Soft Composite Silica Micro Powder supplied by Stanford Optics is made of natural quartz raw material through various processes, with excellent properties, and can be supplied in various specifications according to the needs, which is widely used in a variety of applications, such as material accessories, potting, and casting.
Soft Composite Silica Micro Powder, supplied by Stanford Optics , is made from high-grade natural quartz and several inorganic non-metallic minerals through a process of raw material compounding, ultra-fine grinding, precision grading, and surface treatment. The main feature of Soft Composite Silica Micro Powder is its low hardness, which significantly reduces the degree of abrasion on contact surfaces. In addition, it has stability and insulating properties, as well as good thermal properties and a low coefficient of thermal expansion, high whiteness, high transparency, and good interfacial compatibility with resins. This allows it to have a wide range of applications in the fields of surface coatings, composites, and specialty materials.
