Common Applications of Para-Xylene in the Chemical Industry
PET Resin and Polyester Production
Over 97% of p-xylene (PX) is used to produce PTA and DMT, which are core raw materials for the production of PET resin and polyester fibers. The final products are widely used in packaging (e.g., plastic bottles), the textile industry, and film manufacturing, making this the primary use of para-xylene.
Chemical Intermediates
Para-xylen is a key raw material in chemical synthesis, providing the basic materials for the production of various chemical products.
Industrial Solvent
Whether as a component of mixed xylenes or as a standalone specialized solvent, p-xylene is widely used in industrial production processes. It is a key auxiliary material in the manufacture of coatings, adhesives, and printing inks, and can also be used as a specialized solvent in the rubber and leather industries.
Organic Intermediates
Para-xylen is an important raw material for the synthesis of special aromatic compounds.
Petroleum Industry
In the petroleum industry, p-xylene is formulated as a core component of paraffin solvents, primarily used for cleaning petroleum pipeline equipment.
