Polyken 939 Pipeline Coating Filler Tape
The Polyken filler tapes are designed as an underlying filler material prior to the application of Polyken coating systems and Covalence Heat Shrinkable Products. The elastomeric formulation is very conformable, making it ideal for filling in transition areas around tees, ells, valves, specials, welded and coupled field joints. The filler tapes maintain flexibility over a wide temperature range and under various conditions encountered in the field.
Product Features and Benefits:
· Flexible under various field conditions
· Easy and simple application
· Conformable and moldable
· Compatible with Polyken coating systems
The #939 is a thick mastic-like butyl rubber filler designed to fill and smooth transitions areas.
