Purified terephthalic acid, as the core monomer of polyester synthesis, is characterized by high-purity carboxyl crystal structure, heat sensitivity and strong hygroscopic tendency.

In the field of chemical raw materials, the core value of high purity raw material terephthalic acid, which is different from conventional grade products, lies in the stability and reliability of its inherent quality.

The storage stability of PTA powder pure terephthalic acid is closely related to its molecular lattice structure and surface physical and chemical behavior.

The intrinsic quality of polyester staple fiber is jointly shaped by the regularity of the material structure and the fineness of the drawing process.
