TFT-LCD Glass thinning

 Polishing powder is suitable for TFT LCD glass thinning process. It has the characteristics of fast cutting force and high product yield.

(1) The brownish red polishing powder is prepared by fluorination roasting with rare earth carbonate as raw material, which can be used for cover glass processing.
(2) Average particle size 1.4-1.8 μ m. The maximum particle size is less than 8 μ m. It can meet the accuracy requirements of cover glass.
(3) Fast polishing speed and good particle wear resistance; Good suspension and easy to clean.
