- **Strength:** ~120 MPa typical (SCF nylon); excellent melt flow and dimensional stability
- **Base resins:** PA6, PA66, PA12, PBT, PET, PPS, LCP, PEEK, PP
- **Best for:** thin-wall, fine-detail, appearance-critical, high-volume injection molded parts (gears, connectors, housings, electronics, under-hood) where moderate loads, fast cycles and low unit cost matter
- **vs LFT:** SFT = better flow / lower cost / fine detail; LFT = higher strength, impact and fatigue for structural metal replacement

### 2. Conductive / Antistatic Engineering Plastics
