Adhesive Lined Heatshrink

Adhesive lined heatshrink tubing provides enhanced environmental sealing and strain relief for electrical connections. Featuring an internal layer of heat-activated adhesive, this polyolefin tubing offers a higher shrink ratio (typically 3:1) compared to non-adhesive variants. Upon heating to approximately 120°C, the tubing shrinks while the adhesive melts and flows, creating a robust, moisture-resistant seal. It is available in various diameters and colours, often with flame retardant properties, and is supplied in specific lengths.
