Remark:Customizations are available upon requests.    


Features
1. High removal rate, by using big size of silica particle, you can achieve fast finishing;
2. Different particle size could be made to your request;
3. High purity can diminish impurity on electrical products;
4. High smooth processing, SiO2 particles won't cause damage on physical devices.


Application

Fiber optic connectors final finish.
