CAS 106-42-3 Para-xylene (PX) is a colorless, highly flammable aromatic hydrocarbon. As a key petrochemical product refined from crude oil and reformate gasoline, it holds unique industrial value. One of three xylene isomers, its distinctive symmetry and chemical structure enable large-scale polymer synthesis.
p-Xylene plays a critical upstream role in the production of everyday materials such as polyester fibers, PET bottles, and packaging films.
Industrial Applications of Para-xylene
Polyester
Paraxylene (PX) serves as a foundational raw material for manufacturing purified terephthalic acid (PTA), which in turn acts as the core feedstock for polyester production. Thanks to their durability, wrinkle resistance, and cost efficiency, polyester fibers made from paraxylene are ubiquitous in clothing, home textiles, and industrial applications.
Textiles
Polyester fiber produced from para-xylene serves as a primary raw material for the textile industry. These fibers are spun into yarns and woven into fabrics for apparel, upholstery, and technical textiles.
Packaging Materials
Polyethylene terephthalate (PET), which is derived from paraxylene-based chemical intermediates, is one of the most widely used packaging materials today, available in both rigid and flexible forms. It is the material of choice for packaging beverages, food, pharmaceuticals, and household cleaning products due to its high strength, rigidity, transparency, and excellent resistance to moisture, oxygen, and carbon dioxide.
Plastic Film
P-Xylene (PX) plays a critical role in the production of plastic films, most notably polyethylene terephthalate (PET) films. These films are used in food wrapping, magnetic tapes, electrical insulation, and capacitor manufacturing.
Solvents
While para-xylene itself is not a major commercial solvent, its chemical relatives (other xylenes) are commonly used as solvents in paints, adhesives, inks, and cleaning agents. P-Xylene (PX) can also be blended into industrial solvent mixtures to help dissolve resins and dyes.
As a reliable p-Xylene manufacturer and supplier, we provide CAS 106-42-3 with strict quality control, stable large-volume supply, and comprehensive export documentation for international buyers.
