Polyether defoamers are high-efficiency, non-silicone agents crucial for the paper industry, offering rapid bubble breaking, long-lasting foam suppression, and excellent thermal stability (

is less than 150 raised to the composed with power C

) in high-temperature, alkaline systems. They are used in pulp washing, black liquor treatment, and coating applications to prevent defects like pinholes while maintaining system cleanliness.

Key Features & Advantages in Paper Industry

Superior Performance: High-efficiency, non-silicone, and non-toxic formulas that provide rapid foam knockdown and lasting suppression.
High Temperature/Alkali Stability: These defoamers are stable in environments up to
$150 raised to the composed with power C$
and across pH 3-14, making them ideal for Kraft pulp brown stock washing.
Surface Quality: They prevent coating defects (pinholes, fish eyes) and improve paper smoothness and glossiness, especially in coatings.
Versatility: They disperse well in white water and are suitable for diverse applications, including toilet paper production, wastewater treatment, and coating preparation.
No Silicone Contamination: Ideal for applications where silicone-based products are forbidden, such as during coating and printing.
