Paraxylene (PX) Uses
Production of Purified Terephthalic Acid (PTA)
Paraxylene (PX) serves primarily as the essential feedstock for Purified Terephthalic Acid (PTA) manufacturing. PTA is a crucial material used in producing Polyethylene Terephthalate (PET) - the base for polyester fibers, plastic packaging, and film products. It is widely used in the textile, packaging, and beverage industries.
Intermediate for Other Chemicals
In addition to PTA production, Paraxylene is an important chemical intermediate for synthesizing benzoic acid and p-tolualdehyde. These compounds play vital roles in the pharmaceutical, agricultural, and coating sectors, where they are used in making preservatives, pesticides, dyes, and specialty chemicals.
Paraxylene (PX) Standard Package:25kg /drum, 180kg / drum or 880kg / IBC Tank
