Product 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| ITEM | UNIT |
