Founded 2015
In the rapidly evolving landscape of new energy vehicles, rail transportation, and intelligent manufacturing, one challenge persisted: the lack of reliable, high-performance electrical and thermal insulation materials that could meet the stringent safety and durability requirements of modern industrial applications. Engineers and procurement professionals were forced to choose between expensive imported materials with long lead times or domestic alternatives with inconsistent quality and limited traceability.
That is why Ningbo Kaxite Sealing Materials Co., Ltd. was founded in 2015 in Ningbo, Zhejiang Province — one of China's most advanced industrial and manufacturing hubs. Our mission was simple: to develop and manufacture mica-based insulation materials that match or exceed international standards, while offering factory-direct pricing, full batch traceability, and responsive technical support. Today, we are proud to be a trusted insulation partner for manufacturers across new energy vehicles, rail transit, aerospace, military shipbuilding, and smart home appliance industries in over 60 countries.
Our product portfolio encompasses mica rigid materials, flexible mica sheets, mica heating elements, thermal management mica safety components, mica tapes, mica plates, mica tubes, mica rolls, mica paper, and epoxy glass laminates. These materials are engineered to deliver exceptional electrical insulation, thermal resistance (up to 1000°C), and mechanical strength.
Beyond manufacturing individual products, we provide comprehensive one-stop system solutions for electrical and thermal insulation — reducing design complexity, shortening development cycles, and ensuring seamless integration into final products.
Unlike trading companies, we own and operate our entire production facility in Zhenhai District, Ningbo. Our workshop is equipped with advanced mica paper manufacturing lines, high-temperature lamination presses, precision cutting systems, and a fully equipped QC laboratory. Every batch undergoes rigorous testing — including dielectric strength verification, thermal aging assessment, flame retardancy testing, and dimensional precision inspection — ensuring full compliance with international standards.
🏆 Recognized as a "Small-sized Giant Enterprise" featuring specialization, precision, technology, and innovation, as well as an "Invisible Champion" enterprise in Zhejiang Province.
