To provide the optimal solution for each application, Covalence HSP offers a range of products based on an irradiated crosslinked polyethylene carrier, combined with a hotmelt or mastic coating.

The main purpose of the crosslinked carrier, called ‘backing’, is to provide a strong barrier against electrical current, permeation and mechanical forces.
Covalence HSP has over 40 years of experience in the development and manufacture of heat-shrinkable products.

Two-layer and three-layer constructions complement wide range of pipe coatings

Top quality hotmelt, copolymer coated sleeves resist elevated pipe operating
temperatures and soil stresses on all pipe diameters

Mastic-coated sleeves balance performance, economy and ease of installation

Three-layer sleeves with epoxy primer and hotmelt copolymer have excellent
resistance to both cathodic disbondment and hot water immersion

Fiberglass-reinforced sleeves withstand the high stresses of directional drilling

Self-healing adhesive flow automatically repairs minor mechanical damage

Dimpled backing providing a "permanent change" indicator for application of heat.
