Terephthalic acid(Cas 100-21-0) Usage

Description	Terephthalic acid is an organic compound with the chemical formula C₆H₄(CO₂H)₂. It exists as a white solid and is classified as a benzenedicarboxylic acid, with carboxy groups located at positions 1 and 4 on the benzene ring. It is one of the three possible isomers of benzenedicarboxylic acid, with the others being phthalic and isophthalic acids. Terephthalic acid is a conjugate acid of terephthalate(1-).
Precursor to PET	Terephthalic acid is primarily used as a key raw material in the production of polyethylene terephthalate (PET). PET is a widely used polyester resin employed in the manufacture of clothing fibers and plastic bottles. Several million tons of terephthalic acid are produced annually for this purpose.
Polyester Fibers	Terephthalic acid serves as a crucial component in the production of polyester fibers. These fibers, derived from PET, are utilized in various textile applications, including apparel, home furnishings, and industrial textiles.
Polyester Films	Polyester films based on terephthalic acid find applications in audio and video recording tapes, data storage tapes, photographic films, labels, and other sheet materials. These films offer excellent mechanical properties, optical clarity, and dimensional stability, making them suitable for diverse applications.
