Product Description
Phthalic Acid, also called Benzenedicarboxylic Acid with formula C6H4(COOH)2, is the name of any of three isomers.TPA has been used mainly as a raw material of polyester fiber but lately it has been exploited for various uses such as non-fiber field, PET-bottle, PET-film and engineering plastics and as poultry feed additives. Phthalic acid derivatives are also widely used to make dyes, medicine, and synthetic perfumes, pesticides, and other chemical compounds.
