New Generation Antiblocking Additives

SPHERILEX® represents the latest technological advancement from EVOINK in antiblocking technology for polymer films. These silica particles are produced in a state-of-the-art process which gives rise to narrow particle size distributions and spherical morphologies. As a result, Coefficient of Friction (CoF) and haze are both reduced in a highly efficient manner. Low absorption capacities mean less water to vent and a reduction in the absorption of other polymer additives. Spherical morphologies ensure lower wear on equipment, good dispersibility and higher masterbatch loadings. Get in touch with the technical sales team at Lawrence Industries to see how these new antiblocking particles could give your masterbatch the cutting edge.


    • Precipitated silica with tight particle size distribution and spherical morphology.

    • Lower than usual absorption capacity.

    • Particle size (d50) of either 4.0 or 5.7 microns, depending on the grade.


    • Highly efficient i.e. low dosages allow for optimal clarity and cost engineering.

    • Very effective at reducing Coefficient of Friction (CoF).

    • Low absorption ensures minimal interference with other additives and excellent combination with slip additives.

    • Less need for extruder venting due to low water content.

    • High masterbatch loadings possible due to easy incorporation.

    • Low wear on equipment due to the spherical particle morphology.

Typical Applications

    • Antiblocking agent for polymer films: polyolefins, polyesters, polyamides and biaxially oriented films.
