High Voltage Electric Insulation and Fire Resistance Mica Sheet

High Voltage Electric Insulation and Fire Resistance Mica Sheet

Mica sheet
Mica sheet is mica lamination designed for providing fantastic electrical insulation at high temperature, which consist of approximate 90% Muscovite(or Phlogopite)and ten% temperature resistant silicone resin.

Excellent thermal resistance, muscovite mica keep insulation properties at 500ºC and phlogopite mica sheet resistant temperature up to 750ºC.
Superb electric powered insulation, typically the breakdown voltage is far more than 15KV/mm.
Exceptional flexural energy and effortless to be punched and machined.
Environmental risk-free. It is incombustible, asbestos and halogene free of charge and does not create harmful gases.

Thickness:.1mm .15mm .2mm-20mm
Measurement:one thousand*600mm 
Thickness beneath 2.0mm can be punched, although over 2.0mm can be machined by agreement.

No limitation below dry and space temperature.
By the mica paper, resin and homes, mica plates have adhering to varieties.

Rigid Mica Plate

YG-5660-H is a type of rigid laminated content, made of muscovite or phologpite mica paper with silicon resin.
They are known by its excellent thermal resistance, very good flame resistance, higher dielectric toughness, exceptional physical energy, and small smoke by heating.
The goods have been commonly utilised in the industries of household electrical appliances (clothing irons, hair dryers, toaster, kettles, cooking appliances, microwave ovens, air heaters), metallurgy(frequency furnace, intermediate frequency furnace, arc furnace), medical appliances, etc.
Flexible Mica Plate

YG-5660-S is a type of flexible laminated materials, it has outstanding dielectric, excellent tensile power and effortless to type at area temperature. They are often used for hair dryers, curlers, electric irons, motors and so on.
Shiny Mica Plate
YG-5660-G collection of Glossy Mica Plate are made from muscovite(or phlogopite) mica paper and substantial temperature resistant silicon resin, in contrast with rigid mica plate, its area are quite clean, but qualities have no diverse. YG-5660-G series has two species: shiny muscovite mica plate(YG -5660-G1) and glossy phologpite mica plate(YG-5660-G3).
Thick Mica Plate
YG-5660-T series of Thick Mica Plate is rigid mica plate with thickness in excess of 3mm, it is mica lamination developed for providing excellent resistant to substantial voltage and substantial temperature. YG-5660-T sequence has two species: thick muscovite mica sheet(YG-5660-T1) and thick phlogopite mica sheet(YG-5660-T3).
Thick mica plate is employed for cylindrical resistance heaters, thermal insulation in circuit breakers, chemical-engineering and electric powered appliances, electric powered sterilized cupboard, and in steel or metallurgy business for intermediate frequency furnace, arc furnace, and many others.
