Description

Inherently heat- and flame-resistant meta-aramid fiber that will not melt, drip or support combustion.. Product form: Fiber raw material for yarn spinning and fabric weaving. Official source: EX-META-NOMEX

Comparative overview

Aramid fiber — Meta-aramid thermal/protective fiber

Strengths: Inherent flame resistance, electrical insulation and thermal stability without melting or dripping.

When to use: Select for protective clothing, fire barriers, filtration, electrical insulation and aerospace interiors rather than maximum tensile reinforcement.

Key tradeoffs: Lower tensile structural performance than para-aramid; moisture uptake and compression limitations must be considered.

Qualitative ratings (1–10 scale)

Relative cost	6/10 — Moderate–high — specialty protective-textile fiber, but produced at larger scale than PBO or ceramic fibers.
EM transparency	9/10 — Excellent — electrically insulating and generally RF transparent.
Temperature / fire resistance	8/10 — Very high — excellent heat/flame resistance for an organic fiber and retains protection under repeated thermal exposure.
Impact / penetration resistance	4/10 — Moderate — good textile toughness, but much lower tenacity and ballistic efficiency than para-aramid.
Electrical / thermal conductivity	1/10 — Very low — electrically insulating and a poor heat conductor.
Specific tensile strength	2/10 — 2/10 \| 507.2 kN·m/kg \| Family estimate
Atmospheric durability	6/10 — Good — strong heat and chemical resistance for an organic fiber, although prolonged UV exposure can still cause discoloration and property loss.
Sustainability (CO₂e)	6/10 — 9.50 kg CO₂e/kg fiber — Medium emissions — data quality: Low
