Polyether Defoamer | Silicon-Free Industrial Defoamer Food & Medical Grade Polyether Antifoam Agent

Product Overview

Polyether defoamer and industrial antifoam agent are high-performance silicon-free industrial defoaming and foam suppression materials. They are refined through polycondensation reaction using fatty alcohol and polyhydric fatty alcohol as main raw materials with propylene oxide and ethylene oxide. The product contains no silicon and causes no silicon pollution risks, effectively avoiding silicon spots, silicon residues, membrane blockage, coating defects and other problems caused by silicone defoamers. It is a preferred industrial defoamer product for working conditions that prohibit silicon pollution.

This product features reliable instant defoaming and long-term foam suppression performance, with good water solubility and fast dispersion speed. It has excellent compatibility with various systems and will not affect the transparency, viscosity, film-forming property and subsequent processing performance of the original system. As a versatile industrial defoamer, it is widely applicable to various industrial foaming systems including phosphate ore processing, surface treatment, membrane filtration, papermaking, coating, sewage treatment and sugar making, solving various industrial foam problems stably.

To meet special industrial demands, our company provides supporting food and medical grade polyether defoamers and industrial antifoam agents. Made of refined food-grade raw materials, the products are available in two types: modified silicone emulsion type and food-grade compound polyether type. With reliable safety and compliance, they can be widely used in high-standard clean production scenarios such as food processing and pharmaceutical production, serving as compliant food-grade and medical-grade defoamer products.

Core Advantages

• Silicon-Free & Pollution-Free, Suitable for High-End Working Conditions: Adopting pure polyether synthetic formula without silicone ingredients, it leaves no silicon residue or silicon pollution. It prevents membrane blockage, coating shrinkage cavities and product spots, customized for silicon-free production scenarios.
• Dual Functions of Defoaming and Foam Suppression: This silicon-free defoamer achieves rapid foam breaking and long-term foam inhibition. It can eliminate floating foam in the system and delay foam regeneration, stabilizing liquid level foam status and improving production continuity.
• Good System Compatibility: Featuring low viscosity and excellent dispersibility, it can be evenly mixed with various water-based industrial systems without delamination or oil floating, and will not affect product transparency and subsequent processing effects.
• Low Dosage & Cost-Effective: Adopting high-efficiency active formula, the recommended dosage for conventional systems is only 0.2-1.5‰. A small dosage can deliver stable defoaming effects, effectively reducing production material costs.
• Dual Specifications for Industrial & Food/Medical Use: Covering industrial-grade defoamer and food & medical-grade defoamer series, it adapts to ordinary industrial production and high-safety production scenarios of food and pharmaceutical industries, covering diverse defoaming application needs.

Usage Method

This polyether defoamer and industrial antifoam agent features flexible usage and adaptable to on-site processes. It can be added directly or diluted with water in advance, suitable for various industrial defoaming and foam suppression operations.

1. Direct Addition: It can be quantitatively added directly to the foaming system without dilution if the system has sufficient stirring and good fluidity, achieving rapid effect.

2. Diluted Addition: For fine production systems, pre-dilution with clean water is recommended for uniform dispersion, avoiding performance impact caused by local high concentration.

3. Recommended Dosage: The conventional recommended dosage for industrial systems is 0.2-1.5‰. The optimal dosage shall be determined through on-site tests according to foam volume, water hardness, temperature and actual working conditions.

4. Addition Timing: It can be added after foam generation to eliminate existing foam, or added in advance as a foam inhibitor to prevent foam formation from the source and ensure stable production.

FAQ

Q1: What is the difference between polyether defoamer and silicone defoamer?

As a popular silicon-free defoaming system, polyether defoamer features no silicon pollution and no silicon residue. It will not block membrane equipment or cause coating defects, suitable for precision industrial working conditions. Silicone defoamer has fast defoaming speed but may cause silicon pollution, which is not applicable for silicon-free scenarios.

Q2: Can food-grade polyether defoamer be used directly in food processing?

Yes. Our food and medical-grade polyether defoamer is made of qualified food-grade raw materials, which can be compliantly applied to food processing, pharmaceutical production, biological fermentation and other scenarios.

Q3: Does polyether defoamer need dilution before use?

Dilution is not mandatory. It can be added directly with good system stirring conditions. Pre-dilution is recommended for fine processes to achieve more uniform dispersion.

Q4: Will low dosage lead to poor defoaming effect?

This industrial defoamer contains sufficient active ingredients. A low dosage of 0.2-1.5‰ can achieve reliable defoaming and foam suppression effects. The dosage can be adjusted according to on-site foam concentration and confirmed by small tests for better cost performance.

Q5: Is it suitable for membrane filtration systems?

It has good adaptability for membrane filtration systems. The silicon-free formula is not easy to block membrane pores or pollute membrane components, serving as a reliable defoamer product for ultrafiltration and microfiltration systems.
