Capacitor Chemicals

Capchem’s capacitor chemicals can be grouped under two main categories: capacitor grade chemicals for the preparation of aluminum electrolytic capacitors, including solvents, solutes and functional additives; and capacitor grade chemicals used to process high-purity aluminum into electrode foils and electronic aluminum foils for aluminum electrolytic capacitors, including solutes and functional additives, among others.

Benefiting from continuous investment in R&D and innovation, we have successfully developed a number of high-pressure solutes and functional additives with Capchem intellectual property rights, the performance of which surpasses that of similar products from Japan. Our customers include all the top 10 aluminum electrolytic capacitor manufacturers and aluminum foil factories in China, and we have more than 50% share of the capacitor chemicals market.

With the increasing popularity of digital Infrastructures, new energy vehicles and smart homes, there is a stronger need to improve reliability, extend service life and increase high temperature resistance of capacitor. Capchem is committed to the research of capacitor chemicals, making every effort to properly solve the main issues related to high pressure resistance, long service life and high temperature resistance of capacitors.
