THE CHALLENGE: Plastics manufacturers must deliver high-performance products with regulatory compliance, while ensuring production efficiency, product stability, and consistent quality. Common challenges in plastics processing are poor powder flow, caking during storage, clogged dosing systems as well as blocking of films.
THE SOLUTION: Evonik's high-performance silica, silicate, and fumed alumina products provide the plastics industry with tailored solutions for better processability, higher throughput, and improved material performance. They serve as anticaking agents and free-flow aids, and they provide antistatic and antiblocking effects.
Hydrophobic and hydrophilic precipitated and fumed silicas enhance the processing of different types of plastic powders and granules, for example, superabsorbent polymers, TPEs, and many others.
AEROSIL® fumed silica enhances milling efficiency, lowers caking tendency, and improves flowability and dosing precision of polymer powders.
Polymer granules are prone to electrostatic charging. AEROXIDE® fumed alumina provides an antistatic effect by neutralizing the charge, ensuring uninterrupted flow.
Special silica products such as SPHERILEX® 30 AB or SPHERILEX® 60 AB prevent the blocking of polymer films. This is crucial for film production, winding, refining, tailoring, storage, and handling of films in their final applications.
THE SMART EFFECT: Evonik’s silica offers significant benefits beyond technical functionality by unlocking efficiency and sustainability throughout the value chain. Integrating our silica into production processes enables customers to move faster, cleaner, and smarter from formulation to final application.
Our solutions help reduce downtime during production and processing. They enhance product quality and extend shelf life. Overall, silica contributes to more sustainable plastics production with less waste.
