Shanshan Resources Group (Shanshan) continues to supply high‑quality PTA Purified Terephthalic Acid to the domestic and international polyester industry. With a minimum purity of 99% and CAS No. 100‑21‑0, the product is available as a white solid powder and is widely used in polyester fibres, bottle‑grade chips, films, and fine chemical modification applications.
Product Positioning and Industry Background
PTA is the key organic acid raw material for PET (polyethylene terephthalate) production, with approximately 90% of global PTA supply consumed in PET synthesis. In typical production processes, about 0.855 tonnes of PTA are required per tonne of PET produced. Established in 2010 as a first‑level subsidiary of Shanshan Holdings, Shanshan Resources Group has a registered capital of RMB 200 million, providing strong financial strength and resource integration capabilities to ensure stable supply of bulk commodities.
Product Quality and Standards
The PTA supplied by Shanshan is strictly controlled to a purity of 99.9% or higher, with all physical and chemical indicators meeting international mainstream standards. The company has obtained CQC management system certification and IQNet international certification (covering ISO 2011/2014, etc.). Each batch is accompanied by a COA report to ensure full quality traceability.

Typical Application Scenarios
Polyester fibre production (approx. 75% of domestic consumption): As the main raw material for synthetic fibres, PTA ensures excellent wrinkle resistance, shape retention, and uniform dyeing, and is widely used in apparel, home textiles, and industrial fabrics.
Bottle‑grade PET packaging: High‑purity PTA produces bottle preforms with excellent transparency and barrier properties, making it the preferred material for carbonated beverages, drinking water, and food packaging containers.
Film and tape manufacturing: Used in the production of BOPET (biaxially oriented polyester) films, suitable for high‑end industrial applications such as electrical insulation, packaging printing, and photosensitive materials.
Fine chemicals and modification: As a synthesis intermediate for high‑purity PTA plasticisers and other specialty chemicals, it significantly enhances the heat resistance and chemical stability of downstream plastic products.
Packaging and Logistics
Shanshan supports a variety of packaging options, including 20‑kg small bags, tonne bags, drums, and bulk sea‑freight shipping. All packaging is treated for moisture resistance to ensure material stability during long‑distance transport. Shipments can be arranged via container vessels or dry bulk carriers to accommodate different receiving preferences.
Pricing Mechanism
PTA pricing is flexible and competitive. Both fixed prices and floating prices (e.g., PX‑linked prices or daily average prices) are available and updated daily. For long‑term partners, Shanshan offers volume‑locked and price‑locked solutions to help mitigate operational risks arising from commodity price fluctuations.
