Polyurethane (PU) Polishing Pad for Wafer Surface

According to the different application fields of different polishing pads, optical products are divided into 4 categories:
♦ Ordinary optics, such as touch screen glass (including Windows glass, mobile phone glass, PAD, LCD glass can also fall into this category)
♦ Precision optics, all kinds of optical lenses, prisms, quartz glass, filters (blue glass), collimators
♦ Gallium arsenide, silicon carbide, sapphire substrate and epitaxial wafers, semiconductor wafers, and precision ceramics (zirconia ceramics, aluminum nitride ceramics)
♦ Infrared laser (such as this year's epidemic, the infrared industry is very hot, temperature control gun use is large)
