Adhesive lined shrink tubing is a 3:1 flexible tubing offering the advantages of integral, adhesive-lined construction. The tubing is made from flexible polyethylene with an internal layer of special thermoplastic adhesive. The heat-shrinkable outer wall is selectively cross-linked, while maintaining the high flow and excellent adhesion of the inner sealant liner. When heated in excess of 121ºC (250ºF), the tubing rapidly shrinks to a skintight fit, forcing the melted adhesive lining to flow and cover the substrate. The adhesive forms a flexible bond with a wide variety of rubbers, plastics and metals. Upon cooling, the adhesive solidifies, forming a permanent, non-drying, flexible and water resistant barrier. Adhesive reflow will occur at temperatures above 80ºC (176ºF).

S
afety and Environmental Protection]
: Wonderful heat-shrinkable tubes are UL and CSA certified, RoHS compliant, free of formaldehyde
(HCHO), heavy metals and other harmful substances protecting you and your family from toxins
[The rubber liner has good sealing performance] Our heat-shrinkable tube has the advantages of good electrical insulation, good sealing, corrosion resistance and high temperature resistance. Anti-aging, tough, not easy to break.
[Easy and fast]
You only need to heat it evenly with a hot air blower or a candle to make it shrink. It is a 3:1 heat shrink ratio and will shrink to the original 1/3.
[Versatile and DIY Helper]:
High-quality heat shrink tubing, they can be used for solder joint protection, group of lines marking, resistance electric capacity reason protection etc. Note: Make sure temperature of your heat gun is up to 212℉(Fahrenheit), then glue inside will soften and seal the connection.
[Great Advantages ]: Our heat-shrinkable tube are with glue lined which has the advantages of good electrical insulation, good sealing, corrosion resistance and high temperature resistance. Anti-aging, tough, not easy to break.
[A wide range of applications]

About 3:1 Ratio Heat Shrink Tubing
What is it good for?
Industrial adhesive lined shrink tubing offers excellent protection for electronic components, wire splices, wire bundles and harness breakouts. Automotive, truck and marine wiring splices and harness breakouts are quickly and easily protected from harsh environments.
What is Shrink Ratio?
Industrial adhesive lined shrink tubing has a 3:1 shrink ratio. This means that the starting diameter of the tubing as supplied is 3 times the fully contracted diameter if allowed to completely shrink. The wall thickness of the tubing is proportional to the percentage of shrinkage.
