Heat Shrink Tubing Detail:
-[Safety 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] Shrink tube are mainly used for industrial, ship, wire links, anti-rust and anti-corrosion protection of solder joints, and audio and electrical DIY. Wire ends, harnesses, electronics protection and insulation treatment, fitness equipment parts and steel structure surface protection and so on.
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.
-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).
