Manufacturer page / TDSDescription
Glass family: E / proprietary. Product form: Roving. Scope: Thermoplastic composite reinforcement. Official product-family listing.. Official source: GF-NITTOBO-COMP
Comparative overview
Glass fiber — Thermoplastic-compatible E-glass
Strengths: Low-cost, scalable reinforcement optimized by sizing/form for compounding, injection molding and long-fiber thermoplastics.
When to use: Select for high-volume automotive, electrical and industrial molded parts where processability and cost dominate.
Key tradeoffs: Lower continuous-fiber structural efficiency and poorer specific properties than premium fibers; final performance is strongly length/orientation dependent.
Qualitative ratings (1–10 scale)
| Relative cost | 2/10 — Low — E-glass base with thermoplastic-compatible sizing/process control. |
|---|---|
| EM transparency | 8/10 — Very good — intrinsic glass remains dielectric; final behavior depends on thermoplastic matrix and fiber fraction. |
| Temperature / fire resistance | 7/10 — Very good — non-combustible fiber, although the thermoplastic matrix usually controls heat/fire response. |
| Impact / penetration resistance | 6/10 — Good — glass strain plus a tough thermoplastic matrix can give good damage tolerance; the score is fiber-level only. |
| Electrical / thermal conductivity | 1/10 — Very low — electrically insulating with low thermal conductivity. |
| Specific tensile strength | 3/10 — 3/10 | 930.2 kN·m/kg | Family estimate |
| Atmospheric durability | 7/10 — Good — the glass itself resists UV, but moisture, hydrolysis of sizing and thermoplastic interface ageing can reduce retained composite properties. |
| Sustainability (CO₂e) | 9/10 — 1.44 kg CO₂e/kg fiber — Low emissions — data quality: High |
