Core Insights - The article discusses the rapid development of the para-aramid fiber industry in China, highlighting significant advancements in technology, production capacity, and application innovation, positioning it as a key battleground for domestic substitution in the new materials sector [1][8]. Industry Overview - Para-aramid fiber, known as "poly(p-phenylene terephthalamide)" (PPTA), is synthesized from p-phenylenediamine and terephthaloyl chloride, exhibiting high strength, high modulus, heat resistance, and flame retardancy, ranking alongside carbon fiber and high-strength polyethylene as one of the world's top three high-performance fibers [2][8]. - The tensile strength of para-aramid fiber is six times that of steel wire, and its tensile modulus is two to three times that of steel and glass fibers, while its density is only one-fifth that of steel [2]. Production Capacity and Output - By 2024, China's para-aramid production capacity is projected to reach 31,000 tons per year, a year-on-year increase of 24% [1][8]. - Despite rapid growth in production, the utilization rate remains low, with a production of 15,000 tons in 2024, reflecting a 4.9% increase from the previous year, and a utilization rate of 48.4%, down 9.0 percentage points year-on-year [9][11]. Consumption Trends - The demand for para-aramid fiber is expected to remain strong, driven by economic development and national defense modernization, with consumption projected to grow from 13,000 tons in 2021 to 18,000 tons in 2024, achieving a self-sufficiency rate of approximately 83% [11][17]. - In 2024, the consumption structure shows that the optical fiber reinforcement sector accounts for 40.4%, followed by safety protection at 24.9% [13]. Industry Structure - The para-aramid industry has high technical barriers, historically dominated by a few multinational companies such as DuPont and Teijin, leading to significant reliance on imports in China [12][18]. - As of 2024, Taihe New Materials holds a production capacity of 15,500 tons, representing 50% of the national total, with other companies like Sinochem and Zhongfang Special Fiber also having substantial production capabilities [12][18]. Future Development Trends - The consumption of para-aramid fiber in China is expected to continue growing, potentially reaching 25,000 tons by 2030, with optical fiber reinforcement and safety protection products leading the growth [17]. - The industry is anticipated to undergo continuous expansion, with a focus on technological breakthroughs and cost optimization as core competitive factors, necessitating domestic companies to accelerate their transition to high-end products [18].
