CALMICAGLAS ® 0893

CALMICAGLAS ® 0893 consists of mica paper based on a uncalcined muscovite, glass cloth and thermosetting epoxy novolac.  CALMICAGLAS ® 0893 is a very flexible glass mica paper combination, which can be taped even on tight bends.   CALMICAGLAS ® 0893 gives a higher resin flow during pressing process compared to type CALMICAGLAS ® 2005 which allows the insulation of complex shapes.  Excellent dielectric, thermal, mechanical and chemical properties are obtained after pressing.

Applications

CALMICAGLAS ® 0893 is used e.g. for the insulation of coils and bars  of low voltage machines.  Moreover CALMICAGLAS ® 0893 can be used for manufacturing of moulded parts such as commutator caps or wound tubes and cylinders.   CALMICAGLAS ® 0893 is supplied interleaved to prevent sticking of layers
