How is SureSeal constructed?
SureSeal is constructed by applying two layers of tough cross-linked polyethylene around six streams of sealant. Conductor strand is fed into an extrusion head where the insulation and sealant are applied at the same point to the conductor. A vacuum pulls the insulation and sealant down onto the wire strand to insure a good grip, eliminating potential shrink back issues. The result is a totally bonded construction that provides equal protection around the entire cable. Since the insulation totally encapsulates the sealant, you get cleaner stripping. As well, there is no chance that sealant can migrate, or “leak down”, into the strand where it could reduce sealing capability from external damage.
