Even among functional chemical products that have marked characteristics, purified isophthalic acid (PIA), purified telephthalic acid (PTA) and phthalic acid anhydride are derived from meta-xylene (MX), para-xylene (PX) and ortho-xylene (OX), respectively. These xylene isomer derivatives, including plasticizers, meta-xylenediamine and MX-nylon, are used as raw materials and modifiers for fibers, synthetic resins and paints, and are indispensable in industry and daily life. Furthermore, aromatic aldehydes, which are used in cosmetics and as resin additives, meet current consumer and industry needs.
Used as an oxidation barrier for plastic bottles and clear wrapping film, special function resins, paint curing agents, perfumes, and cosmetics.
Plasticizers, various polymerization initiators, and others, which are used for polyvinyl chloride blends.
Purified Isophthalic Acid, Pure Terephthalic Acid, and others are used to make PET bottles, and Phthalic Acid Anhydride is used to make plasticizers.
