What is Foam?

  • Foam is entrapped gas in liquid.

  • When liquids are agitated, boiled, fermented or poured, surface tensions drop down and air bubbles enter. These gas bubbles are trapped in liquid and called foam.

Types of Foam

Foams are divided into two groups according to their durability.

Macro Foam:

  • Separated by thin liquid films

  • Irregular, polygonal

  • Nondurable foam


Micro Foam:

  • Separated by thick liquid films

  • Regular

  • Durable, stubborn foam


Foam Problems in Production & Defoamers, Antifoamers

Foam in Production causes:

  • difficult dispersion

  • higher production cost

  • surface defects

  • decrease production capacity

To prevent such issues, various foam controlling agents are used

Defoamers and Antifoamers,

  • increase production efficiency

  • keep the production costs under control

  • increase the product quality


Features of Foam Controlling Agents


Defoamers are divided into two categories according to their function.

  • Defoamers: kills the existing foam

  • Anti-foamers: prevent foam formation

OFFoam®, contains both features and distinguishes itself from other foam controlling agents


How does OFFoam® work?

  • OFFoam®, strengthens bonds between liquid molecules and enhances surface tension by taking advantage of cohesive force sustained by hydrophilic & hydrophobic molecules.


  • Increased surface tension prevents foaming.

  • The same molecules move gases away from the liquid, causing the foam to dissipate.
