    2.stable anti-static( optional ): surface resistivity: less than 1 X 10 8 ohm.

    3.flame retardent ( FR grade can meet NFPA701, B1, B2, M2 standard )

    4.superior broken tensile strength and tear strength.

    5.extremely low air leakage rate of a hundred meter.

    6.endure the temperature variation(-30℃--70℃).

    7.more fold-resistant.

    8.low surface resistivity.

    9.environment friendly,no unpleasant odor.

    Cautions of using:

    1.The duct with different size should be selected according to the specific circumstances underground.

    2.The duct should be hoisted to straight and should make every ring forced uniformly to avoid the weight concentrated in part rings.

    3.The duct should be regularly checked ,timely repair of damaged can prolong its use life.
