Crystal Silica - Electronic Materials Grade:
Qmin-SIL Series crystal Silica is made of high purity natural quartz, by our unique technology as purifying, grinding, sieving/classfying, surface treating, drying, magnetic seperating, designed for EMC and other electrical application.
● High electric insulation property
● Particle shape good for flowability
● High chemical Resistance
● Pure(high SiO2 content, low Fe, Na, K & Al))
● Statistically controlled particle size distribution
● High whiteness
● High Hardness, good wearable
● EMC (Epoxy Molding Compound) Filler, coating powder
● Electrical Insulators
● Silicon rubber, paint etc.
