SPHERILEX® 30 AB is a specialty precipitated silica, which has attractive properties for antiblocking application of polymer films. As shown in antiblocking testing, its spherical particle morphology and uniform particle size distribution  provides optimal clarity and antiblocking efficiency in plastic films. Based on its low absorptivity it performs also excellent in combination with slip agents. High masterbatch loadings are possible due to its easy incorporation and dispersion during thermoplastic compounding process.


SPHERILEX® 30 AB is used as antiblocking agent in PE, PP, PET and PA film grades. It is especially designed for thin films and biaxially oriented film applications. Main benefits are: Low Coefficient of Friction (CoF) Outstanding transparency of films Low absorption of other polymer additives Excellent dispersibility and high masterbatch loading Low abrasion of processing equipment
