POROFOL ® 2076, ME 2075

POROFOL ® 2076, ME 2075

POROFOL ® 2076 consists of highly absorbent mica paper based on uncalcined muscovite and PET-film as a carrier.  The binder is a hardener-free epoxy resin.

POROFOL ® 2075  in addition contains an accelerator for impregnating resins based on epoxy anhydride.

POROFOL ® 2076 an ME 2075 are flexible tapes suitable for hand and machine taping,  In spite of the PET-film a great number of layers can be impregnated in a short time due to the high porosity of the mica paper.  Mechanical and electrical properties of the final insulation mostly depend on the impregnating resin used.

Applications

POROFOL ® 2076 and ME 2075are used in VPI-systems for continuous insulation of coils and bars for low and high voltage machines as well as for interlayer insulation in in dry type transformers.

Format
Rolls maximum width 1000 mm
Tapes from 10 mm width upward
