Class F Glass Cloth Mica Tape

Description
Class F Glass Cloth Mica Tape (equivalent to Samicapor® 366.56-10, 366.58-18; 366.55-20) is a low bonder content mica tape, constructs of mica paper bonded to woven glass fabric on one side with the modified epoxy resin.
This Mica Tape shows excellent flexibility, good taping properties, high thermal resistance, excellently physical and electrical properties after VIP treatment.

Application
Glass Cloth Mica Tape can be used for the main insulation of low and high voltage machine coils thermal rating
class F(155°C) which are exposed to extreme environmental stresses for VPI processing.
