Multifunctional
cure activators for the sulfur vulcanization of diene rubber,
especially natural rubber. They can partly
or totally replace conventional activators based on fatty
acids (stearic acid, zinc stearate, and zinc 2-ethylhexanoate)
and impart excellent reversion resistance. They can also
be used as an effective physical peptizer for the mastication
of natural rubber to improve processability in mixing, extrusion
and molding. “LM” is designed for low shear and
low temperature mixes. |
|
As a rubber soluble zinc soap, it is used
instead of stearic acid and reduces stress relaxation and
primary creep of NR-vulcanizates, especially in combination
with soluble EV-systems. ZEH-DL is a free flowing powder;
it offers
processing advantages compared to the high viscous liquid
of ZEH. |
|
A cross-linking agent consisting of a 2:3 ratio of zinc
oxide to magnesium oxide for chloroprene compounds to reduce
scorch. |
|
Used
as an activator for thiazoles, thiurams and dithicarbomates
by supplying fatty acid and soluble zinc. |
|
|
These unsaturated fatty primary amides
function by migrating to the surface in a microscopic coating
which reduces the coefficient of friction. TR 121 (oleamide)
migrates more rapidly than TR 131 (erucamide) but has reduced
heat
stability. They function as both a lubricant and mold release
agent and their low odor make it extremely suitable for
food contact applications. *For peroxide cure systems, use
TR 141. |

|
Coated zinc oxide with 91% ZnO
for natural and synthetic rubber compounds, especially for
CR. A non-dusting powder. |
|
Coated magnesium oxide
with 75% MgO for natural and synthetic rubber compounds,
especially for CR and CSM. Provides protection against humidity
and carbon dioxide. |
|
|
These coated sulfurs contain dispersing
and wetting agents that can be added to any natural rubber
and synthetic rubber compound which is sulfur cured. They
are active dispersions of oil treated sulfur at the following
activity:
SU 95A – 95% (soluble), SU 109A – 75% (insoluble),
SU 120A – 83% (soluble), and SU 135A – 36% (insoluble). |
|
|
They
provide coupling of most non-black pigments to the polymer
backbone allowing for: improved abrasion
resistance, higher compound modulus, lower hysteresis, improved
compression set, and improved rolling resistance
in tire tread compounds and shoe sole compounds. |
|
|
This homogenizing agent is particularly
effective with those elastomer blends that tend to crumble
at the beginning of the mixing cycle. It is used to improve
the homogeneity of elastomers of different polarity and
viscosity. It also reduces bagging tendencies; extrusion
rates are increased without increasing the die swell, and
calendaring properties are improved. STRUKTOL® 40 MS
increases the green tack of many compounds although strictly
it is not a tackifier. Promix

hydrocarbons,
mineral oils and greases, it will not leach from vulcanizates,
which minimizes hardening and shrinkage. |

A nonstaining compatibilizing agent
used primarily to blend dissimilar elastomers,
including cured recycle. Improves mixing homogeneity
and reduces filler incorporation time. |
|
A complex oleochemical mixture containing
mono and di amides and metal soap. It is a unique blend of
anionic
and ionic surfactants with lubricants, and is an effective
dispersant, wetting agent and process agent in a variety
of polymer systems. |
|
For the production of compounds on open
mills or in internal mixers, the addition of this product
causes a better
plasticity of elastomers which leads to a rapid incorporation
of the fillers and other powdery ingredients. In highly
filled compounds, it counteracts the formation of filler
agglomerates. The dispersing effect supports the fine
dispersion of all mixing ingredients so that lots with uniform
properties will result. |
|

This mixture of fatty acid soaps, predominantly
calcium, is used in rubber compounds to improve the flow
properties
attributable to a considerable reduction of the viscosity
(internal friction) of the green compound. It improves mold
release, especially when complicated mold designs are involved.

of sulfur-containing compounds. Aflux 16 |
|
A synergistic blend of fatty acid derivatives
with selected polarities that provides internal as well as
external lubrication in a wide range of elastomers, resulting

|
A blend of high-molecular weight, aliphatic,
fatty acid esters and condensation products, bound to chemically
inert
fillers. A processing additive for polymers and is normally
used to improve the general compound processing without
significant influence on the physical properties. It acts
as a dispersing agent for powdered materials and can shorten
the mixing time by faster filler incorporation. The effect
of the vulcanization behavior is neutral. It can reduce
the risk of scorching particularly in highly loaded compounds.
Due to the good plasticizing properties, molds can
be filled faster with lower pressures during injection and
transfer molding. The water content in WB 212 may cause
a slight activation in compounds based on chlorosulfonated
polyethylenes or equivalent polymers.vanfre ap-2 |
