain molar ratio and mixed
After mixing and refining, it is transported to the esterification reactor 1. At a certain temperature and pressure, it undergoes two stages of esterification reaction to generate oligomers. At the same time, the water generated by the esterification reaction, the by-product THF, and the entrained BDO enter the separation process
Tower separation, esterification 2 oligomer enters polycondensation 1 for polycondensation reaction, undergoes a three-stage polycondensation reaction to generate polyadipic acid/butylene terephthalate (PBAT) melt, which is then subjected to underwater granulation, drying and dehydration
The main product PBAT obtained from water is currently in strong demand in the global PBAT market. Due to the high price of PBAT, China has good raw material production conditions. PBAT products are mainly used for export, industry
High concentration, large potential market, and good industrialization prospects.

Ningbo Changhong Polymer Scientific and Technical Co., Ltd. invests in the construction of "600,000 tons/year PBAT/PBS/ PBT flexible production project in a fully biodegradable thermoplastic industrial zone" in two phases, with 300,000 tons/year in each phase and a total construction period of 5 years. In the first phase, a production line of 100,000 tonnes/year will be built first, which can flexibly produce different products such as PBAT, PBS and PBT according to the market demand, and also has the ability to expand and modify the chain to produce other different grades of products. The first phase of the project is expected to have an annual output value of RMB 2 billion and an annual tax payment of RMB 120 million.
