Slip Antiblock Masterbatches Thermoformed items and plastic sheets need slip antiblock additives to avoid undesirable adhesion. Masterset slip/antiblock masterbatches reduce adhesion and the coefficient of friction together, deep drawing is carried out cleanly and smoothly. The undesirable adhesion of extruded foil during rolling and unrolling is minimized and deep drawn items are easily denested without scuffing or damage to their outer surface.
