Product introduction
Pamica 5161,5162 and 5160 series of silicone-bonded flexible mica plates/rolls are plate-shaped or roll-shaped electrical insulation materials made from exceptional high-grade Muscovite mica paper or Phlogopite mica paper, bonded with silicone.
They are designed for thermal and electrical insulation for heating equipment, are offered in six different types to meet the individual requirements of users in household electrical appliance industry and heavy industry.

| Type | Instructions |
|---|---|
| PB5161 | A very flexible texture muscovite grade mica sheet. It is used for normal thermal and electrical insulation for heating elements of electrical heating rods, micro electrical motors, microwave ovens. |
| PJ5161 | A very flexible texture phlogopite grade mica sheet. It is used for high-thermal and electrical insulation for heating elements of electrical heating rods, electrical soldering irons which has relatively small diameter. |
| PB5162 | A Semi-flexible texture & elasticity muscovite grade mica sheet. It is used for high-thermal and electrical insulation for heating elements such as hairdryers, space heaters, circuit breakers and transformers. |
| PJ5162 | A Semi-flexible texture & elasticity Phlogopite grade mica sheet, more extremely outstanding performance of high-thermal & voltage insulation. It is used as sheathing or covering, and also as a separator or insulation foil,a substitute for asbestos to be insulation pads of exhaust-pipes of cars. |
| PB5160 | A very flexible exture & elasticity muscovite grade mica roll. It is used for high-thermal and electrical insulation for heating elements of large-scare main frequency furnaces, middle frequency furnaces, low frequency furnaces, and electrical arc furnaces in heavy industries like steel industry and metallurgy industry. |
