Company Profile

Dongguan SAT Nano Technology Material Co., Ltd. is based in Dongguan, Guangdong Province — one of China's most active manufacturing and innovation hubs. Founded in 2015, we operate 100tons per year and serve customers across 30 countries.

Our core product lines include metal powders, carbide powders, oxide powders, and MXene materials, along with other chemical reagents. These advanced materials serve a wide range of applications, including chemistry and chemical processing, pharmaceuticals, life sciences, optoelectronic displays and lighting, environmental protection, new energy, catalysis, and wear-resistant applications.

Our customers are primarily universities and research institutes, who use our materials for laboratory R&D; we also supply industrial customers for production. To support both, we provide analytical and testing services — particle size distribution, purity and elemental analysis, and electron microscopy (SEM / TEM) — so customers can verify the specification of the material they receive. Selected products are supported by SGS and RoHS reports, COA, SEM images, XRD patterns, MSDS/SDS, and ISO 9001 certification.
