CREATING TOMORROW’S SOLUTIONS
SOLID AND LIQUID SILICONE RUBBER
IN BRIEF
EL ASTOSIL ® SILICONE RUBBER:
NATURALLY VERSATILE
2
SILICONE EL ASTOMERS
AND THEIR SPECIAL PROPERTIES
Silicone rubber differs from other
elastomers in its unparalleled
property range. Of particular interest
are the characteristics resulting
not from additives or surface
treatment, but from the polymer and
filler structure. These are inherent
properties of WACKER’s rubber.
ELASTOSIL®, LUMISIL®, SILPURAN ® and SILMIX®
are registered trademarks of Wacker Chemie AG.
ELASTOSIL® silicone rubber withstands
continuous high temperatures and
dynamic stress, and thus represents
the perfect solution for turbocharger
hoses
All ELASTOSIL® silicone rubber grades
have good mechanical properties.
Specialty grades have very high tear
resistance, making them ideal for bottle
nipples and pacifiers
Typical Properties
ELASTOSIL® silicone rubber is extremely
resistant to high and low temperatures
(-50 °C to +250 °C; specialty grades:
-110 °C to +300 °C) with only slight
changes in physical properties between
-50 °C and +180 °C. The rubber’s other
typical properties include its resistance
to chemicals and environmental influences, its lack of odor and taste (many
grades conform to BfR and FDA regulations), its water-repellent surface, and its
high transparency and good processability. Many other properties can be modified with additives.
At a Glance
• Outstanding low-temperature flexibility
and high-temperature resistance
•Excellent compression set
•High resistance to chemicals and
environmental influences
•Water-repellent surface
•High transparency; can be pigmented
as desired
•Good mechanical properties
•G ood flame resistance; non-toxic
combustion products in the case
of fire
•Odorless and tasteless
•Can be easily processed
•Can be adjusted electrically from
insulating to semiconducting
•High radiation resistance

SOLID SILICONE RUBBER
EL ASTOSIL ® R AND EL ASTOSIL ® R PLUS
Solid silicone rubber bar
(standard supply form)
Extrusion of ELASTOSIL® solid silicone
rubber
WACKER offers two product ranges
based on solid silicone rubber:
A line of peroxide-curing grades marketed as ELASTOSIL® R and a line of
addition-curing (platinum-catalyzed)
grades marketed as ELASTOSIL®
R plus. You can choose between our
ready-to-use blends or our basic rubber. Our product offering is rounded
out by crosslinkers, stabilizers, colorants and other additives.
Supply Forms
The standard delivery form is as
bars measuring 90 x 100 mm (crosssection), which are wrapped in PE film
and shipped in cartons. For special
requirements, we also offer our readyto-use blends in the form of strips,
round-cords, pellets and profile strips.

Processing
ELASTOSIL® solid silicone rubber
can be processed using the standard
methods, e. g. extrusion, molding
(injection, transfer or compression
molding) and calendering.
Customized Compounds
Under our SILMIX® trademark, we
develop, compound and produce customized, ready-to-use blends for you
at our sites around the world – always
maintaining our high WACKER quality
standards.
LIQUID SILICONE RUBBER
EL ASTOSIL ® LR
Demolding an injection-molded sheet
from the mold
ELASTOSIL® liquid silicone rubber is supplied in
drums (A and B components)
At WACKER, we market liquid silicone
rubber grades as ELASTOSIL® LR
(LR = Liquid Rubber). These twocomponent, addition-curing (platinumcatalyzed), pumpable rubbers can be
injection molded and cured at high
temperatures and very short cycle
times.
Supply Forms
The A1 and B2 components are delivered
in 20-kg or 200-kg containers:
• 20-kg pails with a PE inliner
(inside ø 280 mm)
• 200-kg drums with a PE inliner
(inside ø 571.5 mm)
Multicomponent Parts
You can use our self-adhesive grades
to produce multicomponent parts by 2K
injection molding, e.g. hard-soft or softsoft combinations (color combinations
or combinations of grades with
different hardnesses).
Processing
ELASTOSIL® LR liquid silicone rubber
is processed by injection molding,
which allows for complex part geometries, precise dimensions and fully
automatic production, without the
need for secondary finishing.
Colors
Additionally, we supply colors whose viscosity matches that of our silicone
rubber grades.
1 Contains platinum catalyst
2 Contains crosslinker
