3:1 shrinkage with adhesive sealing, maximum protection performance
3:1 adhesive-lined colored heat shrink tubing features a dual-wall structure with an eco-friendly irradiated cross-linked polyolefin outer layer and a hot-melt adhesive inner layer. It complies with RoHS environmental standards and contains no harmful substances.
With outstanding core advantages, the 3:1 high shrink ratio offers wide adaptability. For example, a 15 mm tube shrinks down to only 5 mm, precisely covering most standard cable connectors.
The initial shrink temperature is 80 ℃, and the full shrink temperature is 110 ℃. It shrinks rapidly and evenly when heated. The hot-melt adhesive layer fully melts and bonds tightly to metals, plastics, rubber and other materials, forming a seamless sealing barrier with nearly zero water absorption.
It meets flame retardant standards, with an operating temperature range of -55 ℃ to 110 ℃, tensile strength ≥ 12 MPa, and elongation at break ≥ 400%.
It is aging-resistant and corrosion-resistant, not prone to cracking or falling off during long-term use.
Various color options enable circuit identification to avoid misoperation.
Full-scenario application with both protection and identification!
- For building electromechanical wiring: color-coded for error prevention, sealed against grout leakage.
- For automotive and photovoltaic applications: withstands high and low temperatures and harsh conditions to ensure stable circuit performance.
- For electronic equipment and household maintenance: quickly repairs insulation layers with sealing and moisture resistance.
Whether for industrial production, infrastructure projects or daily maintenance, it provides strong cable protection and improves construction and maintenance efficiency with its high shrink ratio, excellent sealing and clear identification.
