Product Description

Pamica rigid mica sheet for heater consist of approximately 90% muscovite or alternatively phlogopite, impregnated with high temperature resistant orgnic silicon resin. It is used as insulating parts for electric toasts, hair dryers, electric irons ,curlers, electric hot combs, strip heaters , baseboard heaters, also for gaskets, and in other appliances and applications where excellent resistance to moisture and thermal, mechanical and electrical properties are required. The products are certified by UL and in conformity with IEC371.
They are offered in five different types to meet the individual requirements of users, providing outstanding electrical insulation at high temperature.
1. PB5661: 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.
2. PB5662: Standard grade for all heating elements of hair dryers, irons, heating oven, band heaters, nozzle heaters, etc.
3. PB5662-G: A higher density grade with smoother surfaces by steel pressing. Most suitable for punching highly detailed pieces or when imprinting is required.
4. PJ5661: A special low smoke and blister-free grade. Softer and more heat resistant. For extreme high temperature application.
5. PJ5662: Standard grade for all heating elements operating in an extreme temperature range.
