Silicone Elastomers for rubber industries
> Why choosing Silicone Elastomers?
n Macromolecules with unlimited
structural possibilities
Silicones (or polyorgano-siloxanes) have a chemical
structure based on alternating units of silicon and
oxygen. The originality of silicones compared with
natural silica, lies in the organic, carbon-containing
groups that are included in their molecular
framework.
According to the type of organic groups attached
in this way, and the production and compounding
methods used, a great variety of products can be
obtained: their final texture can be free flowing,
viscous or paste-like, elastomeric or even rigid.
n A mineral - plastic hybrid
The difference between silicones and other organic
polymers (i.e. plastics) lies in the fact that they
contain a semi-inorganic element, silicon bonded
to oxygen atoms with Si-O- bonds.
The bonds formed between the silicon and oxygen
atoms go to make up the macromolecular framework
and are exceptionally stable. They are much more
difficult to break than the carbon-carbon bonds
found in organic polymers.
n Stable, high performance polymers
Silicones outperform most other polymers: Silicones
have remarkable spreading capability coupled with
outstanding resistance to extreme temperatures,
UV and IR radiation as well as to attack from a
multitude of other external agents. Without question,
means that silicones rank among the very highest
performance polymers.
n A wide range of applications
Silicone elastomers, outstanding properties are used
for many different industrial applications: piping
in fluid circuitry and sealing (joints for building
construction and aeronautical application,
automotive gasket, boots and hoses), electrical
protection (office equipment, safety cables and
insulators for electrotechnical applications, spark
plug boots, cables and connectors for automotive
application). Food, pharmaceutical and biomedical
applications (tubes, profiled sections) are made using
heat cure elastomers from the Silbione range, which
are specially formulated to comply with European
and American regulations.

Heat resistance
Oil resistance
In order to produce products answering
strict criteria in terms of heat resistance,
Bluestar Silicones developed a very high
temperature resistance range, which
can resist until 300 °C without significant
deterioration of its properties.
Bluestar Silicones also offers a complete range
of additives allowing the improvement of the
heat stability of all master batches.
Generally, the aggressiveness of the engine oils with elastomers increases
with temperature, and espacially with temperatures higher than 100-120 °C.
Beyond 150 °C, only silicones can ensure a sufficient sealing for automobile
gasketing.

Rhodorsil® FIM
polyaddition HCR
for increased productivity
Optimized productivity is often achieved by complex mold design
(increasing number of cavities). This in turn makes temperatures and
material critical parameters more difficult to control. Part quality can
consequently suffer with anormally high reject rates.
Constantly at the forefront of innovation, Bluestar Silicones is offering
a range of platinum catalysed silicones (polyaddition reaction):
> Rhodorsil® FIM polyaddition HCR (Fast cure Injection Molding).
> Rhodorsil® FIM polyaddition HCR can be easily processed using mold
and injection presses already used in the rubber industry, without further
investment.
> Advantages of Rhodorsil® FIM
polyaddition HCR
n Significant increase in productivity
> Cure kinetics 2 to 3 times quicker than those measured on peroxide grades.
n Outstanding processability
> Excellent demolding (no surface tack).
> Significant reduction in reject rate: very good tear strength at high temperature,
curing relatively insensitive to temperature uniformity (complex molds,
multi-cavity molds, thick-section part, etc.).
n Very good mechanical properties
> Excellent compromise between elongation at break /
tear strength / compression set.
n Low temperature curability
> Energy savings, insert molding of sensitive parts.
n Respect for the environment and improved conditions at work
> Free of peroxide residues.
> Odorless vulcanizing.

n Performance
> Ready-mixed compounds supplied within the best lead times.
> Analytical report on the characteristics and performance levels
compared with the specifications and special requirements, advice
on specialized testing laboratories, etc.
“Mix & Fix Centers®” have the job of preparing samples for approval
and delivering special ready-mixed products, in the best timing.
“Mix & Fix Centers®” represent an invaluable potential resource for rubber
converters, engineering offices, R&D establishments and materials testing
facilities.
> Rhodorsil® FIM polyaddition HCR offers
the possibility of optimizing molding
characteristics to your requirements.
When using peroxide blends, it is common to vary
the peroxide content to improve the scorch time.
The small gain in scorch time obtained is always
accompanied by a significant change in cure rate
and cross link density.
Reduction in reject rates
It is also possible to increase the scorch time
(TS2) by reducing the mold temperature without
significantly affecting productivity. For peroxide
blends, a lower molding temperature causes
a dramatic increase in cure time.

Impact of temperature variations
TS2
Time
With peroxide blends, these temperature
differences can cause wide variations in
cure kinetics and in the elastomer’s physical
properties: in a multi-cavity mold, certain parts
can be correctly cured while others are still under
cured.
n Rhodorsil® FIM
Torque
The platinum system in Rhodorsil® FIM
polyaddition HCR means that the cross link
density changes very little: the end properties
of the elastomer are uniform and all the parts
in a complex mold are cured at the same time.
TS2
Torque
Depending on the geometry of the molded part
and elastomer used, the temperature can vary
by between 10 and 20 °C from the center to
the mold surface.

Torque
The graphs opposite illustrate the differences between the two reactions.
The graph for platinum, due to a very high cure rate, reaches maximum torque
very quickly. The much quicker kinetic of Rhodorsil® FIM polyaddition HCR
causes a significant reduction in finished article production costs.
The injection-molding cycle time can be cut by two or even three times
compared with peroxide versions, according to the dimensions and complexity
of the part to be molded.
The much slower cure rate of peroxide elastomers means multi-cavity molds
must be used to achieve reasonable production yields. It becomes more
difficult to achieve optimum quality levels and reject rate increase.
The much faster cure rate of Rhodorsil® FIM polyaddition HCR enable less
complex molds to be used (cheaper to produce). Better temperature control
and better control of material flow properties make it possible to produce
finished parts to much tighter specifications.

Safe and biocompatible
High level of transparency
The carefully selected components that make
up Silbione® HCR’s enable safe articles to be
manufactured according to the criteria set down
in the Pharmacopoeia. When processed under
optimum conditions, the articles meet the
biocompatibility criteria generally applicable to
products based on silicone elastomers such as:
> the absence of hemolysis
> the absence of tissue and bacterial adhesion.
Silicones have these qualities due to their ability
to produce non-polar surfaces which therefore
have very little interaction with biological systems
and pose no health risks.
Silbione® HCR’s high level of transparency
is achieved through the use of products with
a very high level of purity enabling excellent
observation of conveyed liquids.
Absence of nitrosamines
The high transparency, combined with the absence
of nitrosamines in Silbione® HCR master batches,
makes them ideally suited to producing articles
for infant applications (baby bottle teats, soothers,
toys). Tests have been performed to demonstrate
the absence of nitrosamines. The reports are
available upon request.
Conformity with regulation
The elastomer obtained by curing and post-curing
Silbione® HCR master batch for 4 hrs at 200 °C
only contains substances authorised by the
following regulations:
> France: Journal Officiel dated Nov. 25, 1992 Brochure 1227.
> Italy: Gazetta Officiale decreto 1973 and
addendum.
> Germany: BfR Part XV Silicones.
> USA: FDA Code of Federal Regulation 21 Chap. 177.2600.
Very low level of post-curing
Due to the low volatile content in Silbione® HCR
master batches, these products conform to
regulation after short post-curing cycles such
as 4 hrs at 200 °C. The recommended minimum
amount of air is 100 l/min per kg rubber.
Excellent mechanical
characteristics
The mechanical characteristics of Silbione® 71000
series HCR’s are particularly well suited to these
application types:
> tear strength, tensile strength especially for infant
applications
> high resilience for drain and catheter applications,
and peristaltic pump accessories.

Silbione® LSR*
for food contact, pharmaceutical
and health care applications
The Silbione® LSR range is well adapted to pharmaceutical and
health care applications due to the good biocompatibility of silicone
and their ability to produce non polar surfaces which therefore have
very little interaction with biological systems. Due to their high level
of mechanical properties and clarity, Silbione® LSR are particularly
suited for highly transparent molded parts such as baby nipples,
pacifiers, stoppers and valves. These grades show an excellent
resistance to standard sterilization technologies.

In accordance with the directive
-
Not in accordance with the directive
Color Master Batches for Rhodorsil® HCR comply with European
directives 2005/95/EC (ROHS) and 2002/96/EC (WEEE).
Recommended levels and colors
The colors are tuned by trichomatic spectrometry to minimize
the variation of shade from one batch to another.
High temperature performance
Master batches for silicone heat cure elastomers from Bluestar Silicones
have particularly good resistance to thermal aging (and in the case of the
“THT” range, extremely good resistance) they have been selected for their
outstanding resistance to high temperature over extended periods.
SIL 10 005 3-Add1
Quality and consistency of the colors
pemaco- Photos : Bluestar Silicones
The recommanded levels are 1,2% for most color master batches but
for grey and black colors 0,4 to 0,5 % are sufficient.
The above recommanded levels give the shade of colour in ASTM slabs using
Rhodorsil® MF 175 USP catalysed with 2,5 -dimethyl -2,5 di(tertiobutylperoxy)
hexane, cured 10 min. at 170 °C and post-cured 4 hours at 200 °C.
