Toray Expands Meta-Aramid Fiber Production to Support AI, Power and Defense Demand

Updated on June 23, 2026 • 3 min read

Toray Advanced Materials has completed the expansion of its second meta-aramid fiber production line at its Gumi manufacturing complex, increasing total annual production capacity to 5,400 metric tons.

The investment reflects growing global demand for heat-resistant and electrically insulating materials used in power infrastructure, data centers, defense systems and next-generation mobility applications.

New Production Line Adds 3,000 Tons Capacity

The company announced that it recently held a completion ceremony for the new production line at its Gumi Plant No. 1 in North Gyeongsang Province.

The newly commissioned facility adds:

• 3,000 metric tons of annual production capacity
• Expanded supply capability for advanced industrial markets
• Greater support for domestic and international customers

Combined with its existing production line, Toray Advanced Materials now has a total annual meta-aramid fiber production capacity of 5,400 metric tons.

Approximately 120 government officials, industry representatives and company executives attended the inauguration ceremony.

Growing Demand for High-Performance Aramid Materials

Meta-aramid fiber is a high-performance synthetic material recognized for its:

• Heat resistance
• Flame-retardant properties
• Electrical insulation performance
• Long-term durability in harsh environments

The material can maintain its physical properties at temperatures exceeding 200°C, making it suitable for demanding industrial applications.

Key end-use sectors include:

• Power transmission and distribution infrastructure
• Electric mobility systems
• Defense equipment
• Industrial safety products
• Data center electrical systems

AI and Data Centers Drive New Opportunities

The expansion comes as rapid growth in artificial intelligence infrastructure and hyperscale data centers increases demand for reliable power networks and thermal management solutions.

As electricity consumption rises, utilities and equipment manufacturers are seeking advanced insulating materials capable of improving system reliability while operating under elevated temperatures.

Meta-aramid fibers are increasingly being used in electrical insulation components where heat resistance and long-term performance are critical.

Supporting Korea’s Advanced Manufacturing Sector

According to company leadership, the investment is intended to strengthen support for emerging high-tech industries while enhancing South Korea’s advanced materials supply chain.

Kim Young-seop, President of Toray Advanced Materials, described the project as a strategic investment aligned with the growth of future industries and the company’s long-term materials innovation strategy.
