DEFOAMER AND ANTIFOAMERS

Defoamers and Antifoamers – Effective Foam Control for Paper Manufacturing

Thermax offers a comprehensive range of defoamers and antifoaming agents designed to manage and eliminate foam in paper manufacturing systems. Foam can cause severe process disruptions, affecting productivity, sheet formation, and final product quality. Our solutions are engineered to work both preventively (antifoam) and correctively (defoamer)—providing dual-action performance.

Why Foam Control is Critical in Papermaking

• Reduced drainage and formation issues
• Air entrainment and sheet defects
• Inconsistent coating applications
• Operational slowdowns and increased chemical usage

Thermax Defoamer Solutions

• Prevent foam formation at its source
• Collapse existing foam quickly and efficiently
• Remain effective under high shear and temperature conditions
• Work across a wide pH range and furnish types

Key Benefits

• Dual-function action: Prevents and eliminates foam
• Enhanced drainage and retention in paper machines
• Improved paper surface quality and uniformity
• Increased machine speed and operational efficiency
• Suitable for various stages including wet-end and coating processes

Applications

• Paper machine wet-end
• Coating color kitchen
• Stock preparation systems
• Wastewater treatment sections

There is an extremely diverse set of chemical formulations, which can be effective either to prevent foam (anti-foam) or to destroy it, once it is formed (defoamer). Most foam-fighting chemicals can serve either role. Thermax defoamers act as a dual effective agent for efficient foam control in paper manufacturing systems. Certain grades of defoamers are also used in the coating colour kitchen.
