Specialty Minerals Inc. (SMI), the industry pioneer in talc antiblocks, has now commercialized OPTIBLOC® clarity antiblock for film applications where optical properties are critically important. Film resins formulated with OPTIBLOC® clarity antiblock exhibit high film clarity, low haze, and low blocking force. OPTIBLOC® clarity antiblock also exhibits low interaction with stabilizers, slip agents, and processing aids, allowing formulation of film resins with good color, excellent stability, low coefficient of friction, and the lowest overall additive costs. OPTIBLOC® clarity antiblock's low abrasivity and ease of dispersion make it suitable for use via direct addition, as a masterbatch, or in non-dusting, 100% active concentrations.
