合成纤维原料系列
Terephthalic Acid (PTA, CAS 100-21-0) is a premium, high-purity white crystalline powder or needle-like solid. It is insoluble in water, ether, and chloroform, slightly soluble in ethanol, and readily soluble in alkaline media or Dimethyl Sulfoxide (DMSO). As a highly consequential aromatic dicarboxylic acid derivative within the global petrochemical matrix, PTA serves as the irreplaceable bedrock for polymer processing. Chemically reacted via polycondensation with Mono Ethylene Glycol (MEG), PTA acts as the primary precursor to synthesize Polyethylene Terephthalate (PET). Its downstream branches deeply empower texturized polyester filaments, technical heavy-duty industrial fibers, bottle-grade polymer chips, engineering thermoplastics, and high-performance unsaturated polyester resins (UPR), imparting superior thermal endurance, mechanical tensile strength, and elite chemical stability.

Core Applications
Polyester Fibers & Modern Apparel: Over 90% of global PTA supply is directed into synthesizing PET matrixes, subsequently converted into commercial polyester staple fibers and continuous filaments for clothing texturing, home upholstery, and high-tension safety nets.
Premium Bottle-Grade PET Chips: Deployed to manufacture highly clear, barrier-efficient PET flakes widely integrated across carbonated soft drink containers, mineral water bottles, thermoformed food packaging, and specialized optical films.
Engineered Plastics & Coatings: Essential co-monomer for processing Polybutylene Terephthalate (PBT) technical thermoplastics tailored for automotive housings and electrical sockets, and functions as a structural component in formulating anti-corrosive unsaturated polyester resins (UPR).
Advanced Eco-Friendly Plasticizers: Chemically processed with 2-ethylhexanol to yield Dioctyl Terephthalate (DOTP)—a premium, non-phthalate eco-friendly primary plasticizer effectively upgrading vinyl compounding.
Packaging & Storage
Packing: Customarily supplied in seaworthy 1100 KGS or 1000 KGS heavy-duty jumbo bags (PP woven bags with moisture-proof PE liners). Small trial orders support 25 KGS packages.
Storage: Store inside a completely dry, cool, and perfectly ventilated dedicated chemical warehouse away from extreme heat, open sparks, or ignition hazards. Meticulously isolate from powerful oxidizers. Protect from ambient humidity or rain during international ocean container transport.
