Wave-X Heat, from ARC Technologies, is a shrinkable tube absorber, designed to integrate with wire and cable assemblies, neatly sealing junctions and connector interfaces while absorbing unwanted EMI interference.
The device is slipped over the cable or connector, heat is applied and the absorber shrinks to conform.
It has an inner layer of thermoplastic polymer, blended in exacting ratios with magnetically permeable metal powders. The outer layer is a high dielectric thermoset polymer. When moderate heat is applied the product shrinks to about a third.
