Sumitube Dual Wall Heat Shrink Tubing

Sumitube Dual Wall Heat Shrink Tubing

Sumitube W3B2 is a dual wall, flame-retardant heat shrinkable tubing with meltable adhesive for the waterproofing of irregularly shaped objects. It has great tensile strength, elongation, dielectric strength, and fluid and corrosion resistance against bare copper. These attributes make it a perfect dual wall tubing for mechanical, electrical, and chemical applications, including the encapsulation of wire branches, insulation, and protection for wire joints as well. Sumitube W3B2 is SAE-AMS/UL/CSA recognized and features a thicker adhesive than Sumitube O2B2.

Sumitomo also offers Sumitube W3B2 (4X), which is very similar to their regular W3B2, however, they offer different sizing options and the 4X is only SAE/ UL recognized.
