      strong cross film self-adhesive waterproofing membrane
      
							
      Product introduction:
      The rapid response sticky Beifang newly developed strong cross film self-adhesive waterproofing membrane is composed of a cross laminated high density polyethylene (HDPE) special self-adhesive waterproofing membrane with high performance, cold construction strong film and high quality polymer adhesive rubber asphalt technology with a special compound and into, with dimensional stability, excellent thermal stability, anti ultraviolet performance and bidirectional tear resistant properties.
      
							
      Execution standard: GB/T23457-2009 “Pre-applied and wet installed self-adhering waterproof sheets”

      1, a nail rod tear strength, a nail rod water tightness is more excellent than ordinary mask.
      2, with strong cross film production of self-adhesive membrane than ordinary waterproof coiled material on the nails roofing fixing piece of bond stress is stronger, and more high tear strength. Because the nails through the strong cross membrane, vertically and horizontally staggered film to nail a wrapped function and the stress is the same, not tear. While the ordinary film is high longitudinal strength, transverse strength is very low.
      3, excellent tensile strength and two-way tear resistance, good weatherability
.
      4, good dimensional stability, not wrinkle, waterproof effect is more reliable.
