The Secret of Silicone-Free Defoamers: How Chemi Tech Solves Industrial Foam Challenges

On modern chemical production lines, foam is often an "invisible enemy." It slows down operations, compromises product quality, and even poses safety risks. While silicone-based defoamers are widely used, their residual silicone can cause new challenges in high-precision applications. Chemi Tech, drawing on decades of expertise, has developed a high-performance silicone-free defoamer series, offering industries a purer, more reliable foam-control solution.

The Science Behind Foam

Foam forms when gas becomes trapped in liquid films. In industries like papermaking, coatings, and fermentation, agitation, heating, or chemical reactions accelerate foam generation. Uncontrolled foam leads to inaccurate filling, equipment idling, or even spill accidents. Traditionally, factories relied on silicone defoamers for quick suppression, but silicone’s persistence complicates post-process cleaning.

Chemi Tech’s Innovation

Chemi Tech’s R&D team analyzed molecular structures, testing hundreds of organic compounds to create a silicone-free system centered on polyethers and fatty alcohols. This formulation rapidly spreads across foam films, bursting bubbles by reducing surface tension—without silicone residue.

In a case study with a paper mill, silicone residues had caused "fish-eye" defects in finished products. After switching to Chemi Tech’s silicone-free defoamer, foam control efficiency improved by 20%, and silicone contamination vanished. "This isn’t just a new additive; it’s a process upgrade," remarked the mill’s technical lead.

Why Silicone-Free?

In Chemi Tech’s labs, every defoamer batch undergoes "extreme condition simulations"—from boiling dye vats to high-shear adhesive lines—ensuring immediate results. As engineers say: "We don’t sell cure-alls; we deliver scalpels."
