Purified terephthalic acid (PTA)
UsageThis product is the main raw material for producing polyester. It can be directly esterified and condensed with ethylene glycol to obtain polyester, and can also be made into engineering polyester plastics. It can also be used as a raw material for plasticizers and dye intermediates.
Packaging, storage and transportation
Bagged products are packaged in bags lined with plastic film, with a net weight of 1000 ± 2kg per bag. The packaging bag should be printed with the manufacturer's name, address, trademark, product name, grade, batch number, net weight, and standard code. Stainless steel tank cars can also be used for shipping. Before loading, the tank car should be checked for cleanliness and dryness. After loading, the feed inlet should be sealed and lead sealed. During product transportation, it is necessary to prevent fire, moisture, and static electricity. Bagged products should be handled with care to prevent packaging damage; During tank truck loading and unloading operations, attention should be paid to controlling the loading and unloading speed to prevent the generation of static electricity. It should be stored in a cool, ventilated, and dry warehouse, away from flames and heat sources. It should be stored separately from oxidants and acid-base substances, and should be protected from sunlight and rain. It should not be stored outdoors
SWOT analysis of the development of purified terephthalic acid industry
The PTA price difference is significantly affected by the cost side, especially the PX price; In 2022, due to the impact of high refined oil prices, PX prices remained strong in the short term, forcing a significant reduction in PTA processing fees. From the perspective of industry chain profits, in the past five years, the profits of the PX-PTA polyester industry chain have undergone significant changes, which can be mainly divided into three stages: from 2017 to 2019, industry profits were mainly concentrated in PX upstream of the industry chain. From 2019 to 2020, domestic integrated refining and chemical projects entered a centralized production period, resulting in a significant decline in overall profitability. In 2021, profits flowed back from the midstream to the upstream and downstream, with PTA beginning to experience losses.
For PTA, although the production capacity investment will significantly exceed the demand growth rate in the coming years, under the continuous low processing costs, if backward production capacity exits beyond expectations, it will also promote the repair of price differences. In addition, unlike the upstream PX, PTA's capacity expansion is basically dominated by the head private enterprises, and will dominate the future capacity expansion. The industry concentration is expected to further improve, the downstream Bargaining power is stronger, and there is some support for the price difference trend.
