Product DescriptionProduct DetailsAccording to customer needs, the voltage capability can also be increased to 1-2 times the conventional standard value. Full-flex and semi-flex boards can be customized according to the required toughness. This series of mica boards can be used in hot air guns, induction furnaces, motors, transformers, etc., as cover sheets, separators, insulating sheets or high temperature resistant sealing materials for the above electrical appliances.Product FeaturesCompared with general insulating materials, the outstanding advantages of Flexible 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, Flexible mica board has good tensile properties; 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.| ITEM | UNIT |
