100% Solid Content Polyether Ester Defoamer LY-XP206 for Broad Industrial Applications

LY-XP206 is a premium-grade, 100% active solid content polyether ester defoamer synthesized with an advanced matrix of high-purity polyether esters, active dispersants, and stabilizing agents. Engineered specifically to combat severe foam issues in water-based chemical processes, it delivers an exceptional dual-action profile of immediate foam knockdown and long-lasting foam inhibition.

Unlike conventional emulsions that face destabilization under complex chemical environments, LY-XP206 disperses readily and completely in cold water systems. It provides modern automated processing lines with an ultra-concentrated, highly efficient foam control agent that minimizes chemical additive volume while maintaining absolute process continuity.

Core Technical Advantages & Value Proposition

1. Dual-Action Performance (Immediate Knockdown & Long-Term Inhibition)

LY-XP206 features outstanding versatility in foam management. It can be introduced as a rapid knockdown agent to break down large volumes of existing surface macro-foam. Alternatively, it can be integrated directly into product formulations or process loops as a preventative anti-foaming component to suppress micro-foam generation over long operational cycles.

2. High-Density Water Dispersibility without Separation

Formulated with specialized dispersants, this 100% solid content active agent rapidly and uniformly distributes itself upon contact with water. It eliminates common polyether processing risks such as oil spotting, chemical stratification, or substrate marking, making it highly reliable for sensitive surface-finishing industries.

3. Clean Chemistry with Lower Additive Consumption

Because LY-XP206 is a 100% active chemical substance without water fillers, its required active dosage is significantly lower than that of conventional watered-down emulsions. This ultra-low addition threshold reduces the risk of chemical build-up or carryover, preserving the structural and chemical balance of your white water or chemical stream.

4. Robust Universal Compatibility Across pH & Thermal Fluctuations

The non-emulsion, polyether ester chemical architecture of LY-XP206 is inherently stable against high shear forces, mechanical pumping, and moderate chemical variations. It functions reliably across multiple water-phase industrial sectors without suffering chemical degradation or loss of anti-foaming power.

Main Product Applications

LY-XP206 is an incredibly versatile universal defoamer that spans across multiple heavy-duty water-phase processing industries:

• Paper & Pulp Manufacturing: Highly effective when used as a papermaking wet-end additive, within pulp washing/screening systems, and in surface sizing or coating preparation loops.
• Industrial Cleaning & Texturing: Optimizes foam control in high-pressure industrial spray wash lines, textile dyeing loops, and scouring baths.
• Environmental & Infrastructure Systems: Controls foam in aeration basins and clarifiers within municipal and industrial sewage treatment facilities, as well as in cement cementing operations.
• Chemical Synthesis & Bio-Processes: Suppresses gas-liquid foam buildup during chemical reactions, blending, material transport, and biological fermentation cycles.

Application & Dosage Guidelines

To capture the highest defoaming response and ensure uniform dispersion, implement the following protocols:

• Recommended Dosage Range: Typically runs between 10 to 1,000 ppm based on the total volume of the target foaming system. The optimal dosage should be determined by customers through scaling tests under actual on-site working conditions.
• Feeding Flexibility:
• Direct Feeding: If the foaming system has sufficient mechanical agitation or turbulent flow to ensure complete, uniform dispersion, LY-XP206 can be metered into the loop directly without pre-dilution.
• Diluted Feeding: Can also be pre-diluted with clean water for precise continuous metering pump distribution.

Packaging, Storage & Safe Handling

• Logistics Packaging: Shipped in high-density 25 kg, 50 kg, 200 kg plastic drums, or 1-ton (1,000 kg) IBC tote containers to accommodate diverse chemical storage infrastructures.
• Storage Temperature: Store in a cool, dry, and sheltered location at ambient temperatures between 0°C and 30°C. Keep completely away from direct heat sources and intense sunlight exposure.
• Chemical Stability & Prohibitions: Maintain general chemical storage protocols. Do not add acids, alkalis, salts, or other foreign substances directly into the chemical container. Keep the container tightly sealed when not in active use.
• Long-Term Storage Handling: If minor product stratification or separation occurs after extended periods of storage, simply stir or agitate the product well before use; this is a normal physical behavior and does not affect technical defoaming performance.
• Shelf Life: Guaranteed for 6 months from the date of manufacture when stored unopened under the recommended storage conditions.
