Light powder particle base material refers to the fine, pulp-free melamine-formaldehyde resin powder used as the base material for glazing. In the melamine tableware industry, this material is known as glazing powder or “jing fen” (精粉), produced by reacting formaldehyde with melamine, drying the resin, and ball-milling it into a white powder without cellulose pulp . It is sprinkled onto tableware surfaces before final pressing to form a transparent, glossy protective layer. Grades such as LG220 are used for A5-grade melamine ware, while LG110 serves A1/A3 materials and LG250 is for decal application
