FOPS - Foam Injection Hole Sealing

FOPS - Foam Injection Hole Sealing
Colors: Black
Backing Binder: PE
Total Thickness: 1.55MM
Category: Heat Shrinkable Pipeline Coatings

FOPS is a watertight and mechanically strong seal of foam-holes in standard, oversized or heat-shrinkable PE casings of thermally insulated pipes. It consists of a thick-walled, radiation crosslinked, high density polyethylene with Thermochromic Change Indicator and a high shear-resistant thermoplastic adhesive.


FOPS is used for the sealing of foaming injection holes in the oversized or heat-shrinkable casings of insulated pipe joints. It is used in conjuction with a FOPS plug with or without mastic filler to fill the foam injection hole. For added integrity, FOPS may be installed over a PE-welded plug.
