AI Overview
Polyether antifoams are highly effective, non-silicone agents used in paper sizing (AKD/rosin) to eliminate surface foam and white water entrained air, enhancing paper quality and machine speed. These, such as BLU IJA or SY-9133, are typically modified polyethers, branched alkyl polyethers, or polyether esters that offer high temperature and alkaline stability. They are ideal for high-shear environments, offering quick foam knockdown and preventing pinholes with a recommended dosage of 0.1-0.5 kg per ton of paper.

What is the main ingredient in defoamer?
Silicone-based defoamers are polymers with silicon backbones. These might be delivered as an oil or a water-based emulsion. The silicone compound consists of a hydrophobic silica dispersed in a silicone oil. Emulsifiers are added to ensure that the silicone spreads fast and well in the foaming medium.
