TAT-125
Flexible, adhesive-lined, polyolefin
heat-shrinkable tubing
TAT-125 is an adhesive-lined, flexible, must withstand flexing or other application to form a positive
thin-wall, heat-shrinkable tubing. physical abuse. Because both tubing environmental seal. The adhesive
It provides one-step electrical and adhesive are flexible, the will adhere to a wide variety of
insulation and moisture sealing for moisture seal is resistant to bending plastics, rubbers, and metals,
a wide variety of applications. of the substrate. including PVC, polyethylene,
neoprene, lead, and steel.
TAT-125 is especially suitable for The thin adhesive lining of TAT-125
applications where the moisture seal melts and flows with the heat of
