CONDUCTOFOL ® 2159 consists of mica paper based on calcined muscovite impregnated with resin and both sides are covered with a PET-film whereas one side is additionally coated with a special adhesive.  The adhesive on the thicker PET-film melts at temperatures above 100 ºC and conductors with CONDUCTOFOL ® 2159 can be glued together in a hot press.

Applications

CONDUCTOFOL ® 2159 is used e.g. for the insulation of rectangular copper conductors for low and high voltage coils

Storability

Minimum 24 months at 20ºC
Minimum 48 months at 5ºC

Processing Advice

Pressing conditions for preconsolidation:
Best bonding will be achieved at 160 ºC. In addition the adhesive on the PET-film improves bonding of the main insulation (VPI- or RR-system) to the conductor bundle. The conductor bundle covered with a release film is put into a hot press at 120 – 160 ºC and pressed for 1-5 minutes. Before opening the press is is recommended to cool down below 100 ºC.
