Comparative overview
Glass fiber — E-CR corrosion-resistant glass
Strengths: Retains the affordability and dielectric character of E-glass with improved acid/corrosion durability and typically boron-free chemistry.
When to use: Select for pipes, tanks, pultruded profiles, wind and chemical-service structures exposed to moisture or corrosive media.
Key tradeoffs: Heavier and less stiff per unit mass than carbon; not as strong as S/R-glass and chemical resistance still depends on matrix and environment.
Qualitative ratings (1–10 scale)
| Relative cost | 2/10 — Low — commodity-like glass with corrosion-resistant chemistry and a small price premium over E-glass. |
|---|---|
| EM transparency | 8/10 — Very good — retains E-glass dielectric and insulating character. |
| Temperature / fire resistance | 7/10 — Very good — non-combustible; hot strength/softening remain below high-silica/quartz/ceramic fibers. |
| Impact / penetration resistance | 6/10 — Good — similar impact behavior to E-glass with improved durability in corrosive environments. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically insulating with low thermal conductivity. |
| Specific tensile strength | 3/10 — 3/10 | 923.1 kN·m/kg | Family estimate |
| Atmospheric durability | 8/10 — Very good — improved acid/corrosion durability versus ordinary E-glass; retained properties still depend on sizing and matrix barrier quality. |
| Sustainability (CO₂e) | 9/10 — 1.44 kg CO₂e/kg fiber — Low emissions — data quality: High |
