We manufacture Ultra-High-Purity (UHP) PPB-grade Sodium Hydroxide (NaOH) specifically engineered for silicon and semiconductor etching applications, where absolute chemical purity is critical. Our manufacturing philosophy is built around contamination control at every stage—from raw material selection to final packaging.Production begins with carefully qualified, high-purity inputs and ultrapure water systems designed to eliminate ionic, metallic, and organic contaminants. 

The NaOH solution is then subjected to multiple stages of purification and polishing, using advanced separation and conditioning technologies to reduce trace metals and impurities to PPB levels. Throughout the process, all wetted parts, transfer systems, and storage environments are selected to be chemically inert and cleanroom compatible, ensuring purity is maintained without recontamination.
