For all rubbers including moulded and
extruded goods and footwear.
Zincolet – 700
Processing Aid
Beige to Creamish Flakes
100 ± 50C *
2–5
It is a very effective dispersing aid for
white fillers. It is particularly effective in
highly loaded Silica compounds. In the
presence of silane coupling agents,
Zincolet - 700 should be added after the
silanisation process is completed.
Zincolet – RE
Processing Aid
Dark brown to Blackish brown flakes/Pellets
100 ± 50C *
4-15
It gives very good compound tack. It
improves the homogeneity of polymers
blend improving the process behavior. It
is useful in blending two polymers with
different polarities and viscosities.
Zincolet – 33
Processing Aid
Creamish Flakes
90 ± 50C *
2-5
It tend to stick less to processing
equipment. Furthermore, reduced
bagging on the open mill is given when
using it. Vulcanizates resulting from
compounds with Zincolet - 33 have
better release properties and also show
a better finish.
Zincolet – 213
Processing Aid
White to off white flakes
55 ± 50C *
1-3
It prevent sticking of elastomer and
compound to rollers. Increased scorch
safety for highly loaded compounds.
Helps in dispersing highly active white
f i l ler s and other ing redient s .
Recommended dosage for Eva sheets is
3 phr to get good expansion of Eva
sheets.
Zincolet – NK 207
Processing Aid
Creamish Flakes
65 ± 50C
2-5
It acts in non-polar elastomers
predominantly as an external lubricant
and release agent, since it has the
tendency to accumulate at interfaces,
this resulting in reduce friction and
tackiness. In practice, this effect shows
as improved extrusion rate and reduce
mill roll sticking. It polar rubber such as
NBR the internal lubrication is to force
resulting in a reduction of compound
viscosity. It has a certain alkalinity; it has
an activating effect upon the sulphur
cure. When too fast scorch is observed
in individual cases, addition of suitable
retarder should be taken into
consideration.
