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)

Thickness For Polyurethane Polishing Pad

Standard thickness for PU polishing pads ranges from 0.020 inches (0.508 mm) to 0.20 inch (5.08 mm)
