AGY ? HS
Manufacturer page / TDSDescription
Zentron single-end roving; 360 tex; nominal yield 1400 yd/lb; end count 1; 9 µm filament; inside / outside draw; binder 561. Mechanical fields are left blank because the official product table provides relative S2-Glass performance rather than grade-specific absolute tensile values.
Comparative overview
Glass fiber — High-strength / high-modulus glass (S, R, T or equivalent)
Strengths: Higher tensile strength, strain capability, fatigue and impact tolerance than ordinary E-glass while remaining electrically insulating.
When to use: Select for rotor blades, pressure vessels, ballistic/impact panels, aircraft interiors and cost-effective radomes requiring more performance than E-glass.
Key tradeoffs: Higher density and lower specific stiffness than carbon, with a substantial price premium over E/E-CR glass.
Qualitative ratings (1–10 scale)
| Relative cost | 6/10 — Moderate–high — specialty S/R/T-type glass with higher raw-material and melting-control cost. |
|---|---|
| EM transparency | 8/10 — Very good — good dielectric behavior, though low-Dk glass/quartz are superior for the most demanding RF windows. |
| Temperature / fire resistance | 8/10 — Very high — non-combustible with improved strength retention and processing temperatures versus E-glass. |
| Impact / penetration resistance | 8/10 — Very high — high strength and strain give very good low-velocity impact, fatigue and damage tolerance. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically and thermally insulating. |
| Specific tensile strength | 4/10 — 4/10 | 1085.3 kN·m/kg | Class median |
| Atmospheric durability | 7/10 — Good — high-strength glass retains useful outdoor durability, but moisture-assisted crack growth can reduce filament strength under sustained stress. |
| Sustainability (CO₂e) | 9/10 — 1.70 kg CO₂e/kg fiber — Low emissions — data quality: Medium |
