Comparative overview
PVA fiber — High-strength PVA
Strengths: Good adhesion to cementitious matrices, toughness and crack control at moderate cost.
When to use: Select for cement/rubber reinforcement, crack control, protective textiles or industrial yarns according to the specific grade.
Key tradeoffs: Limited heat resistance and moisture-sensitive behavior; not a substitute for carbon/aramid in high-load structural composites.
Qualitative ratings (1–10 scale)
| Relative cost | 4/10 — Low–moderate — specialty high-strength PVA with industrial-scale cement/rubber applications. |
|---|---|
| EM transparency | 9/10 — Excellent — electrically insulating and generally dielectric. |
| Temperature / fire resistance | 2/10 — Low — organic PVA has limited heat/fire capability despite strong ambient mechanical properties. |
| Impact / penetration resistance | 6/10 — Good — high strength, crack bridging and abrasion resistance provide useful low-velocity toughness, but limited ballistic evidence. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically insulating with low thermal conductivity. |
| Specific tensile strength | 5/10 — 5/10 | 1384.6 kN·m/kg | Family estimate |
| Atmospheric durability | 4/10 — Low–moderate — high-strength PVA is moisture-sensitive despite good chemical bonding; humidity protection is required for stable long-term properties. |
| Sustainability (CO₂e) | 8/10 — 4.00 kg CO₂e/kg fiber — Low emissions — data quality: Low |
