HZDFR4100
Thermoplastic low-smoke halogen-free flame-retardant cable compound
Overview
HZDFR4100 is a 90 °C thermoplastic low-smoke halogen-free flame-retardant cable compound. Colourable and polyolefin-based, it emits no halogen acid or corrosive gas and contains no heavy metals; cables with a sound design can pass IEC 60332-3 Category B bundled-cable burning. It is widely used as the outer sheath of marine, power, control, communication, building and instrument cables, with an excellent cost-to-performance ratio.
Key features
- Thermoplastic — no irradiation cross-linking required
- Low-smoke halogen-free, no corrosive gas or heavy metals
- Supports IEC 60332-3 Category B bundled burning
- Good mechanical, processing and flame performance
- Versatile sheathing for many cable types
