High‑end spherical silica powder for high‑speed CCL used to rely heavily on imports. Zhengrui’s R&D team with over 10‑year experience solves technical barriers including impurity removal, anti‑agglomeration and narrow particle‑size control.

Our CC, DB and FA‑series spherical silica powder features high sphericity and good dispersibility for high‑speed CCL, HDI, FCCL and ABF materials. Supported by national invention patents, our products match imported‑grade performance and advance domestic‑substitution progress.
