Special Purpose Heat Shrink Tubing, WRSJD

Model: WRSJD

Adhesive lined cross-linked polyolefin heat shrink tape

WRSJD is adhesive lined cross-linked polyolefin heat shrink tape specifically designed for sealing joints on spiral, flexible or flat oval ducts used in heating, ventilating, air conditioning and exhaust recovery systems.

Features

Shrink ratio: 1.4:1
Eliminating air leakage in vacuum and ventilation systems
Sealing against moisture ingress and other contaminants
Strong adhesive bonding to galvanized steel, aluminum and stainless steel
Effective and reproducible sealing ensures resistance to bending, vibrations and other mechanical stresses over a wide range of temperatures

Application process is quick, simple and clean
Continuous operating temperature: -45℃～125℃
Fully shrink temperature: 120℃
Color: black, red, green, yellow
