SHANGHAI GUANGHE OPTICS MANUFACTURE CO.,LTD.

High precision rare earth polishing powder

Sales specification：0.8μm / 1.2μm / 1.8μm / 2.6um.

APPlications：Lak, LaF series of soft optical glass materials with high-precision polishing, coated glass substrates, high-precision optical components, window sheets, chips, and watch doors.

Profuct Features：

1. Polishing materials are made from different amounts of rare earth materials by means of fluoridation and calcinations.The hardness of polishing materials is fifferent because of different rae materials, so they are suitable for different applied materials.

2. The average grading of polishing materials is 0.6 to 3.0,the largest particle is lesser than 9,so precision products could be obtained by using poloshing materials.

3. The particles of poloshing mateials are wear-resisting,of good suspension property and easy to clean.
