Suba™ 500 Perforated

Polyurethane Impregnated Polyster Felt Pad, Perforated

Suba polishing pads are polyurethane impregnated polyester felts. They are specifically designed for stock and intermediate polishing where achieving a high precision surface is critical. Suba pads should be used in combination with each other and with final polishing pads to produce a haze-free, low defect finish in dual or multi-step processes. Suba pads are ideal for a wide variety of materials including semiconductor wafers, glass, ceramics, specialmetals and plastic. Suba 500 is the industry standard for stock removal on silicon wafers. Suba 500 consistently provides rapid, efficient removal with good flatness results

Suba™ 500 Perforated Details

Base Material:

Felt

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.

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.
