CONDUCTOFOL ® 2159

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

Format
Rolls maximum width 1000 mm
Tape from 6 mm width upward
Standard 9, 12, 15, 20 mm

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.

Additional Information
