Application
These silicone-bonded rigid mica plates are designed for thermal and electrical insulation for various heating elements, household appliances, and other electrical components. They are offered in five different types to meet the individual requirements of users, providing outstanding electrical insulation at high temperature.
◇PB5662-1: A special low smoke and blister-free grade. It fully resists the extreme high temperature cycles typically encountered for example, in food grade toasters, micro-wave oven
◇PB5662-2: Standard grade for all heating elements of hair dryers, irons, heating oven, band heaters, nozzle heaters, etc.
◇PB5662-G, A higher density grade with smoother surfaces by steel pressing.. Most suitable for punching highly detailed pieces or when imprinting is required.
◇PJ5662-G: A special low smoke and blister-free grade. Softer and more heat resistant. For extreme high temperature application.
Availability
Sheet of 1000 X 600mm,1000 X 1200mm, 1000 X 2400mm.
Thickness 0.1-1.95mm.
Various strips and punched parts according to customers’ drawings and requirements.
Punchability
PB/J56 Series of rigid heater plates can be easily punched. Tools for punching difficult parts, however, should be provided with spring loaded hold-down plates.
