Freeman Series- Understanding the Cohesive Nature of Powders through Shear Cell Analysis

Worldwide

Agriculture granules, food powders, compact powder cosmetics, powder and unit-dose detergents are complex combinations of both powder and liquid ingredients which must remain clump-free in production and finished packaging. Shear-Cell testing on the FT4 Powder Rheometer® offers predictive insight into the cohesive nature of powders in bulk-storage and packaging conditions. This talk will cover the evaluation of powder cohesivity and the use of Evonik’s SIPERNAT® and ZEOFREE® processing aids to alleviate these challenges.

Freeman Series- Importance of Pre-Consolidation Stress Conditions for Optimized Shear Cell Tests

Worldwide

Agriculture granules, food powders, compact powder cosmetics, powder and unit-dose detergents are exposed to a variety of stresses during conveying, storage, and placement into final packaging. Shear-Cell testing on the FT4 Powder Rheometer® helps to predict changes in cohesivity based on external compression and consolidating forces seen in manufacturing. This talk will cover the evaluation of powder cohesivity under different pre-consolidating stresses and the important role of Evonik’s SIPERNAT® and ZEOFREE® processing aids.

Evonik Silica for Anti-block Applications

Antiblobk

North America & LATAM

Evonik’s vast range of silica, silicates, and alumina can be used for several effects in a wide variety of industries. One of those effects is anti-blocking agents for polymer films. These materials can be used to provide the necessary spacing to achieve film separation while maintaining high clarity.  In this talk, the product most recently developed for this effect will be discussed, SPHERILEX®.  SPHERILEX® products are generated via a patented production process yielding unique spherical particles ideal for effective anti-blocking, easy processing, and high clarity within different polymer systems.

Freeman Series- The Application of Powder Characterization Techniques in Personal Care Using the FT4 Powder Rheometer®

Worldwide

The FT4 Powder Rheometer® has various testing methods that apply directly to the manufacturer and consumer experience. As we observe a rise in sustainability efforts, there is greater need for solid or powdered personal care and cosmetic formulations. In this talk, Evonik's precipitated silica grades, SIPERNAT® and SPHERILEX® , will be evaluated in personal care formulations for their improved cohesion, stability, and flow properties in the presence of starch, talc, and other common fillers.
