About Sphelite

Sphelite, operated by ADVSORBENT Technology, was founded in 2017 by a PhD in materials science and is headquartered in Xunyang, Shaanxi Province, China. As a high-tech enterprise specializing in functional separation materials, we integrate R&D, production, sales, and engineering into a seamless technical service platform.

Recognized as a SRDI (Specialized-Refinement-Differential-Innovation) Small and Medium-sized Enterprise, we hold multiple core technologies and over ten invention patents. In 2018, we were certified as a high-tech enterprise and established a municipal R&D platform in Ankang City. By 2020, we launched an expert workstation for functional separation materials and achieved ISO9001:2015 certification. In 2022, we further strengthened our IP management with full system certification.

Our mission: "New Materials Make People's Life Better" — a commitment we pursue with relentless innovation.
