The first in the country!

Recently, Guangdong Qingda Zhixing Biotechnology Co.
, Ltd.
and Shanxi Changqing Biotechnology Co.
, Ltd.
jointly built a sugar-based 1,3-propanediol (PDO) production unit with an annual output of 20,000 tons
.

The project is located in Changzhi City, Shanxi Province.
After the first phase is put into operation, it will form a bio-based 1,3-propanediol production capacity of 20,000 tons per year, providing a stable source of PDO for polyester, polyurethane, cosmetics, degradable plastics and other industries
.

1,3-Propanediol (PDO)

1,3-Propanediol is an important chemical raw material, widely used in polyester, polyurethane, cosmetics, degradable plastics, pharmaceutical intermediates, inks, printing and dyeing, lubricants and other fields
.
The main use of PDO is to polymerize with terephthalic acid (PTA) to produce polytrimethylene terephthalate ("PTT")
.

PTT is a new type of high-performance bio-based polyester fiber: in terms of physical properties, it has the stability of PET, the softness of nylon, the bulkiness of acrylic, the stain resistance of polyester, and the elastic recovery ability close to spandex, and has excellent Shape retention feature, also known as "memory fiber"; chemically, PTT is UV-resistant, chloride-resistant, and suitable for low-temperature dyeing
.
PTT has many excellent properties at the same time, and was named "King of Polyester" as early as the last century
