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.

YJ-712 D (White): YJ-712 D is a high-quality polishing powder widely used for traditional low-speed polishing and manual reworking of repair parts; it can also be used with polyurethane for high-speed polishing. Its particles are fine and uniform, and it provides high surface precision after polishing, long service life, low grinding heat, and little tendency to leave marks or other defects on the processed surface. It is cost effective and suitable for final polishing of high-precision parts with surface roughness below 1 micrometer or of soft-material surfaces.
