Demulsifier Additive Polyether Polymer Compounds Additive For Lubricants

Advanced Water Separation for Industrial & Marine Lubricants

It is an additive with excellent demulsification performance and is widely used in marine oil. After adding a small amount, it can not only extend the service life of marine oil, but also achieve advanced demulsification index. It can also enhance the role of other additives in marine oil and has a defoaming effect. The anti-emulsification ability of this agent in lubricating oil is equivalent to that of T1001, and it is better than T1001 in anti-wear hydraulic oil. This agent has better oil solubility than T1001 and is easy to use. It can be added at room temperature, which is conducive to use under non-heating conditions. This product is a broad-spectrum demulsifier, suitable for all oils with requirements for anti-emulsification performance, especially for marine oils with large additive amounts and high demulsification requirements.

Product Introduction

Our Polyether Polymer Demulsifier Additive leverages advanced block copolymer technology to rapidly separate emulsified water from lubricants. Engineered with optimized EO/PO ratios, this demulsifier additive destabilizes water-oil emulsions within minutes while maintaining lubricant integrity.

This innovative demulsifier additive prevents filter blockage, corrosion, and viscosity loss in systems contaminated by seawater or humidity. With its broad-spectrum effectiveness, it’s suitable for all oils requiring anti-emulsification performance, especially marine oils with large additive amounts and high demulsification requirements.

Performance Advantages

Achieves 99% water separation in <30 minutes (ASTM D1401 modified). This demulsifier additive outperforms alternatives with its rapid action.

Maintains demulsification with 5% seawater contamination (ASTM D665 B validated).

Neutralizes 8 mgKOH/g organic acids (ASTM D664).

Prevents water-induced filter blocking (ISO 4548-12 compliant).

Effective in mineral, synthetic, and bio-based oils (ISO 15380 HEES).

Why Choose This Demulsifier Additive?

“In North Sea drilling rigs, this demulsifier additive reduced water content in hydraulic oils from 2% to <0.1% within 45 minutes – eliminating corrosion-related pump failures and extending oil service life by 300%.”
– Offshore Engineering Journal, 2025 Field Report

*Third-party validated: Reduces filter replacement frequency by 80% in tidal turbine gearboxes with 3% seawater ingress (DNV GL Test Protocol 2025-07).*
Molecular Innovation:
Our star-shaped polyether architecture with 8 arms accelerates water droplet coalescence – achieving 3x faster separation than linear polymers (SAE Paper 2025-01-2085). This innovative molecular design makes our demulsifier additive the most efficient solution on the market.

Cost-Saving Advantage:
Enables 24.6% lower demulsifier dosage vs. conventional additives while maintaining effluent oil content ≤1,000 ppm (Industrial Water Treatment, Vol. 56, 2024).
