Advanced Polyurethane Pads

MH polishing pads are uniquely designed for polishing and finishing a wide variety of surfaces where flatness and ultra-precision surface finish is critical. These materials include glass surfaces, ceramic components, precision lenses, semiconductor wafers and aluminum disks. An advanced polyurethane formula is the base of all MH polishing pads. This formula produces a microcellular pore matrix throughout the material and yields an extremely tough, durable surface to withstand the demands of finishing and polishing with abrasives. The MH structure provides maximum use of the abrasive by embedding it into the top surface of the pad to allow greater cutting action and minimizing free particles that can contribute to scratching. MH pads are available in different material densities with or without ceria abrasive fillers. Lower density materials have a more open pore structure. All MH pads are compatible with standard polishing slurries. This particular version is non-filled.

MHN15A039 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:

Berylium, Cadmium Zinc Telluride, Calcium Fluoride, Fused Silica, Lithium Niobate, Lithium Tantalate, Sapphire, Stainless Steel

Handling Instructions

Apply only to a clean, dry surface at room temperature. If an appropriate solvent, such as isopropyl alcohol, is used to clean the platen after a pad removal, allow the platen to dry completely and return to room temperature before applying a new pad. Solvents remaining on the platen or an unusually cold platen will lower PSA adhesion.

When applying the pad to the platen, peel the release liner from one edge of the pad. Fold liner back approximately 2 inches. Align the pad with the edge of the platen and adhere. In one continuous movement, slowly peel the remaining release liner off the pad while pressing the pad down on the platen. The application should be smooth and uniform with even pressure from the pad mounting tool (such as a flat disk or hand roller).

Do not try to reposition pads with PSA adhesive.

Storage

Product should be stored and transported in the original packaging. The product should be stored in temperatures between 10°C to 24°C (50°F to 75°F) and <50% humidity. Exposure for six (6) months or less to conditions between -17°C to 48°C (0°F and 120°F) and/or at relative humidity of up to 100% will not impact the product performance as long as the release liner remains intact and attached to the PSA. If the product is exposed to temperatures and humidity outside the recommended conditions, it may still be acceptable for use. In all cases, the product should be allowed to return to normal room temperatures prior to use.

Disposal

Dispose of in accordance with all applicable local regulations.
