EXTERION™
Urethane polishing pad
EXTERION™ pads are made of an advanced urethane with ceria filler, specifically formulated to meet the needs of different glass and optical polishing applications. The unique and controlled pore structure differenciate them from competitor pads in both performance and pad wear/lifetime. EXTERION™ pads provide significant advantages in achieving consistent, reproducible polishing results.
Details
Base Material Urethane
Shelf Life 12 months
Packaging Pads are packaged face-to-face (polish side to polish side) and sealed inside a plastic bag to ensure cleanliness during transportation. The bags are taped to the side of the box to prevent the bag from slipping and damaging the pads. Pads should always remain flat. Bending pads during handling can cause wrinkles in the PSA and premature delamination of the release liner.
Applications Acryllic, aluminosilicate, APEX, BK7, BK9, borofloat, borosilicate, ceramic, crystal, quartz, glass, gorrilla, leaded crystal, phosphate, pyrex, SF6 flint, soda lime - float, zinc borosilicate
- EXTERION™ C74A has a lower density and pore count to improve the scratch rate and surface quality.
- EXTERION™ C76C has a higher density and pore count, which results in higher removal rates.
