Purified Terephthalic Acid (PTA) is one of the most important feedstocks in the global petrochemical and polyester value chain. As the primary raw material for polyester fiber, PET resin, engineering plastics, and advanced polyester films, PTA plays a vital role in numerous industries, including textiles, packaging, automotive, electronics, and consumer goods.
With decades of expertise in PTA manufacturing, Sinopec Yangzi Petrochemical is one of China's earliest large-scale PTA producers. Since entering commercial operation, the company has continuously advanced production technology, expanded capacity, and optimized manufacturing processes, establishing itself as one of the industry's most respected PTA suppliers.
The company's PTA production unit officially commenced operation in April 1990 with an initial annual capacity of 450,000 metric tons. At the time, it supplied more than 90% of China's domestic PTA market, successfully replacing imported products, breaking foreign technological monopolies, and filling a major gap in China's high-grade PTA production capabilities.
Through continuous technological innovation and facility upgrades, Yangzi Petrochemical has steadily improved production efficiency while developing complete PTA manufacturing technologies with independent intellectual property rights. Today, its PTA products have earned prestigious honors such as "China Famous Brand Product" and "National Customer Satisfaction Product," and are widely recognized throughout the industry for their outstanding quality and reliability.
Yangzi Petrochemical initially adopted patented PTA technology from Amoco Chemicals, establishing a solid foundation for high-purity production. Building upon this foundation, the company has continuously enhanced its manufacturing process through independent research and technological innovation.
Today, the company's PTA products achieve purity levels exceeding 99%, meeting China's premium quality standards. With extremely low impurity content, the material can be directly used in polyester esterification processes without secondary purification, making it ideal for manufacturing:
Its superior purity helps downstream manufacturers improve product consistency, processing efficiency, and final product performance.
As one of China's leading innovators in PTA technology, Yangzi Petrochemical has collaborated with Sinopec's research institutes to develop a complete PTA production process protected by independent intellectual property rights.
The company has obtained numerous national patents while establishing a mature industrial production system.
Continuous equipment optimization and energy-saving upgrades have significantly reduced production costs by:
These improvements provide significant cost competitiveness while ensuring stable large-scale production capacity, even in highly competitive global PTA markets.
More importantly, the successful commercialization of proprietary PTA technology has helped China's PTA industry reduce dependence on imported technologies and strengthened the country's independent petrochemical innovation capabilities.
Sinopec Yangzi Petrochemical operates a comprehensive quality management system covering every stage of production, including:
Multiple quality checkpoints are implemented throughout the manufacturing process to ensure consistent product performance.
Packaging accuracy, weighing systems, and storage procedures are routinely inspected and calibrated, minimizing product loss while guaranteeing shipment quality.
As a result, the company consistently achieves:
Its stable product quality has earned widespread recognition from customers across domestic and international markets.
Environmental sustainability has become a core component of Yangzi Petrochemical's PTA production strategy.
The company utilizes advanced VOCs (Volatile Organic Compounds) treatment technologies capable of efficiently processing both high- and low-concentration exhaust gases by converting pollutants into harmless carbon dioxide and water without generating secondary pollution.
Additionally, Yangzi Petrochemical has independently developed high-performance catalysts that successfully replace expensive imported alternatives while reducing operating costs by nearly two-thirds.
These technological innovations significantly improve environmental performance while lowering production costs, making the company a benchmark for sustainable PTA manufacturing within China's petrochemical industry.
Beyond manufacturing excellence, Sinopec Yangzi Petrochemical has played a leading role in establishing China's PTA quality standard system.
For many years, the global PTA industry lacked unified and authoritative quality and testing standards, creating challenges for international trade and industry standardization.
To address this issue, Yangzi Petrochemical collaborated with Sinopec Shanghai Research Institute of Petrochemical Technology and Yizheng Chemical Fibre to develop a comprehensive PTA standard system.
This achievement received the Third Prize of the 2024 China Quality Association Quality Technology Award.
The implementation of these standards has:
Benefiting from its high purity, excellent consistency, and low impurity levels, Yangzi Petrochemical's PTA products are widely used throughout the polyester industry.
Thanks to its reliable quality and stable supply capability, the company's PTA products have become preferred raw materials for numerous leading downstream manufacturers and are exported to customers worldwide.
As one of China's pioneers in PTA manufacturing, technology innovation, and industry standardization, Sinopec Yangzi Petrochemical has built a strong competitive advantage through decades of technological expertise, premium product quality, efficient manufacturing processes, and comprehensive quality management.
From replacing imported products and achieving technological independence to leading industry standards and supporting the global polyester value chain, Yangzi Petrochemical continues to provide world-class PTA solutions for the textile, packaging, engineering plastics, and advanced materials industries.
With its commitment to innovation, sustainability, and manufacturing excellence, Sinopec Yangzi Petrochemical remains a trusted global supplier of high-quality Purified Terephthalic Acid (PTA), contributing to the continued development of the international petrochemical and polyester industries.
