1250 Mesh Silica Powder (particle size approximately 8-10 microns) is approaching the threshold of the micron level, and its production falls within the realm of high technology. Stable mass production of such a fine and concentrated distribution product requires grinding combined with strict classification technology.
This specification of silica powder possesses a series of outstanding properties. Due to its extremely fine particle size, it occupies a higher packing volume fraction in composite systems, more effectively improving the physical properties of the material. For example, in epoxy potting compounds, the addition of 1250 Mesh Silica Powder can reduce the CTE of the cured product even further, achieving a perfect match with adjacent materials and greatly reducing the risk of thermal stress cracking, which is crucial for the reliability of power devices and automotive electronics. Simultaneously, the fine particles help form more uniform thermal conduction paths, improving overall thermal conductivity efficiency. In the manufacturing of copper-clad laminates (CCL) used for high-frequency, high-speed printed circuit boards (PCBs), 1250 Mesh Silica Powder can further optimize dielectric properties to meet the requirements of next-generation communication technologies. In the field of advanced ceramics, such as alumina and silicon nitride ceramics, it serves as an active sintering additive, lowering the sintering temperature, promoting grain refinement, and obtaining high-density, high-strength performance ceramic components. Additionally, in the cosmetics industry, strictly inspected and surface-treated 1250 Mesh Silica Powder can be used as a raw material for products like baby powder and foundation, providing a silky skin feel and adsorbency. Its low abrasiveness also makes it suitable for polishing agents in precision instruments. The application of 1250 Mesh Silica Powder fully demonstrates the performance leap brought about by material fineness.
