Teijin Aramid ? High Tenacity
Manufacturer page / TDSDescription
Dope-dyed black grade with improved UV resistance. Copolymer aramid with high thermal and chemical stability.
Comparative overview
Aramid fiber — Ballistic / high-tenacity para-aramid
Strengths: Excellent specific tensile strength, toughness and energy absorption; fibers spread and dissipate impact energy while remaining dielectric and flame resistant.
When to use: Select for soft/hard armor, helmets, fragment protection, ropes, impact skins and hybrid laminates where toughness matters more than compression stiffness.
Key tradeoffs: Low compressive strength, moisture uptake, UV sensitivity and difficult machining/bonding; carbon is better for pure stiffness.
Qualitative ratings (1–10 scale)
| Relative cost | 8/10 — High — ballistic-grade para-aramid requires controlled spinning, yarn and finish quality. |
|---|---|
| EM transparency | 9/10 — Excellent — dielectric organic fiber suitable for RF-transparent structures when the matrix and moisture state are controlled. |
| Temperature / fire resistance | 6/10 — Good — flame resistant and non-melting, but organic decomposition limits sustained hot-section use. |
| Impact / penetration resistance | 10/10 — Top-tier — proven high-velocity penetration resistance and energy dissipation in soft and hard armor. Stored TDS elongation: 4.3%. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically insulating with very low thermal transport. |
| Specific tensile strength | 8/10 — 8/10 | 2374.1 kN·m/kg | Product TDS |
| Atmospheric durability | 6/10 — Good — Technora has low moisture uptake and improved chemical/environmental durability relative to conventional para-aramids, but prolonged UV exposure should still be limited. |
| Sustainability (CO₂e) | 6/10 — 8.70 kg CO₂e/kg fiber — Medium emissions — data quality: Medium |
