Optical Coating Materials - SiO2 Particles

Professional research of the Company from 1990 production of coating materials - high-purity Si02 particles.
Equipment beyond the state-of-the-art technology, high purity, no acute angle.
The company produces quartz products scale:
(1) high purity quartz sand (≥ 99.998%) of 300 tons per month,
(2) high-purity Shi Yingying rod 30 tons per month,
(3) columnar-shaped quartz (SiO2) particles 20 tons per month.

The scale of today's domestic production of coating materials (SiO2) is the most complete, best quality, best price.
The company is one-stop production from quartz mine - high purity sand purification - drawn quartz rod - cutting columnar-shaped particles, the whole control of the quality of the product. Product quality in the leading position in China.
The company products are exported to the United States, Japan, South Korea, Taiwan, and well received by customers alike.
