Soft composite silica powder

Soft composite silicon powder is a kind of natural quartz and other inorganic non-metallic minerals as raw materials, through various processes such as compounding, melting, cooling, crushing, ultra-fine grinding, precision grading, surface treatment, etc

【Product Series】:

YS-FR YS-HFR YS-ZF YS-HZF
  • Feature:

    Compared to crystalline silicon powder, it has lower hardness and less wear on equipment; Low coefficient of thermal expansion; Having a stable chemical composition ensures excellent chemical stability.

  • Application:

    Applied in industries such as Copper-clad laminate, Ink coatings, Adhesives, Electronic packaging, and Composite materials.
