Flash Surface Technologies---PU Polishing Pads

We provide twelve Cast Polyurethane (PU) Polishing Pads. Abrasive fillers include ceria and zirconia, some pads do not have abrasive filler. Those polishing pads can be used in the polishing and finishing of glass, LCD/LED substrates, precision optics, hard disk, metal and semiconductor wafer surfaces.

SIZE

FST PU Polishing Pads are available in full sheets or cut to size. Standard dimensions include 23 x 55 inches (584.2 x 1397mm), 36x71 inches (914x1803mm), 42x42 inches (1066x1066mm), 52x52 inches (1320x1320mm), Φ26 inches (660mm), Φ32 inches (812mm), Φ38 inches (965mm), Φ52 inches (1320mm). Custom sizes, shapes and configurations are available.

THICKNESS

Standard thickness for FST PU Polishing Pads ranges from 0.020 inch (0.508mm) to 0.20 inch (5.08mm).

PSA BACKING

Pressure-Sensitive Adhesive (PSA) backing is available on all types of FST pads. PSA backing ranges from high-holding to low tack and easy release.

GROOVING

Grooves improve pad performance by reducing excess slurry from the pad surfaces. The depth of a groove is usually half of the pad thickness, only pad with thickness of more than 2 mm can be grooved. Groove width is usually 2mm, and the island size is usually 16 x 16 mm. Our pad is offered in a variety of groove configurations.
