FR6618MAUV2

Low-Smoke Halogen-Free Flame Retardant Polyolefin Sheathing Compound

- Good processability, suitable for processing on general-purpose extruders.
- Excellent flame retardancy: oxygen index ≥ 30%, passing single vertical combustion.
- Halogen-free and environmentally friendly: halogen acid gas content ≤ 5 mg/g, combustion gas pH ≥ 4.3, conductivity ≤ 10 μs/mm.
- Good weather and UV resistance: after xenon arc lamp aging (1000h), the rate of change of tensile strength and elongation at break is within ±30%.
- Low coefficient of friction after cabling (≤ 0.25), providing a smooth sheath surface.
- Good thermal stability: thermal deformation ≤ 20% at 90℃, heat shrinkage ≤ 3% at 85℃ for 4 h.

This product is a low-smoke halogen-free flame-retardant polyolefin cable compound. Its color can be customized according to customer requirements, and it is primarily suitable for the following applications:
1. Outer sheath of drop-wire (butterfly) cables, meeting single vertical combustion requirements;
2. Various low-smoke halogen-free colored sheaths and color stripe (identification stripe) applications, meeting customers’ multi-color and color-identification requirements.
In addition, this product features a low coefficient of friction after cabling (≤ 0.25) for a smooth sheath surface, and good weather/UV resistance (rate of change of tensile strength and elongation at break within ±30% after xenon lamp aging for 1000h), making it also suitable for applications with surface smoothness and weather/UV resistance requirements.
