Japan Polyacrylonitrile (OPAN) Fiber Industry Report 2026: Growth Outlook to Reach 259 Million USD
Oxidized polyacrylonitrile (OPAN) fibers refer to fibers that are thermally stabilized in an oxidizing atmosphere at approximately 200 to 300°C, converting the molecular chains into a heat-resistant conjugated ladder structure. The global market for oxidized polyacrylonitrile (OPAN) fibers is expected to expand from approximately 242 million USD in 2025 to about 259 million USD in 2026, growing at a CAGR of 7.2% from 2026 to 2032, and reaching around 394 million USD by 2032. The global production volume in 2025 is estimated to be about 20,500 tons, with a weighted average price of approximately 11,800 USD/ton and a manufacturing gross profit margin of around 23-32%. OPAN fibers are difficult to melt or drip, possess a high Limiting Oxygen Index (LOI), low thermal conductivity, dimensional stability, chemical resistance, and electrical insulation properties.

Applications/Examples of results
Thermal safety demand for oxidized polyacrylonitrile (OPAN) fibers Oxidized polyacrylonitrile (OPAN) fibers are expanding their applications from traditional flame-retardant blankets, welding fabrics, and high-temperature sealing materials to electric vehicles, energy storage batteries, aircraft brakes, and advanced carbon materials. In particular, OPAN needle felt and OPAN-aerogel composites are promising growth areas as thermal barrier materials that delay thermal runaway propagation in battery packs. Since OPAN possesses inherent flame retardancy without relying on brominated or halogenated flame retardants, it also has high application value in flame barrier layers, insulation materials, and protective equipment.
