Capacitor Chemicals
As one of the four key materials of capacitors (anode, cathode, electrolytic paper, and electrolyte), the electrolyte acts as the actual cathode of the capacitor, bearing the critical responsibility of repairing the aluminum oxide film. It ensures the capacitor's high reliability, long lifespan, and other superior performance characteristics.
As a leading company in the field of capacitor chemicals, Capchem leverages cutting-edge technology and revolutionary product development to provide solutions for aluminum foil processing, aluminum electrolytic capacitors, solid-state capacitors, and more.
With the increasing adoption of digital infrastructure, new energy vehicles, and smart home technologies, the demand for capacitors with high reliability, long lifespan, and high-temperature resistance continues to grow. Facing challenges such as extended durability and heat resistance, Capchem is dedicated to advancing capacitor chemical research, focusing on solving critical issues like high voltage resistance, long lifespan, and high-temperature stability. To date, we have made significant breakthroughs in high-voltage resistance and longevity, with the goal of becoming the world's premier provider of capacitor chemical materials.
