Kuraray ? PVA-SOL
Manufacturer page / TDSDescription
Water-soluble PVA fiber available in grades dissolving from low temperature to boiling-water conditions.. Product form: Fiber / filament product family. Thermal/service data: Dissolution temperature depends on grade. Official source: EX-PVA-KURARAY
Comparative overview
PVA fiber — Water-soluble PVA
Strengths: Controlled water solubility enables removable/dissolvable textile functions and specialized processing.
When to use: Select for dissolvable support, temporary textile functions and specialized industrial processing after validating dissolution conditions.
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 — functional water-soluble specialty fiber; cost reflects controlled dissolution grades. |
|---|---|
| EM transparency | 9/10 — Excellent — electrically insulating and dielectric. |
| Temperature / fire resistance | 1/10 — Very low — water solubility and low heat resistance make it a sacrificial/process fiber. |
| Impact / penetration resistance | 2/10 — Low — not intended as permanent impact or penetration reinforcement. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically insulating with low thermal conductivity. |
| Specific tensile strength | 1/10 — 1/10 | 384.6 kN·m/kg | Family estimate |
| Atmospheric durability | 1/10 — Very low — designed to dissolve or strongly interact with water, so it is unsuitable for persistent outdoor exposure without a complete moisture barrier. |
| Sustainability (CO₂e) | 8/10 — 4.00 kg CO₂e/kg fiber — Low emissions — data quality: Low |
