Use this wrap with heat-shrink tubing to create a moisture-resistant seal. Apply it like tape around wire and cable, and slide the tubing over the wrap. The wrap melts when tubing is heated and bonds to the underlying surface.

Butyl rubber wrap seals larger gaps than TPE rubber wrap, so it’s better for protecting irregular shapes or items with deep grooves.

TPE rubber is better for electrical insulation than butyl rubber. It withstands higher temperatures.

Dielectric strength is the maximum voltage a material can handle before it starts to breakdown. The higher the dielectric strength of a material, the better it is for preventing electricity, heat, or signal from dissipating from wire and cable.
