Heat shrink sleeve T3155 automotive

HEAT SHRINK SLEEVE IN POLYOLEFIN SHRINKAGE 3 ÷ 1 AUTOMOTIVE

The T3155 sleeve is a flexible heat shrink sleeve. The high shrinkage ratio makes this sleeve is suitable to be used for the protection of particularly irregular objects due to high dimensional differences. Ideal in all applications where a high degree of protection is required, the T3155 sleeve is particularly suitable for use in the “Automotive” sector.

  • Shrinkage ratio 3:1: the sleeve shrinks 3 times with respect to the initial diameter
  • Available diameters: from 1.6mm to 39.0mm
  • Operating temperature: -55°C  to +125°C
  • Compliant with Standards: UL 224, VW-1, ASTMD2671, MIL-DTL-23053/4, IEC 93, IEC 243

Approval: File 305771

Heat shrink indication

  1. When shrinking the heat-shrinking sleeve, use equipment made for this specific operation such as, for example, guns or hot air tunnels.
  2. Shrink the sleeve starting at one end, the most critical part, and then proceed slowly to the opposite end. This method avoids the formation of air bubbles between the inner wall of the heat shrink sleeve and the object it covers.
  3. In the event that the object to be covered is made of metal or a good heat conductor, it is advisable to preheat the object to avoid “cold areas”, so as to allow a perfect and soft adaptation of the heat-shrinking sleeve.
  4. In order to avoid overheating of the heat shrink sleeve, ensure a regular heat distribution. Excessive overheating of the material during the shrinking process can cause bubbling, discoloration and in some cases even breakage of the heat shrink sleeve.
