Crystalline silica powder is an α-crystalline silica powder material manufactured from natural quartz through sorting, crushing, purification, grinding and classification processes.
It features high insulation, high voltage resistance and outstanding weather resistance. With a full range of particle size distributions, low dielectric constant and low dielectric loss, it can be matched with various surface modification formulas to fit multiple types of copper clad laminates.
