Foam in industrial processes can slow productivity, compromise quality, and drive up resource consumption. Evonik empowers formulators across industries to overcome these challenges with advanced silica and polybutadiene technologies engineered for superior foam control. Our innovative materials deliver the perfect balance of efficiency, sustainability, and formulation flexibility - ensuring smooth operations, cleaner processing, and reliable end‑product performance.
Why Evonik for Defoamers & Antifoams?
Silica engineered for performance: Hydrophobic SIPERNAT® and AEROSIL® grades significantly boost the defoaming power of oil‑based systems by enabling faster boundary‑layer penetration.
Powder‑ready solutions: ZEOFREE® and SIPERNAT® carrier silicas transform defoamer oils into easy‑to‑handle powders for dry blending applications.
High‑performance synthetic oils: POLYVEST® grades—including 130, 130 RFP, and eCO 130 Bio—serve as solvent‑free synthetic binders and modifiers in defoamer and deaeration systems. POLYVEST® 130 and POLYVEST® eCO 130 Bio are explicitly used in defoamers.
Sustainability built in: BIO‑based POLYVEST® eCO 130 Bio supports circularity via ISCC PLUS–certified mass balance concepts.
Trusted across industries: Effective in paints, coatings, paper, textiles, agriculture, water treatment, and more.
