Halogen-free Low Smoke and Low Halogen, the Difference Between Low Smoke Flame Retardant Cable

Halogen-free Low Smoke and Low Halogen, the Difference Between Low Smoke Flame Retardant Cable

Flame-retardant cable has slowed the spread of flame along the cable, so that the fire does not expand, because of the low cost, is currently a large number of fire-resistant cables used in a variety of species. Whether it is a single cable or bundle laying situation, when the cable burns, can make the flame spread to a certain extent, so as to avoid the cable fire delayed combustion brought about by a huge disaster, and thus enhance the level of cable line fire.

Halogen-free low-smoke flame retardant cables, etc.

The halogen-free low-smoke cable not only excellent flame retardant performance, and the composition of the low-smoke halogen-free cable raw materials in the presence of halogen, in the burning process corrosive, less toxic, will produce a very small amount of smoke, thereby reducing the human body, instruments, equipment and other harm caused by the fire in a timely manner to facilitate rescue. Although the halogen-free, low-smoke flame retardant cable is excellent in terms of flame retardancy, corrosion resistance and low smoke concentration, its mechanical and electrical properties are slightly lower than those of ordinary cables.

Low halogen, low smoke flame retardant cables.

Low-halogen, low-smoke flame retardant cable hydrogen chloride emission, smoke concentration indicators are in between flame retardant cable and non-halogen, low-smoke flame retardant cable. Therefore, the use of halogen-containing polymers can be considered in the design and manufacture of highly reliable cables to reduce the amount of hydrogen chloride released from the cable and reduce its level of environmental pollution. Low Halogen cable materials also have halogens present, but at very low levels. This cable has not only good flame retardant performance, but also less smoke emission during combustion and low hydrogen chloride emission.

Because of its excellent flame retardancy and smoke suppression, it is suitable for places that require high fire resistance requirements. The low-halogen, low-smoke flame retardant cable is usually processed by using polyvinyl chloride (PVC) as the substrate, with high-efficiency flame retardant, HCL absorber and smoke suppressant. Its main advantage is that it has excellent temperature and radiation resistance, and it also overcomes the shortcomings of ordinary PVC materials, which are prone to cracking. Therefore, this flame retardant material significantly improves the burning performance of general flame retardant PVC material.
