According to the Biodegradable Materials Research Institute, due to the rising price of PBAT raw materials, Hengli announced that it will increase its PBAT products by 1,000 yuan / ton from March 2, which will be implemented immediately

At present, it seems that PBS can only be mass-produced in Tunhe, Lanshan, Xinjiang.

On February 24, Meirui New Materials (300848.

On February 24, Meirui New Materials (300848.
SZ) stated that the company has fully mastered the production technology of PBS products and is currently in the early stage of market development and verification
.
In addition, Meirui New Materials and Henan Energy also built a new 100,000-ton PBS project in Hebi
.

On February 25, Xuelang Biology (830821.
OC) stated that its PBS project, which invested 58 million yuan, has been completed and entered the trial production stage
.
In order to achieve industrial support, 38 million yuan will be invested to build an upstream raw material project - 10,000 tons of succinic acid, with a construction period of 11 months
.
Anhui Xuelang Bio has a 120,000-ton PBS project, which has a deep relationship with Fengyuan!

In fact, Xuelang Bio has been planning a succinic acid project as early as 2019.
At that time, due to environmental approval and funding reasons, it has not invested in construction.
As of the mid-year report in 2021, a total of 530,000 yuan has been invested in the project
.
Xuelang Biology believes that after the completion of the succinic acid project, a production system of independent supply of the company's main products and raw materials can be realized, and benefits can be generated after the project is put into operation.
In the long run, it will have a greater impact on the company's profitability and comprehensive competitiveness.

According to the future PBS production capacity planning of each company, there are 850,000 tons: Hengli has 300,000 tons, Shandong Linqu Qili Jinrui 100,000 tons, Shandong Xuke New Materials 100,000 tons, Meirui New Materials 100,000 tons, Inner Mongolia Jiutai 60,000 tons tons, Henan Energy Kaixiang 60,000 tons, Hebei Bohang New Materials 60,000 tons, Lanshan Tunhe 40,000 tons, Yangzhou Puliter 30,000 tons.

Hubei Yihua, Wuheng Chemical and Henan Nanle County Hong‍ It may be involved in the planning of industry biology, and there are also rumors that Mogao shares have switched to PBS
.

So many companies plan to enter the ranks of PBS because PBS pure resin has excellent mechanical properties and processing properties, high crystallinity, heat distortion temperature and product service temperature can reach 100 ℃
.
From this point of view, it far exceeds PLA with a heat distortion temperature of only 60-70 °C.
Some PLA straw formulations need to add PBS to enhance temperature resistance
.
However, the production raw materials of PBS are 1,4-butanediol and succinic acid.
The unit price of the former is 28,000 yuan, and the unit price of the latter is 19,000 yuan.
Both are expensive goods, and the yield of PBS production is not high.
Production costs are high
.

For a long time, the PBS resin of Thailand PTT-MCC company has monopolized the domestic high-end market, and its unit price has reached 50,000 yuan/ton, while the domestic PBS pure resin is about 40,000 yuan/ton
.
The reason is that some domestic PBS pure resins have not yet passed the food safety test, and succinic acid and tetrahydrofuran are easily precipitated in 95% ethanol solution exceeding the standard.
Domestic PBS needs to be modified by materials before it can be used in tableware, such as Straws, lunch boxes
.

In the future, as Chinese enterprises overcome the problems of PBS product yield and precipitation, PBS materials will be more widely used
.
Liang Haitian, a PBAT/PBS technical expert, will answer the above questions at the Guangzhou Bio-based and Degradable Materials Forum held on April 13-15
