Heat-Shrinkable Water-Blocking System
Designed to provide consistent sealing for cable bundles and the back of connectors. The wires in the bundle are placed within the channels of a specially formulated hot-melt adhesive profile, and then covered by dual wall, heatshrinkable tubing with a flame-retardant radiation cross linked outer wall and hot-melt-adhesive inner wall. When the tubing is heated, the hot-melt adhesive melts and the tubing shrinks, forcing the molten adhesive to fill all the voids within the wire bundle and tubing. The result is a solid plug of adhesive molded around each wire in the bundle, creating a moisture-resistant seal.
Minimum shrink temperature: 80°C [176°F]
Minimum full recovery temperature: 110°C [230°F]
