What is the difference between GPO-3 laminates and GPO-3 grinding plates?

GPO-3 laminated board is a hard board like insulation material made by hot-pressing an alkali free glass fiber felt soaked in unsaturated polyester resin paste and adding corresponding additives. The grinding plate is a thickness precision machined product based on the laminated plate, and the thickness tolerance is more accurate than that of the laminated plate.
