Supplier companies

4 companies produce nomex meta-aramid fiber.

Arclin (formerly DuPont Aramids)

HQ US35% share

Private-equity-backed company (TJC L.P.) that acquired DuPont's entire Aramids business — Kevlar (para-aramid) AND Nomex (meta-aramid) — for $1.8B on April 1, 2026. Nomex is the world's dominant meta-aramid fiber brand, used in firefighter turnout gear, military flight suits, electrical insulation, race car driver suits, and industrial thermal protection. Five manufacturing sites: Spruance (Richmond VA — ~975 employees, ISCC PLUS certified April 22, 2026), Monroe (North Carolina), LaPlace (Louisiana), Maydown (Derry, Northern Ireland — serves aerospace/EV/defense), Asturias (Spain — ISCC certified 2025). DuPont retained a 16-17.5% equity stake in Arclin plus a $300M promissory note from the sale. Arclin's President Mark Glaspey stated "operational continuity from day one" as the top priority. Nomex holds ~55% of global meta-aramid revenue market share — the PE ownership transition is the largest structural change in firefighter protective fiber supply in decades.

MSA Safety(MSA)

HQ US30% share

Leading global manufacturer of safety equipment including SCBA (G1 platform), turnout gear (Globe brand acquired July 2017 for $215M), gas detection, and thermal imaging. Combining dominant SCBA and turnout gear positions makes MSA the largest US supplier of structural firefighter life-safety equipment.

Yantai Tayho Advanced Materials Co., Ltd.

HQ CN20% share

Shenzhen Stock Exchange-listed (SZ: 002254) Chinese specialty fiber company; subsidiary of Taihe New Material Group (Yantai, Shandong). Produces Tametar meta-aramid fiber (17,000-20,000 MT/year capacity; >80% of Chinese domestic meta-aramid supply) alongside Taparan para-aramid. Two production locations: Yantai, Shandong (HQ); Pingdingshan, Henan (primary production). ~29.8% of global meta-aramid market capacity (but mostly Chinese domestic market). Key customer: Chinese military and security forces — Tametar aramid is used in "all newly designed public security police and armed police Special Forces Service uniforms" per Chinese government procurement. No confirmed Western NFPA 1971-certified turnout gear customers found in public sources. Chinese meta-aramid capacity expansion (industry-wide ~26,000-38,000 t/yr by 2025) created significant downward price pressure on Western meta-aramid producers, contributing to DuPont's decision to divest its Aramids business.

Teijin Aramid BV

HQ NL15% share

Dutch subsidiary of Teijin Ltd. (Japan; TSE: 3401); the world's second-largest meta-aramid producer (~20% global revenue share) under the Teijinconex brand. Meta-aramid production is in Japan (Iwakuni, Yamaguchi Prefecture — Teijinconex classic) and Thailand (Ayutthaya — Teijinconex neo, dyeable variant, 2,200 t/yr). The Netherlands facilities (Emmen, Delfzijl, Arnhem) produce para-aramid Twaron — NOT meta-aramid. Key distinction: when the Netherlands is listed as a meta-aramid producer, the corporate HQ is Dutch but actual meta-aramid fibers are made in Japan and Thailand. Arnhem pulp facility closing 2025. Teijinconex serves firefighter PPE, electrical insulation, and protective clothing globally. Teijinconex neo (Thailand) is dyeable to customer colors without additional chemical treatment, addressing a key limitation of Nomex.
