Antifoam Agents

It is hard to imagine life without the foam found in everyday products like shampoos and washing detergents. However, in the industrial world, foam is a major source of trouble. These foam-related troubles are not limited to easily recognizable issues such as;

  • Process fluctuations
  • Poor washing, filtration, and drying
  • Reduced pumping efficiency
  • Thermal insulation - poor temperature control
  • Floatation of solids
  • Reducing vessel capacity
  • Preventing distillations
  • Increasing packaging (bottling) times

Antifoams are chemically designed to prevent the formulation of foam, de-foamers break the existing foam. Our antifoams are readily dispersible, provide excellent long-term foam control persistency, are highly effective on entrained, surface macro-foam and micro-foam.

There are three types of defoaming actions: foam-breaking, foam-suppressing, and deaerating. In the first type (foam-breaking), foam is rapidly destroyed by adding an agent to a foamed liquid. In the second type (foam-suppressing), the agent is added to the liquid beforehand, thus restricting it from foaming. In the third type (deaerating), foam from the liquid is merged into one big mass, accelerating its rising to the surface.

Our remarkable transparent antifoam agent can be used in various daily household products such as air fresheners, laundry detergents, and other cleaning products. Thanks to its specific technology, it doesn't change the appearance of the finished product while having a good knockdown and durability.

We know that the criteria for successful foam control are:

  • A lower surface tension than the foaming medium
  • Insolubility in the foaming media
  • Dispersibility in the foaming media

Antifoams should be dosed before the foam is created and should be dispersed as uniformly as possible through-out the liquid.

Our technical team is working closely with our customers and providing on-site technical support in order to solve their problems.

More expensive unit price but superior cost-performance

Cheap unit price but inferior cost-performance

Maxant Series

Defoaming, which is the speed and the extent of knock-down of the existing foam, is the immediate and often the dramatic visual wow-effect. This influences the product selection although it is rarely the key factor.

Overall in-use cost is generally determined by the antifoam durability, i.e. how frequently the antifoam needs to be re-dosed. This may require longer-term plant trials to determine.

In such cases, Maxant series are the best solution because new technological breakthroughs provide answers to the toughest situations.
