Description 竊�/span>

Featuring excellent anti-high temperature and high mechanism strength竊�/span>non-halogen,smokeless.

Application
It is used for filler of the flame-retardant, fire-resistant, LSOH flame-retardant, fire (oxygen) separated, LSLH flame-retardant cables.

Function of the filler string in the flame-retardant cable component
1��/span>It ensures that the cable is of good roundness.
2��/span>It can improve flame-retardant class of the cable when use filler with high oxygen index.
3��/span>It can fix the cable core in a stable position.
4��/span>It can increase cable’s tensile strength.

Requirement to filler used for the flame-retardant cable
1��/span>It mustn't absorb the moisture.
2��/span>Its operation temperature should be the same with that of the cable.
3��/span>It should not pollute the environment and do harm to human body in process of wrapping.
4��/span>It should have good tensile strength and certain elongation.
