Chemical Masterbatches

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”.

PACKAGING?
Akrochem chemical masterbatch products are
packaged in standard 50 pound or 55 pound,
corrugated boxes or 55 pound multi-walled bags;
which are available with 900 pounds per pallet.
SHELF-LIFE?
It is recommended that a chemical masterbatch
be used within eighteen (18) months from the date
of manufacture. Chemical masterbatches can be
re-qualifed if they are past their date of expiration
by submitting them for testing to determine the
quality of their function in a rubber compound. As
a convenience, Akrochem will gladly test any of
our chemical masterbatches that have expired.
STORAGE?
It is recommended that all chemical masterbatches
be stored in a temperature controlled environment
and away from heat, moisture and direct sunlight.
COMMITMENT TO QUALITY – BEFORE AND
AFTER THE SALE?
Akrochem is committed to providing consistent,
high-quality polymer bound chemical masterbatches
made from high-quality raw materials to meet the
individual needs of our customers.
Please feel free to contact your Akrochem Technical
Sales Representative or Technical Service personnel
to discuss your specifc needs.
QUALITY ASSURANCE?
Dependable products are vital to your operation. To insure the integrity
of our Chemical Masterbatches, we maintain the following safeguards.
• Incoming raw material testing, including FTIR.
• Total quality control (including Rheometer testing and Mooney
Viscosity control of MB) to ensure:
– Uniformity of dispersion.
– Consistent activity (rheometer testing).
– Ease of incorporation (Mooney Viscosity control of MB).
• Full traceability of all raw materials
