Special sole application
Evonik Gorapur GmbH is constantly developing
improved release agents in order to meet the requirements of the PU footwear industry.
All release agents can be applied by using manual spray
guns or robots.
Products for mono and dual density safety footwear are
available as concentrates, high solids or water-based
emulsions. Volatile siloxanes are used as active ingredients. These release agents are characterized by excellent properties and economical usage. The soles demonstrate dry and virtually residue-free surface properties. In
addition, the workplace remains clean during production.

Release agents for ester unit soles are available as concentrates/high solids in dilutable and ready-to-use form.
In particular GORAPUR® LS 1040, a new solvent-free
release agent, demonstrates a significant step towards an
economically and environmentally friendly shoe-soles
product. There is no painting procedure or any other
post-treatment necessary, as the soles look very mat and
uniform.
Dilutable products have a proven track record in the production of ether unit soles. They consist of modified siloxanes with excellent release properties and economical
usage. Our own source of silicones guarantees constant
quality and the ability to produce tailor-made products.
Silicone surfactants for shoe sole systems
The major advantage of the products listed below is their
ability to improve skin formation and regulate the cell structure,
making it finer and more uniform. This eventually leads to a
significant improvement in the various physical properties.
A surface active substance reduces the surface tension of the
liquid components, resulting in improved and easier miscibility.
The foam becomes more homogeneous, pigments are better
distributed and the tendency to create flow lines is reduced.
The optical appearance is significantly improved.

a) Silicone surfactants
b) Cell opener
TEGOSTAB® B 8993 is specially designed for running soles.
A finer, more uniform cell structure is obtained. It improves
the compatibility of the raw materials and enhances the
tensile strength, elongation of break and Ross-Flex properties.
TEGOSTAB® B 8948 functions as mild pure organic cell opener
and cell regulator.
GORAPUR® IMR 852 functions as potent silicone cell opener
Both reduce shrinkage in low-density foams and mid-sole
applications. Both can be used for ester and ether systems.
TEGOSTAB® B 8946 PF controls the cell size and cell-size
distribution. The dimensional stability will be improved.
TEGOSTAB® B 8952 is mainly used in mid- and low-density
ester shoe soles. It provides better skin formation and less
peeling, reduces pinholes and enhances mechanical properties.
TEGOSTAB® B 8960 is used as a co-surfactant, mainly in
mid and low-density ester shoe soles. It provides excellent
skin formation, less peeling and reduces pinholes.
c) Abrasion reducer
The footwear industry requires improved abrasion resistance
in its products. ORTEGOL® AB is the answer. It functions
as an internal abrasion reducer for densities of 500 kg/m3 or
greater and migrates to the surface of the cured elastomer.
It can be used for ester systems only.

d) Catalysts
TEGOAMIN® 100
Pure Triethylene Diamine salt.
TEGOAMIN® MEG
Solution of 33 % Triethylene Diamine in
Monoethylene Glycol. Strong gelation catalyst
for polyester microcellular foam.
TEGOAMIN® AS MEG
Acid blocked gelation catalyst for polyester
microcellular foam.
It is normally used in combination with standard
TEGOAMIN® MEG catalyst. It can be used to
increase the cream time (higher flowability)
maintaining the same demold time.
Alternatively can be used to strongly reduce
the demold time (higher productivity of
polyurethane parts) maintaining the same
cream time. It has no cross-linking effect.
TEGOAMIN® BDE
Strong blowing catalyst.
KOSMOS®
Various metal strong gelation catalysts.
e) Antistatics
Used for the production of microcellular polyurethane materials with an increased conductivity
and hence improved antistatic properties.
ORTEGOL® AST
Inorganic salt dissolved in polyol for PU ether
shoe sole systems.
Can be used as post-formulation additive.
Can be blended with other components or added
directly in the mixing head.
ORTEGOL® AST 5
Innovative antistatic for PU polyester shoe sole
systems.
Can be used as post-formulation additive.
Can be blended with other components or added
directly in the mixing head. Is very compatible
with other components, doesn’t migrate and
doesn’t affect the hydrolysis resistance. Active
even in low humidity environments.
ORTEGOL® AST 8
ORTEGOL® AST 8 is a very high and special
active antistatic. It contains no reactive solvent
and can be applied for the production of
shoe soles based on both polyester and polyether systems.
ORTEGOL® AST 8 is extremely effective so that
only a very small amount is necessary to
achieve the standard antistatic range of safety
shoes. With higher concentration very low density
antistatic insoles can be produced.
Apart from this it is also possible to achieve
microcellular polyurethane products (shoes and
others) of extremely low electrical resistance
to be used in working areas where Electrostatic
Discharge Sensitive Devices (ESDS) are handled.
ORTEGOL® AST 9
Inorganic salt dissolved in Monoethyleneglycol.
Used for PU ester shoe sole systems.
It is specially designed for self-formulators and
system-houses that could adjust the crosslinker
amount.

Silicone surfactants
for ether shoe sole
systems
TEGOSTAB® B 8905
provides a finer and more
uniform cell structure. This
improves tensile strength and
Ross-Flex properties.
TEGOSTAB® B 8930
is specially designed for ether
systems containing water as
a blowing agent. It reduces
the formation of pinholes,
gives a finer cell structure
beneath the skin and improves
the optical appearance of the
surface.
All release agents and performance additives described make a significant contribution to
problem-solving in the PU footwear industry. Our worldwide network of experts and the new
development department for shoe sole application in Essen aid in this process. Don’t hesitate to
