Description:
Paraxylene (PX) is a colorless, aromatic hydrocarbon derived from crude oil refining and naphtha reforming. It is primarily used as a key raw material in the production of purified terephthalic acid (PTA) and dimethyl terephthalate (DMT), which are essential components in manufacturing polyester fibers, resins, and films. Due to its high purity and efficiency in polymer production, paraxylene plays a crucial role in the textile, packaging, and plastic industries.
PX is highly valued for its ability to enhance the durability, flexibility, and strength of polyester-based products. It undergoes advanced refining and purification processes to meet the stringent quality requirements of the petrochemical industry.
