In the field of industrial insulation materials, rigid mica sheets serve as the "armor" for equipment, protecting critical components in harsh operating environments. As a professional rigid mica sheet manufacturer, NBRAM Has provided key insulating materials for various high-temperature household appliances, industrial motors, industrial furnaces, etc. These machine operate at internal temperatures up to 600℃ while enduring continuous vibration. Our developed high-density rigid mica sheet, using premium muscovite raw materials combined with high-temperature resistant boric acid resin system, demonstrates exceptional insulation stability and mechanical strength in demanding marine environments. After five years of practical operation, this insulation system remains intact, a success that earned us high recognition in the marine electric propulsion field. Our Rigid Mica Sheet series includes Phlogopite Mica Plate, Muscovite Mica Plate, etc.
We have developed multiple series of rigid mica sheet products according to specific requirements of different industrial scenarios. For instance, in high-temperature kilns of the metallurgical industry, our reinforced rigid mica sheet, through added special fiberglass cloth, increases flexural strength to over 180MPa, effectively resisting deformation caused by thermal stress. For insulation needs in new energy vehicle battery modules, our ultra-flat rigid mica sheet achieves flatness of 0.02mm/m while possessing excellent thermal conductivity and electrical insulation strength. Particularly noteworthy is our arc-resistant rigid mica sheet developed for photovoltaic industry, maintaining structural integrity even under 1000℃ arc impact, whose exceptional ablation resistance provides reliable protection for equipment safety.
Currently, NBRAM rigid mica sheets have fully obtained UL94 V-0 flame resistance certification, UL certification (USA), and CE certification (EU). We maintain long-term cooperation with industry leaders like CRRC and Midea Group, with products widely used in industrial electric furnaces, new energy vehicles, photovoltaic equipment, and other fields, exporting to over forty countries and regions including Germany, Japan, and Brazil. Our introduced German intelligent press production line achieves precise layering and controlled curing of mica raw materials, with product density deviation controlled within ±2%. Each batch undergoes more than twenty rigorous tests including voltage withstand strength, thermal stability, and mechanical properties. Recently, our new generation environmentally friendly rigid mica sheet jointly developed with Shanghai Electrical Apparatus Research Institute, adopting water-based resin system, reduces VOC emissions to one-third of traditional products while increasing temperature resistance to 800℃. This breakthrough provides new solutions for green manufacturing. Choosing NBRAM rigid mica sheets means opting for quality commitment that stands the test of time.
If you're seeking reliable insulation solutions for high-temperature equipment, NBRAM's phlogopite mica plate series deserves serious consideration. This material maintains stable insulation performance even in continuous 900°C high-temperature environments, making it particularly suitable for metallurgical kilns, glass processing equipment, and aerospace thermal protection systems. Compared to ordinary muscovite, its heat resistance improves by over 30% with better thermal shock resistance. Customer feedback shows our phlogopite plates last 40% longer than similar products in aluminum electrolytic cell insulation layers. When procuring high-quality mica plates, we recommend choosing suppliers like NBRAM with complete quality control systems.
Let me tell you about the time we almost lost a whole production line because of inferior insulation - that's when I became a believer in Muscovite Mica Plates from NBRAM. These aren't your average mica sheets; the natural muscovite structure provides unmatched dielectric strength and thermal stability. I've seen them handle 1000°C+ in furnace applications without breaking down. If you're sourcing reliable insulation plates that won't let you down during critical operations, NBRAM's product should be your first choice.
