Stockpiling Core Resources to Empower Market Growth

- Our Company Increases Inventory of Black Meta-Aramid 35s/2 Sewing Thread by 20 Tons

Recently, Suzhou Hengsian Protection Technology Co., Ltd. has completed the inventory expansion of black meta-aramid 35s/2 sewing thread, with the new stock increased by 20 tons. This provides core material support for the stable production of customers in downstream fields such as fire protection, metallurgy, aerospace and aviation, further consolidating the company's service advantages in the field of special sewing thread supply.

As the exclusive general distributor of Toray (Korea) Group's meta-aramid products in China, the company's inventory increase this time is based on accurate judgment of industry trends. According to industry reports, the global aramid market scale is expected to exceed 15 billion US dollars in 2025. Among them, the demand for meta-aramid in protective equipment, industrial filtration and other fields continues to rise. As a key connecting material for end products, the market annual growth rate of special sewing thread has reached 14.6%. Made from aramid 1313, black meta-aramid 35s/2 sewing thread has excellent high-temperature resistance, flame retardancy and corrosion resistance, and can withstand high-temperature environments of 200-500℃. It is the core sewing material for fire fighting suits, arc protective clothing, high-temperature filter bags and other products, which can effectively avoid protection failure caused by thread fusing under extreme working conditions.

This inventory expansion is an important implementation of the company's "demand-oriented + precise stockpiling" strategy. In recent years, with the industrial upgrading of new energy vehicles, high-end equipment manufacturing and other industries, downstream customers have significantly higher requirements for the procurement timeliness and batch stability of special sewing thread. The newly added 20 tons of inventory will be dynamically monitored through the digital inventory management system, ensuring that the order response time is shortened by more than 30%. At the same time, it can meet the customized needs of multiple batches and small quantities, reducing the production material preparation cost for customers.

The company's person in charge stated that this inventory adjustment is not only an active layout in response to market growth, but also a specific action to practice the concept of "assured supply of protective materials". In the future, relying on the synergy advantage of Jiangsu aramid industrial cluster, the company will continue to optimize the stock structure of special fiber products, simultaneously improve technical service capabilities, and provide more reliable protective material solutions for global customers.

Major Breakthrough in Domestic High-End Aramid! Independent Mass Production of 5000-Ton Grade High-Strength/High-Modulus PPTA Fiber Achieved

On October 17, 2025, the China National Textile and Apparel Council organized a scientific and technological achievement appraisal meeting in Yangzhou City, Jiangsu Province, for the "Key Technologies for Green Preparation of High-Strength/High-Modulus Para-Aramid" project, jointly completed by Sinochem High Performance Fiber Materials Co., Ltd. and Donghua University. The appraisal committee concluded that the project's achievements have reached internationally advanced levels. A brief introduction of the project's research findings is as follows:

Project Research Background

High-performance para-aramid (PPTA) is a critical strategic material for China, possessing both military and economic value. It is widely used in aerospace, military, ballistic protection, and various other fields, making it an important dual-use material. By 2025, the global market demand for PPTA is projected to reach 120,000 tons, with an annual growth rate exceeding 9%. China's military and high-end manufacturing sectors alone require nearly 10,000 tons of high-strength products annually. Since the industrialization of PPTA fiber in 1972, US-based DuPont and Japan's Teijin have held an absolute advantage in high-end manufacturing and downstream applications due to their technological accumulation. As of 2024, their respective production capacities account for 40% and 35% of the global total, with high-strength/high-modulus products occupying a significant market share. Although domestic Chinese enterprises have made considerable progress in PPTA manufacturing technology and industrial development with policy support, they still face challenges such as poor batch stability, small scale, weak capabilities in differentiated products and downstream application technologies, making it difficult to meet high-end demands. Therefore, the development of industrial-scale technology for high-end PPTA fibers is urgently needed.

To meet the needs of major national projects, achieve rapid development in China's high-performance fiber industry, and fill the gaps in domestic high-performance fiber technology, Sinochem High Performance Fiber Materials Co., Ltd. has established an annual production capacity of 5,000 tons of high-strength/high-modulus aramid fiber, utilizing proprietary production technology. This initiative aims to promote the high-quality, stable development of China's high-end PPTA fiber, differentiated products, and downstream product industries, thereby enhancing international competitiveness. The project has broken through the "bottleneck" of large-scale, stable production technology for high-strength/high-modulus PPTA fiber in China and achieved the localization of the key equipment industry chain.

Major Project Innovations

· Developed low-temperature solution polycondensation process control technology for high-capacity reactors, enabling the stable production of PPTA with high molecular weight and narrow distribution.
· Overcame the technology for rapid and efficient dissolution of high molecular weight para-aramid polymer, enhancing the uniformity of PPTA fiber in industrial production.
· Developed liquid crystal spinning and high-modulus, low-strength-loss heat treatment technology for high-modulus para-aramid, as well as fine-denier per filament liquid crystal spinning technology for high-strength para-aramid. The initial modulus of the high-modulus 1500D product reached 837 cN/dtex, and the breaking strength of the high-strength 1000D product reached 24 cN/dtex.
· Established a calcium chloride recycling technology for the polymerization process, where the recovered calcium chloride solution meets the requirements for the polymerization process.

Project Industrialization and Application Status

The project has successfully established a 5,000 ton/year high-strength/high-modulus PPTA fiber production line, which has entered the industrial operation phase. The integrated polymerization and spinning processes are fully automated and operating at designed capacity and efficiency. Product quality and stability are steadily improving, with performance meeting the demands of the high-end market. The company is currently supplying various specifications of high-strength and high-modulus fiber products to the market.

Sinochem High Performance Fiber Materials Co., Ltd. has built its own marketing network system and leverages Sinochem's international sales platform. It has established strong cooperative relationships with entities such as the PLA General Logistics Department, the PLA General Armaments Department, Jiangsu Hengtong, and Shenzhen Changfei, possessing a solid customer base. The products are stably supplied to numerous application fields including ballistic protection, automotive industry, industrial equipment, and aramid composites. They have received high market recognition and have successfully entered the supply chains of major leading enterprises.
