What are the application areas of p-Phthalic acid?

The p-Phthalic acid is mainly used in the production of polymer plastics and engineering plastics, synthetic dyes, polyester fibers, etc. In addition, it can also be used for PET and polyvinyl chloride plastics, and used as a raw material for synthetic resins and coatings.

So what are the application areas of p-Phthalic acid?

1.Polymer plastics

The p-Phthalic acid is mainly used in the production of polymer plastics and engineering plastics, such as a new generation of high-performance polystyrene, polymethacrylic acid and polyamide plastics. More than 99% of p-Phthalic acid can also be used to prepare various types of plastic molding products: polyethylene plastics, polypropylene plastics, polyvinyl chloride plastics, polymethyl methacrylate and polyamide plastics, which are used to manufacture related products such as electronics, machinery, automotive industry, food industry, medical and health industry, construction industry, and maintenance equipment.

2.Polyester fiber

The p-Phthalic acid can also be used to produce polyester fiber. Polyester fiber refers to fine fibers made from polyester and its mixture as raw materials. Polyester fiber is an important raw material for clothing fabrics, webbing, automotive interiors, furniture cushions, architectural decoration and other industries. Polyester fiber can be made from p-Phthalic acid, polyvinyl chloride and isoprene methyl acrylate through splicing, molding, extrusion or biaxial stretching.
