    Radiation Cross Linked Fiber Reinforced 3 Layer Heat Shrinkable Sleeve For Corrugated And Spiral Drainage Pipe Joint

    INTRODUCTION
    3Layer Fiber reinforced PE heat shrinkable tape (sleeve) is composed of cross-linked polyethylene back, a middle layer of fiber and special heat melt adhesive an. The 3 layer reinforced sleeve gives better shrink ratio, and better strength. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated.

    Fiber reinforced products
    Application area:
    It is mainly used for Hollow wall spiral pipe, corrugated pipe and metal reinforced corrugated spiral pipe etc.
