Soft Composite Silica Micro Powder Description
Soft Composite Silica Micro Powder, supplied by Stanford Advanced Materials (SAM), 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.

Soft Composite Silica Micro Powder Applications
1. Coatings and plastics: Soft Composite Silica Micro Powder can be used as additives in coatings and plastics to improve their hardness, abrasion resistance, corrosion resistance, and aging resistance. They can also be used to enhance the mechanical properties and tensile resistance of materials.
2. Rubber products: Soft Composite Silica Micro Powder can be used as filler in rubber products to improve the strength, abrasion resistance, and aging resistance of rubber products, such as rubber seals, rubber pipe fittings, rubber seals, and so on.
3. Electronic materials: Soft Composite Silica Micro Powder can be used to prepare electronic materials, such as conductive materials, insulating materials, and packaging materials. They can provide excellent insulating properties, high-temperature resistance, and chemical stability.
4. Lubricants: Soft Composite Silica Micro Powder can be used as additives for lubricants to reduce friction and wear, and improve the wear resistance and service life of mechanical parts.
