Why Flock Makes a Great Polishing Surface

Engineered Flocked Polishing Pad Material

In many industries, polishing of materials or products to achieve final specifications is important. Customers must know they can rely on suppliers to achieve the agreed upon specifications.

One example is to planarize a surface, but how do they do it? The answer is with engineered flocked consumable polishing pads. Available in self-adhesive or plain pads, they come in all different sizes and durabilities, depending upon the polishing needs. Flock fiber is a great carrier of polishing materials like aluminum oxide or various micron sized diamond polishing compounds. The rayon fiber swells with aqueous slurry and holds the grinding media during the polishing process. The result is very fine polish.

Most pads are produced by applying a rayon flock of various lengths onto a fabric, nonwoven, film, foam, or other sustrate which is suitable for most final polishing needs. The flocked fiber and backing can be selected for its chemical resistance properties. Applying the flock fiber in different densities allows the pad to resist wear over time and reduces contamination of the polishing compound slurry. Air embossed pockets for holding polishing slurry can also be added.

Flocked polishing pads are particularly useful for the planarization of semiconductor wafers. Such planarization is carried out using a polishing fluid, such as a slurry. During polishing, the polishing fluid is placed between the flocked polishing pad surface and the substrate, such as a semiconductor wafer. As the pad is moved relative to the substrate being polished, the substrate is planarized. Improved flow of polishing fluid generally allows for more efficient and effective polishing performance.

We can supply product in roll-to-roll widths up to 64". The flock fibers can be rayon, nylon, polyester, cotton, or blends flocked on fabrics, nonwovens, films, foams, or other substrates. Polishing materials can be custom designed for your requirements with different diameters, lengths, lusters, and cross sections of flock fiber. We only use water based non toxic adhesives for the flocking process.

For over 45 years, we have been a leading supplier of flocked consumable polishing pad materials for the optical, electronic, metal, fiber optic cable, semiconductor wafer, and other markets.

Our team at Spectro Coating Corp. is ready to work with you to develop the perfect flocked polishing product to meet your requirements.
