Additional Covalence Products

A series of heat-shrinkable multi-layer sleeves that have high electrical resistance and low permeability, making them the optimal solution for corrosion prevention for steel pipelines and sealing of pre-insulated piping systems. The products consist of an irradiation cross-linked & stretched polyolefin backing with an adhesive laminated on in order to form the basic product. The adhesive may be either visco-elastic based mastic or co-polymer hot melt adhesives to match up with in-service performance requirements.
