Purified Terephthalic Acid (PTA) Industrial Grade is the foundational bulk monomer of global polyester chemical industry, and Linkwin establishes strict raw material incoming inspection, intermediate process control and finished product full-index testing system for PTA product, ensuring low 4-carboxybenzaldehyde (4-CBA), low p-toluic acid and high purity to meet high-speed continuous polycondensation production requirements of downstream PET manufacturers. Our PTA adopts advanced oxidation, hydrogenation refining, centrifugal drying and screening process, with precisely controlled particle size distribution, good fluidity and uniform reaction activity; low impurity content can effectively reduce side reactions during polymerization, improve intrinsic viscosity stability of finished PET products, lower filament breakage rate during fiber spinning and enhance transparency performance of polyester film and bottle grade resin. The finished PTA is white fine crystalline powder with good thermal stability, easy mixing and esterification reaction with ethylene glycol to generate polyethylene terephthalate (PET) polymer.

In industrial downstream application field, PTA and ethylene glycol polycondensation produce three major mainstream polyester products: polyester textile fiber including staple fiber and filament used for garment fabric, home textile and industrial textile manufacturing; bottle-grade PET resin applied for beverage bottles, edible oil packaging bottles, cosmetic packaging containers and food packaging plastic containers; BOPET polyester film widely used for packaging film, electrical insulation film, solar backsheet film, optical film and printing composite film production. In addition, PTA is also raw material for polyester engineering plastic, polyurethane coating and polyester adhesive synthesis, covering textile, packaging, new energy, electronic appliance and many other industrial sectors. Many overseas polyester manufacturers suffer unstable viscosity, spinning end breakage and poor film transparency problems caused by high 4-CBA and inconsistent particle size from inferior PTA suppliers; our strict hydrogenation purification technology and batch inspection mechanism fundamentally solve these production obstacles, stabilizing your finished product yield and quality competitiveness.

Standard packaging adopts 1000kg ton jumbo bag, customized bulk tanker shipment is available for super-large long-term orders to minimize unit logistics cost. We maintain large monthly output and sufficient inventory to shorten order delivery cycle and eliminate raw material supply interruption risks for your continuous polymerization production line. Complete export certification documents including batch COA, MSDS, product analysis report can be rapidly issued to accelerate customs clearance procedures for petrochemical import regulations globally. Our professional sales team calculates targeted FOB and CIF quotations based on order volume and destination port, provides technical index matching consultation for different PET grade production demands, and supports small sample testing before bulk order. Cooperating with Linkwin for PTA procurement optimizes your polyester raw material cost structure, stabilizes finished product quality consistency and builds long-term competitive edge in global polyester supply chain market.
