CLEAR-BLOC® 80 C

CLEAR-BLOC® 80C is a surface coated talc that are produced from high purity ore to provide high brightness, clarity, low iron content, for use as an anti-block additive in LDPE and LLDPE film applications where blocking, greater polymer stability with improved optical properties are required. CLEAR-BLOC® 80 and 100 talcs are platy, hydrophobic, non-abrasive, and chemically inert and are approved for food contact applications. CLEAR-BLOC talcs are produced with a priority process grinding system to improve consistency and uniformity of the material.
