Evonik solutions for processing plastic powders, granules and pellets
- Free flow aid
- Anti-caking agent
- Anti-static effect
Evonik’s silica and metal oxides improve storage, handling and processability of plastic powders, granules and pellets which are the starting material for countless everyday products and high-tech components. Polymers and elastomers often have a low glass transition temperature and therefore tend to cake. Flowable plastic particles, however, are crucial for efficient thermoplastics processing such as compounding, extrusion, injection molding and sintering. SIPERNAT® specialty silica, AEROSIL® fumed silica and AEROXIDE® fumed metal oxides are efficient flow- and anticaking aids, prevent caking and keep plastic powders or granules free-flowing, even after long term storage at elevated temperatures. In addition, they are able to reduce electrostatic charging.
