A few days ago, the public participation in the environmental impact assessment of the 60,000 tons/year fully biodegradable plastic PBAT project of Huizhou Broke Environmental Protection New Materials Co.
, Ltd.
was announced for the second time
.
Huizhou Brocade New Materials is a subsidiary jointly invested by Yuxin and Huizhou Brocade Huifu Equity Investment Partnership in September 2020
.
On August 20, 2020, Yuxin Co.
, Ltd.
and Huizhou New Materials Industrial Park Planning and Construction Headquarters signed the "Strategic Cooperation Framework Agreement" on the company's investment and construction of light hydrocarbon comprehensive utilization projects in Huizhou New Materials Industrial Park.
The projects include pilot projects and main projects, with a total investment of approximately RMB 15.
9 billion
.
Among them, the pilot project is a 60,000-ton/year PBAT project with an investment of about RMB 500 million

Process principle
Process principle
This project adopts the direct esterification method (esterification-polymerization process) for resin production
.
The reaction principle is that terephthalic acid (referred to as "PTA", the same below), adipic acid (referred to as "AA", the same below) are reacted with 1,4-butanediol (referred to as "AA", the same below) in the high temperature environment of the esterification kettle, respectively.
"BDO", the same below) undergoes esterification to produce butylene terephthalate, 1,4-butyl adipic acid; butyl terephthalate and 1,4-butyl adipic acid Finally, polyadipate/terephthalate (abbreviated as "PBAT", the same below) is formed by polycondensation
.
In the production process of PBAT, the conversion rate of esterification and polycondensation is about 99%
.
