About 4:1 Ratio Heat Shrink Tubing

• 【4:1 RATIO RAISE EFFICIENCY】: heat-shrink tubing 4:1 it will shrink up to 25% of original rapid contraction that solve the problem that the 2 :1 Ratio heat shrink tube is not tight enough after shrinking.and can be used for the contraction protection on of irregular shape objects.
• 【ADHESIVE LINED&DUAL WALL】: The shrink tube with hot melt adhesive on the inner wall.After shrinking, the inner lining glue will completely seal the materials at the two ends of the connection, so as to achieve better waterproof and insulating Sealing effects.
• 【HIGH PROTECTION AND EASY TO USE】 :Our shrink tubing it very soft and elastic can effectively flame retardant , excellent Insulation Sealing, good viscosity ,Dual wall thickness and easy to use can be shrunk by heating with hot air gun.
• 【PE HIGH MOLECULAR ELASTIC MATERIAL】: Our heat shrinkable tube has passed UL and CSA certification, meets RoHS requirements, which has the advantages of good electrical insulation, Waterproof, Wear-Resistant,Flame Retardant,good sealing,corrosion resistance, oil-proof etc.
• 【VARIETY OF SIZES】The 4:1 shrink tube data shown in this product are the inner diameter of the heat shrinkable tube the round state. not the measured data of the outer diameter and flattened .We have included 4 most commonly used diameters ranging from 1/4" to 1"
• Product Description

  	Adhesive Lined and Dual Wall marine grade heat shrink tubing provides better rigidity and abrasion resistance. Dual wall shrink tubing design has the increased ability to stand up to wear and tear. This is a waterproof shrink tubing with the internal adhesive layer. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat activated glue strongly adheres to wires, terminals or any other surfaces. When adhesive flows, it pushes the air out and fills any gaps between the wire and the tubing, which makes the connection waterproof.
  Feature Sealing, waterproof, strain buffering, outer self extinguishing ,Dual wall thickness, while maintaining flexibility, improves mechanical protection strength with good viscosity .Our heat shrink tubing it very soft and elastic can effectively retardant , excellent Insulation performance.
  	Special Heat Shrink Tubing are excellent to seal lugs and other wiring connections you wish to secure and keep dry.Works great for large power wire ,made up some new wiring for you project. A project like some requires a couple different sizes and colors of heat shrink tubing and a proper adhesive color coded (red = positive, black = negative) sealing of the crimped wire and connector

A wide range of applications of Shrink tubing
