Applications
- Power, control, and instrumentation cable jackets (LSZH/HFFR)
- Molded plugs and strain relief boots for safety-critical lines
- Indoor public spaces, transportation, and industrial facilities
Typical Grades
| Grade | Hardness | Key Performance | Processing | Typical Use |
|---|---|---|---|---|
| TPU-EX 90A FR | 90A | HFFR jacket, smooth surface, abrasion resistance | Extrusion | General LSZH cable jackets |
| TPU-EX 95A FR | 95A | High rigidity, tear & dimensional stability | Extrusion / Injection | Heavy-duty jackets, strain relief boots |
| TPU-EX 90A FR-LS | 90A | Low smoke formulation, matte finish option | Extrusion | Public-space and transport cables |
Note: Formulations can be tuned for flame test performance, smoke & acid-gas indexes, and surface finish. “Meet/comply” levels are subject to customer test methods.
Key Advantages
- Halogen-free flame retardancy with TPU flexibility and toughness
- Low smoke and low acid-gas potential (formulatable)
- Abrasion and tear resistance for long service life
- Matte or glossy finish achievable via die design
Processing & Recommendations
- Extrusion for jackets; injection/overmolding for strain reliefs
- Typical melt: 180–210 °C（by hardness & FR package）
- Drying: 80 °C × 2–3 h before extrusion
- Phosphorus-based halogen-free systems; specific FR packs selectable per target tests
