Evonik Sipernat D13 is a hydrophobic precipitated silica imported from Germany. Designed for anti-caking, defoaming and silicone rubber reinforcement, it features excellent flowability and fast dispersion, suitable for various industrial formulations.
Strong hydrophobicity – not wettable by water, ideal for moisture-sensitive powders
High anti-caking effect – greatly improve flowability & storage stability
Fast defoaming – high efficiency, easy to disperse
Silicone rubber reinforcement – active filler for better mechanical properties
Uniform particle size – smooth processing, wide compatibility
Moisture-sensitive chemical powders – anti-caking & flow improvement
Defoamer formulations – industrial defoaming & fast bubble breaking
Silicone rubber (HTV/RTV/LSR) – active reinforcing filler
Fire extinguishing powders – anti-caking, flow aid & stable storage
Foundry masking powder, CPE & plastic powder additiv
