As a leading mica sheet manufacturer and supplier in China, NBRAM has been dedicated to providing high-quality mica sheet products for global industrial customers for over two decades. In high-temperature operating environments such as power equipment, metallurgical casting, and new energy, traditional insulation materials often fail to withstand sustained high temperatures, while NBRAM mica sheets maintain excellent insulation performance. Our products have been widely used in Tesla's battery production lines, Siemens high-voltage switchgear, and China's high-speed rail traction systems, providing reliable high-temperature insulation solutions. Choosing NBRAM mica sheets means choosing a quality commitment that stands the test of time. Our Mica Sheet series includes Rigid Mica Sheet, Flexible Mica Sheet, etc.
Innovative Material Technology Breaking High-Temperature Limits
The exceptional performance of NBRAM mica sheets stems from continuous innovation in material formulation. We use natural white mica as the base material and employ a unique high-temperature calcination process that allows the mica sheets to maintain stable dielectric strength even at 1200°C. In an ultra-high voltage substation project, our reinforced mica sheets successfully replaced imported products, increasing transformer insulation life by 40%. For the new energy vehicle industry, we developed ultra-thin mica sheets (only 0.1mm thick) that solve the insulation challenges of space-constrained battery modules, with a thermal conductivity reaching 1.2W/m·K, far exceeding industry standards. In the photovoltaic inverter field, our arc-resistant mica sheets can withstand electric field strengths of 20kV/mm, providing solid protection for equipment safety.
Global Certification System and Customized Service Capabilities
NBRAM mica sheets have obtained UL94 V-0 certification, ISO9001 quality management system certification, and RoHS environmental testing, with products complying with the International Electrotechnical Commission's IEC 60371 standard. We have a complete experimental testing center capable of conducting over 20 professional tests including high temperature resistance, arc resistance, and bending strength. Currently, we maintain long-term cooperation with Fortune 500 companies including General Electric and Schneider Electric, exporting products to more than 30 countries and regions including Europe, America, Japan, and South Korea. Our engineering technical team provides customized services, completing samples in as fast as 3 days and achieving batch supply within 7 days. Last year, when a semiconductor enterprise built a new production line, we delivered special-sized mica sheets in just 5 days, ensuring the project's on-schedule operation. This rapid response and professional service capability make NBRAM a trusted partner for global customers.
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.
