Applications & Features

PR-01A Polyether Antifoaming Agent is formulated with fatty alcohol polyether as its main component. It maintains rapid defoaming and long-lasting foam suppression performance even in high-COD, highly polluted water, as well as strong acid and strong alkali environments. It is particularly suitable for various surfactant-based and high-polymer foaming systems. It contains no NP (nonylphenol) or APEO (alkylphenol ethoxylates), disperses easily in water, and meets environmental protection requirements. It is widely used in complex process environments such as environmental water treatment and paper machine white water circulation systems.

Product Specifications

Appearance: Colorless transparent to light yellow transparent liquid
pH (1% aqueous solution): Neutral (6.0 – 8.0)
Active Content: ≥99%
Viscosity (25°C): 300 – 500 mPa·s

Usage Instructions

This product is a high-concentration concentrate and should not be diluted with water. Dilution with water may cause product layering or emulsion breaking, significantly reducing defoaming performance and potentially increasing overall usage costs.

Recommended Dosage: It is recommended to adjust the dosage in 10 ppm increments at a location where the liquid disperses easily and flows well. Find the most economical dosage based on the viscosity, temperature, and agitation intensity of the foaming system.

FAQ

Q1: What are the cost advantages compared to traditional defoamers?

▶ The dosage is 40%–60% lower than traditional defoamers. This results in faster dewatering, lower energy consumption, fewer sheet breaks, and ultimately lower overall cost per ton of paper.

Q2: Does it affect sizing, dyeing, or finished paper quality?

▶ No, it does not. The product does not adsorb onto AKD/ASA sizing agents, dyes, or retention aids. It does not destabilize emulsions and does not affect Cobb values or paper strength.

Q3: Is it compatible with membrane filtration systems?

▶ Yes, it is compatible. Polyether defoamers are the preferred choice for landfill leachate treatment and seawater reverse osmosis membrane processes.
