Product Details

Product Description
This mica tape is built up with mica as base material and epoxy adhesion as binder to bind plus reinforcing material of alkali free glass cloth on surface. It is perfectly flexible under the normal temperature. After processed by vacuum pressure impregnating technology (VPI) together with impregnated compatible resin, it can be solidified into mica tape.

Product Feature
The tape adhesion must be distributed homogeneously without bubble, pore, adhesion, lami-nation, foreigh matter, crack of mica paper, reeling out of glass cloth, loosening of tape coiling, etc.

Application
Owing to the high mica content and excellent electrical function, it is noted as the ideal insulation material for the large and medium size high tension electrical machinery with VPI technology.
