| titleOfInvention | Polyurethane installation pad |
| abstract | The present invention relates to a kind of polyurethane supporting pads, wherein low P compression ratios are 1 to 10%, the low P compression ratios are the ratio between difference and first thickness of first thickness and second thickness, and first thickness to the thickness direction of installation pad by applying 5g/cm 2 Pressure and measure, and second thickness pass through to installation pad thickness direction apply 100g/cm 2 Pressure and measure, and wherein low P reduction lengths --- it is the difference of first thickness and second thickness --- are 15 to 100 μm.According to the present invention, it is possible to provide a kind of polyurethane installation pad has high compression rate and excellent elasticity under practical polishing condition, and may be implemented evenly and efficient polishing, to reduce polishing defect rate. |
