SynShield® – Copper & Aluminium Foils SynShield® Type 4

Copper foil fully covered with SynTherm® insulating material.

SynShield® copper conductor is a flexible copper foil laminated with various insulating materials.

SynShield® is just perfect for winding. There are two production methods for SynShield®:

  • The insulation is applied during a special process without adhesive. Thsi process guarantees excellent soldering behaviour and a low total strength.
  • The insulation is applied with the aid of an adhesive.

Formats:

  • with soldering gap
  • types without adhesive: PET films
  • types with adhesive (SynTape®):
    PET films
    aramid papers
    PI films
