WHAT ARE CHEMICAL MASTERBATCHES?
A chemical masterbatch is the high shear
blending of a chemical(s) into a polymeric
binder system resulting in a homogeneous,
single-phase blend. This product is then
made available to the customer, in various
physical forms, for easy dispersion into a
rubber compound.
BENEFITS OF USING CHEMICAL
MASTERBATCHES
For Akrochem, the term “Chemical
Masterbatch” refers to a wide range of
polymer-bound, pre-dispersed products.
Benefts of using Akrochem’s polymer bound
dispersions include:
•
Good dispersion and uniform distribution of
the active chemical.
•
Pre-dispersed chemicals only need to be
blended into a compound instead of mixing
or shearing.
•
Rapid incorporation of the active
ingredient(s).
•
Greater batch-to-batch uniformity.
•
Improves accuracy of additions.
•
Improves handling and reduces dust.
•
Reduces health and safety concerns by
reducing exposure to hazardous chemicals.
•
Improves quality.
•
Shortens mixing cycles.
•
Reduces “fy loss”.

NOMENCLATURE
Akrochem chemical masterbatch products are
identifed by the following technical properties:
ACTIVE CHEMICAL, CONCENTRATION,
BINDER SYSTEM, PHYSICAL FORM, COLOR
As an example: a 75% MBTS dispersion in EPR
would be named AKROSPERSE MBTS 75/EPR/S,
and would be defned as follows:
MBTS
Active Chemical
“MBTS”
75
Concentration
75% Activity
EPR
Binder System
EPR Rubber (Elastomer)
S
Physical Form
Slabs
Where applicable, a color code would follow
the physical form. If the above product
was blue in color, the name would read:
AKROSPERSE MBTS-75/EPR/S-B. The “B”
indicates the color “blue”.
