8MIL Enhanced Polyethylene Encasements

VB3 Enhanced Polyethylene is the newest addition to our lineup. AA Thread's VB3 Enhanced Polyethylene is a 3-layer co-extruded film. The film not only createsa barrier between corrosive soil and the pipe but is infused with an anti-microbial biocide as well as a volatile corrosion inhibitor (VCI), giving this wrap further corrosion fighting capabilities than standard wraps. It also meets or exceeds all of the ANSI, AWWA, and ASTM standards required for Polyethylene Encasements.

The anti-microbial additive fights anaerobic corrosion caused by sulfate reduing bacteria. Thisbacteria is the most important microbe responsible for anaerobic corrosion on buried ductile iron pipe systems. The biocide in our wrap will prevent the growth of the bacteria on the pipe system.

The VCI mixes with any corrosive liquids that might seep between the wrap and the pipe and neutralizes them. Our test results have proven this to be very effective.

  • Multi-Layer Co-Extruded LLDPE
  • Anti-Microbial Biocide Additive
  • Volatile Corrosion Inhibitor (VCI) Additive
  • Greater Protection Over Standard Wraps
  • Meets ANSI/AWWA C105/A21.5
