Special Purpose Heat Shrink Tubing

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 Dimensions
