Dow Polypropylene Glycol (PPG)

Excessive foam can be a problem in many types of operations due to its negative impact to efficacy, productivity and cost. Foam control agents help to solve these challenges by reducing or eliminating foam. Regulation compliance plays a large role in the selection and use of chemical antifoam agents.

Dow’s line of polyglycol anti foaming agents offers a wide spectrum of physical and performance properties which can be tailored to suit each distinct defoam application. They are trusted for their known performance as processing aids, defoamer agents, foam preventers and deaeration materials in various industries.
