Mica gasket
Mica gasket is cut or punched by mica paper or mica plate, mica board is bonded, heated and pressed by mica paper and silicone glue, of which the mica content is about 90%, and the silicone glue content is about 10%. Commonly used mica plates are divided into two types: muscovite plates and phlogopite plates, which have good electrical and mechanical properties, good heat resistance, chemical stability and corona resistance. Muscovite has better electrical properties than phlogopite, but phlogopite is soft and has better heat resistance than muscovite. Mica paper can also be combined with metal materials composite roll to make mica composite plate, mica composite version is a new excellent high-temperature sealing material, is constantly being developed and applied.
Classification and use
Heat-resistant mica soft board: Heat-resistant mica flexible board is a flexible plate-like insulation material made of special silicone resin adhesive powder mica paper and processed by baking and pressing. Uses: soft mica board has good softness, can be adjusted according to the requirements of the product at will, the long-term working temperature of muscovite soft board is 550 °C; The long-term operating temperature of phlogopite flex board is 850°C.
Heat-resistant mica hard board: Heat-resistant mica hard board is a rigid plate-like high-temperature insulation material made of high-quality mica raw materials and high-performance silicone resin by baking and pressing. Uses: heat-resistant mica hard plate thickness uniform, with good electrical properties and mechanical strength, the long-term working temperature of phlogopite hard plate is 850 °C, is a new type of electrothermal insulation material.
Performance characteristics
