SPHERILEX® DP-0121 Silicon Dioxides have attractive properties for polymer film antiblock applications. As shown in antiblock testing, SPHERILEX® Silicon Dioxide particle size and uniform particle size distribution provides optimal clarity and antiblock efficiency in plastic films. Higher masterbatch loadings are possible due to its low oil absorption, which also prevents absorption of slip agents. The spherical morphology results in reduced equipment abrasion and the composition allows for a tailorable refractive index of 1.44 to 1.51 for improved clarity in a variety of films. 


Low oil absorption for high masterbatch loadings High optical clarity with tailorable refractive index Low abrasion on masterbatch extruding equipment
