PTFE / FEP dual heat-shrinkable tubing

The optimum solution for complete insulation

Our dual heat-shrinkable tubing covers diameters from 0.00 to 25.15mm as standard. Our dual heat-shrinkable tubing is composed of a PTFE heat-shrinkable tubing with an inner core made of FEP. The inner part of the heat-shrinkable tubing liquefies in the course of the shrinking process, thus creating an optimal and permanently perfect seal around the object. The most common application field of our dual heat-shrinkable tubing are the so-called heat-shrinkable sleeves. In this case, the dual heat-shrinkable tubing is used to permanently insulate and seal cable connections. Level sensors can also be permanently protected from aggressive media by means of our dual heat-shrinkable tubing. Our standard products cover object diameters from 0.00-25.00mm. Customer specific dimensions are manufactured upon customer request.

Overview of the most important properties of our dual heat-shrinkable tubing:

  • temperature resistant between -100°C and 205°C
  • food-safe
  • All-round chemical resistant
  • UV-resistant
  • anti-adhesive
