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.
