High Quality Muscovite Rigid Mica Sheet

Rigid mica board is a rigid board-like insulating material made of mica paper and high-performance silicone resin bonded and pressed at high temperature. Among them, the mica content is about 90%, and the silicone resin content is about 10%. Rigid mica board has the characteristics of high strength, good performance, less smoke and less odor. This series of mica boards are mainly used in household appliances (toasters, microwave ovens, air heaters, hair dryers, electric irons, etc.), metallurgy (such as power frequency furnaces, intermediate frequency furnaces, electric arc furnaces, etc.), medical equipment and other industries. heating brackets, pads, partitions.

Products Details

Product DisplayProduct DescriptionCompared with general insulating materials, the outstanding advantages of rigid mica boards are: Excellent high temperature resistance and insulation performance, the breakdown voltage still maintains 15kV/mm under the use environment of temperature 500-1000℃; Superior mechanical properties, with good flexural strength and hardness; Stable chemical properties, excellent acid and alkali resistance and aging resistance; Excellent environmental performance, does not contain toxic and harmful components, and does not produce toxic gases at high temperatures; Excellent processing performance, can be processed into various shapes without delamination. Packing: Generally 50kg is a pack, sealed with plastic film, and then packed in carton. When exporting, use fumigation-free trays and pack them according to less than 1000kg per tray, or use iron boxes for protection.Product Features
