Natural Mica is formed by flat six-sided monoclinic crystals
with a remarkable cleavage in the direction of the large surfaces, which permits
them to split easily into optically flat films, as thin as one micron in
thickness. When split into thin films, they remain tough and elastic even at
The crystal structure of MICA is silicon as basic
skeletal structure. Its stratified combination is connected by potassium atoms
and is separated by cut off combination at this place due to the binding force
of potassium and oxygen is very weak.
Mica in its natural form has limitations as to it
process-ability and versatility and also very high cost for large sheets. To
acquire the flexibility, adaptability in consideration of cost factor, Splitting
Micanite is a product in such a form that it is available in composite sheets
and a variety of shapes, thickness and sizes.
Paper Laminate is a sheet material made from Mica Paper. Mica Laminate is available in Sheet and Tape form with
various configurations of binders & process as per thermal class ratings, and is
used for insulators. It has a dielectric strength of 450~900 volts per mil. The
properties of paper Micanite are highly reproducible in sheet form.
insulated heaters are constructed of nickel-chrome resistance wire wound
uniformly around the mica winding card and insulated by select quality mica
either natural Mica or Heat Resistant Mica Laminate, for a maximum
operating temperature of 550 °C. To ensure trouble free operations, the resistance ribbon joints
and terminals are either spot welded or riveted.
The term Processing applies to
various processes, such as cuttings, stamping, punching, Forming, Bonding
and Molding of natural sheet mica, Mica Composites or Mica Laminates
to a specified size, shape, thickness and design within close dimensional
tolerances for electrical and electronic end-uses.
