Comparative overview
PVA fiber — Flame-retardant PVA
Strengths: Flame-retardant organic reinforcement with good textile processability and dielectric behavior.
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 functional PVA, above commodity fibers but not ultra-high-performance pricing. |
|---|---|
| EM transparency | 9/10 — Excellent — electrically insulating and RF transparent. |
| Temperature / fire resistance | 4/10 — Moderate — flame-retardant formulation improves behavior, but organic decomposition limits hot structural use. |
| Impact / penetration resistance | 4/10 — Moderate — moderate textile toughness; not a primary high-velocity reinforcement. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically insulating with low thermal conductivity. |
| Specific tensile strength | 2/10 — 2/10 | 692.3 kN·m/kg | Family estimate |
| Atmospheric durability | 3/10 — Low — hydrophilic PVA can absorb moisture; flame-retardant additives and coatings may further influence outdoor ageing. |
| Sustainability (CO₂e) | 8/10 — 4.00 kg CO₂e/kg fiber — Low emissions — data quality: Low |
