Nomex/Kapton/Nomex spiral wound tubes and end caps offer superior properties for the most demanding application such as:

  • Dielectric strenght
  • Mechanical strenght
  • Tensile strenght
  • Thermal class
  • Chemical resistance

They are spiral wound by using a high temperature resistance adhesive.

Tubes and end caps can be produced also by using not calendered Nomex 411 in order to improve wicking during impregnation process.

These tubes and caps are often used in automotive industry as a slot liner insulation or to guarantee a perfect insulation to splices, motor leads termination, junction.

They are integrated in UL system to +220°C.

For automotive applications, Politubes also supplies tubes and ultrasonic welded end caps produced with a combination of Nomex and heat shrinkable polyester type Mylar HS by DuPont.
