The STEP-PLUS pad is made from woven cellulose acetate filaments, which allow the yarns to resemble those of silk. While they have good elasticity, they are not very hydrophilic and the fiber is not very absorbent. As a result, the pad holds different types of suspension and diamond on the surface. The yarns are also highly resistant to abrasion. This pad is universal. After a lapping phase, it can be used in 99% of polishing applications (hard ceramics to yellow gold). Reserved for small grain sizes from 6 μm to 0,1 μm, it achieves a good removal rate, while maintaining sharp edges.
