Calcined Quartz Powder feature and excellent performance:
1), natural showed spherical range,  low absorption, high hardness, narrow particle size distribution, good fluidity.

2), high whiteness, low density,  bright white color. Use in coatings, paints, inks, plastic industry and other industries, to replace part of titanium dioxide, white carbon, reduce production costs.

3), anti-corrosion, scrub resistance, wear resistance, and does not contain organic matter, can enhance the UV resistance of the coating, and has good insulating properties.

4), excellent optical properties, refractive index (1.49N) close to the refractive index of the resin, such as PE, PP;  the crystal structure of the high-reflectance is helpful of light reflection, which may be substituted glass bead as filler of reflective paint can be enhanced skid resistance and The reflective paint.

5),  excellent thermal shock resistance, when quartz heated at 220-240 ℃, a certain degree of thermal expansion occurs, exactly compensate for the epoxy resin, plaster shrinkage during the curing reaction at this temperature, so that the casting body is not deformed. This feature is particularly suitable for epoxy resin casting materials, encapsulants and precision casting applications.
