In the vast landscape of industrial chemicals, defoamers play a critical role in ensuring the smooth and efficient operation of numerous processes. Among the various types available, mineral oil-based defoamers have carved out a significant niche due to their unique properties and cost-effectiveness. As a leading supplier and manufacturer in China, we are proud to offer high-performance mineral oil defoamers, such as our DF190, designed to meet diverse industrial needs.

What are Mineral Oil-Based Defoamers?

Mineral oil-based defoamers are a class of chemical additives primarily formulated from refined mineral oils, which are derived from crude petroleum. Unlike silicone-based or organic defoamers, their composition is relatively simple yet highly effective. They often incorporate other components like hydrophobic particles or surfactants to enhance their spreading, penetration, and bubble-collapsing capabilities. The typical appearance is a pale yellow liquid, making them easy to handle and incorporate into various systems.

Mechanism of Action

The primary mechanism by which mineral oil defoamers work involves disrupting the stability of the foam lamella. When introduced into a foamy system, the defoamer, possessing a lower surface tension than the surrounding liquid, spreads rapidly across the surface of the foam bubbles. This spreading action causes the thin liquid film of the bubble to thin and eventually rupture. The mineral oil then forms a thin, cohesive layer that prevents new bubbles from forming, effectively eliminating and controlling the foam.

Key Properties and Benefits for Industrial Applications

Our DF190 Mineral Oil Based Defoamer embodies the key advantages of this product class:

  • High Defoaming Strength: It provides potent and rapid foam elimination, crucial for processes where foam buildup is problematic.
  • Long-Lasting Effectiveness: The defoaming action is sustained, reducing the frequency of application and improving overall process stability.
  • Broad Compatibility: It performs well in a variety of systems, including those with medium to high viscosity, and is widely used as a chemical auxiliary in industries like coatings, adhesives, textiles, and rubber manufacturing.
  • Cost-Effectiveness: Offers a superior cost-performance ratio, making it an economical choice for large-scale industrial operations.
  • Ease of Use: Its liquid form and good dispersibility allow for straightforward addition and integration into manufacturing processes.
  • Safety Profile: Many mineral oil-based defoamers, including our DF190, are considered non-hazardous, contributing to a safer working environment.
