Para-aramid drives the development of para-phenylenediamine industry

Paraphenylenediamine, also known as Ursi D, is an organic compound with the chemical formula C6H8N2. It is one of the simplest aromatic diamines and a widely used intermediate.

At present, p-phenylenediamine is mainly used in the fields of dyes/pigments and rubber additives. p-phenylenediamine can be synthesized into azo disperse dyes, acid dyes, direct dyes, sulfur dyes and other dyes. P-phenylenediamine and its Rubber antioxidants whose main raw materials are derivatives have good effects.
             
In addition, p-phenylenediamine has gradually been applied in the fields of para-aramid fiber, new p-phenylenediamine rubber antioxidants, p-phenylenediamine synthetic resin and other fields, which has greatly expanded the application scope of p-phenylenediamine and driven the development of p-phenylenediamine. Growth in market demand.

Para-aramid is the most promising application field for p-phenylenediamine. With the breakthrough of China’s para-aramid industrialization technology, the construction of para-aramid equipment, a high-performance material encouraged by the state, has been significantly accelerated. Among them Taihe New Materials Company plans to increase its para-aramid fiber production capacity to 20,000 tons by 2024, which will greatly promote the rapid growth of market demand for para-phenylenediamine. According to the “P-phenylenediamine Industry In-depth Market Research and Investment Strategy Suggestions Report 2022-2026 released by the Industrial Research Center, It is expected that China’s demand for paraphenylenediamine will reach about 60,000 tons in 2025.

P-phenylenediamine is highly toxic, which limits its application. The production of p-phenylenediamine will produce a lot of pollution. The country has relatively strict environmental protection access standards for the production of such products. And as environmental protection policies become stricter, the production costs that p-phenylenediamine manufacturers need to pay are also increasing. In recent years, some companies that fail to meet environmental protection standards have gradually withdrawn from the market, and the market concentration of paraphenylenediamine has continued to increase. At present, China’s paraphenylenediamine market share is mainly concentrated in the hands of a few companies such as Zhejiang Longsheng Group Co., Ltd., Dingyuan County Shangshi New Materials Co., Ltd., and Anhui Gaosheng Chemical Co., Ltd.

Industry analysts said that China has not yet established a complete policy and standard system specifically for the p-phenylenediamine industry, resulting in my country’s The degree of standardization in the phenylenediamine industry is low, and product quality is uneven. my country’s paraphenylenediamine industry needs to establish a paraphenylenediamine policy and standard system that is suitable for my country’s industrial characteristics and in line with international standards as soon as possible, and improve standards and specifications for paraphenylenediamine products, methods, and pollutant emissions in the production process as soon as possible.
