What is Foam?
What is Foam?Foam is a
mass of bubbles created when certain types of gas
are dispersed into a liquid. Strong films of
liquid than surround the bubbles, forming large
volumes of non-productive foam.The cause of foam
is a complicated study in physical chemistry, but
we already know that its existence presents
serious problems in both the operation of
industrial processes and the quality of finished
products. When it is not held under control, foam
can reduce the capacity of equipment and increase
the duration and costs of processes.

What are Antifoams
What are Antifoams? Antifoam blends contain oils
combined with small amounts of silica. They break
down foam thanks to two of silicone's properties
incompatibility with aqueous systems and ease of
spreading. Antifoam compounds are available
either as powder or as an emulsion of the pure
product.

Powder Antifoams
Powder
Antifoams Antifoam powder covers a group of
products based on modified polydimethylsiloxane.
The products vary in their basic properties, but
as a group they introduce excellent antifoaming
in a wide range of applications and
conditions.The antifoams are chemically inert
and do not react with the medium that is
defoamed. They are odourless, tasteless,
non-volatile, non-toxic and they do not corrode
materials. The only disadvantage of the powdery
product is that it cannot be used in watery
solutions.

Antifoam Emulsions
Emulsions Antifoam Emulsions
are aqueous emulsions of polydimethylsiloxane
fluids. They have the same properties as the
powder form, the only difference is that they can
also be applied in watery solutions.

Our S-series of Liquid Antifoams
Novohems Technical Data Sheet
S-ANTIFOAM EMULSIONS are high performance
silicone based antifoam emulsions containing
non-ionic surfactants and functional additives.
Foam formation is generally unwanted as it
increases viscosity and reduces the density of
liquids, thereby making stirring and transport
difficult. It can also decrease the performance
of the product, give application faults and
decreases output. These antifoams not only
effectively kill foam in low concentrations but
also do not show any adverse environmental impact
(when used in ETP) due to their inert nature
(chemically and biologically) and ability to
decompose.

Powder Antifoam S-series
PROPERTIES Antifoam powder S 17Y is an optimal
mixture of active components with an adequate
base. It is used for manufacturing cleaning and
washing substances, as well as in the chemical
and other related industries where there is a
need for preventing excess foaming.
APPLICATION The product is added into liquid or
powder formulas, must be stirred well or
dissolved completely. The dosage depends upon the
composition of the product it will be added to,
and may vary between 0.3 and 0.8 percent of the
total mixture.
