YJ-7 Series Polishing Powder YJ-705?? (White)
YJ-7 series cerium oxide polishing powders are used for cold processing in optics, optoelectronics, precision instruments, scientific research, defense, and other industries. They offer uniform particles, good suspension and dispersion, no adhesion, easy cleaning, broad applicability, good surface quality after lens processing, and good cost effectiveness. They can be used for single-stage or final polishing of lenses with medium- to high-precision requirements, for different soft materials such as F, ZF, and LaF.LaK series glasses, and for different processing methods. They are commonly used for lenses, prisms, glass substrates for flat liquid-crystal panels, optical discs, crystal components, and similar items. Polishing-powder concentration: approximately 40-100 grams/liter; excessively high concentrations are not recommended. Polishing temperature: around 30℃. Polishing-pad materials: compatible with various polishing-tool materials, including polyurethane pads, black polishing pads, pitch, felt, and synthetic leather. Packaging: 20KG/carton, with an inner plastic bag.
