These components undergo polymerization to form PET (Polyethylene Terephthalate), which is then melt-spun into fibers. But not all polyesters are created equal. At Shanshan, we’ve optimized our sourcing to ensure high purity and consistency—because the quality of the Polyester Raw input defines the performance of the final product.

Pta powder pure terephthalic acid is a solid organic compound purified from terephthalic acid. Its chemical structure consists of a benzene ring and symmetrical carboxyl groups.

PET bottle chip is recycled polyester bottle material after recycling, sorting, crushing and cleaning. Its core feature is that it retains the molecular chain structure of virgin polyester and has the property of recycling.

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