Feature:
It has characteristic of strong moisture absorption, big expansion rate and quick expansion velocity. Small resistance can make cable has semi-conductivity. and can buffer and weaken the electrical field strenath effectivelv. High mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables. It is heat-resistant and can bear hich instant temperature. Cable with this product can keep stable performance.

Storage:
It should be stored in dry house, kept away from source of fire and not to be exposed to the sunshine. Also itshould avoid moisture and mechanical damage during storage and transportation. The shelf life is 6 months after themanufacturing date.
