Guide to choice and use: how to choose the thermoretractable sheath ?
by ratio, thickness, with resin, size, color, packaging.

Choice by coefficient of retreint (ratio 2:1 3:1 4:1 6:1), thickness, with or without adhesive, colors, size, packaging by reel, bar, sleeve, meter.

produit thermorétractable 3 M raychem tyco canusaHow to choose and use the thermoretractable sheath using the thermoretraction guide?

  1. Choose the type of wall of the sheath according to your use, from the thin and flexible wall to the thick and watertight wall from 0.33 mm to 4.3 mm (see detailed sheets for finished thicknesses).
  2. With or without adhesive, to ensure perfect sealing, choice according to the operating temperature 105°C, 110°C, 135°C, extinguishable car sheath.
  3. Then choose the retreint coefficient (2:1 to 6:1), this corresponds to the ratio between initial and minimum diameter, for example a 12/4 mm sheath , Ø 12 mm initial front retracted and Ø 4 mm at the minimum retracted, corresponds to a retract of 3:1.
  4. As a reminder, if you are looking for the sheath circumference, it is enough X the diameter by 3.14, for example a sheath with a diameter of 12.7 mm at a circumference of 38.93 mm
  5. You then have a color choice (black, blue, red, green, white, yellow, brown, grey, transparent, yellow green, orange)
  6. Then choose the packaging according to the types, sleeves, tubes, bars, coils, dispenser boxes, assortment box without adhesive, assortment box with adhesive, black thermoretractable sheaths and colors in meter
  7. On request large diameter sheath up to 1000 mm
  8. Attention all the dimensions indicated are the useful inner diameters, and NOT flat, see our table of equivalences, for the conversion of dimensions diameter to flat

Heat-retractable, thin-walled sheath (small)

Applications: industrial, tracking, identification, dressing, electrical insulation, cable protection, waterproofing, insulation of welded points, insulation and shell protection and connectors, light gain. . The transparent thermoretractable sheath protects, isolates or seals while clearly showing the support or marking mark.

How to put in place the thermoretractable sheath (thermal shrinking)

  1. Cut the desired length, foresee a longitudinal narrowing of 5-7 % (tube length)
  2. See the technical data sheets to know the retreint temperature of the sheath, it is best not to use flame, but rather a flame gun thermal or suitable oven, we offer a range of gun hot air suitable for the installation of thermoretractable sheaths and products, no electricity, think about gun wireless heating
  3. Heat evenly over the outer diameter and over the entire length of the sheath, not overheating, the sheath will lose its characteristics, let the sheath cool slowly.
