Silicone Elastomersfor electrical industries
> Why choosing Silicone Elastomers
for electrical applications?
> Composite insulators and surge arresters:
The excellent level of hydrophobicity and the
outstanding recovery of hydrophobic properties
after pollution, combined with UV and IR resistance
means that Silicones are top performers in the
polymers world.
> Potting: Very good fluidity of liquid Silicones
(RTV-1 and RTV-2) and high insulating performances
are particulary recommended in electric and
electronic fields.
> Conformal coating and insulator impregnation:
Remarkable spreadability of Silicone resins and
adhesives associated with excellent temperature
resistances are widely used for the protection
of many supports.
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, pure and high performance
polymers for a wide range of applications
in electrical industries
Thanks to specific properties of Si-O-Si bond and
ingredients purity, Silicone Elastomers show unic
properties for many different electrical applications:
> Electrical cable, junctions and cable ends: High
insulating performances with resistivity range from
10+15 to 10+16 W.cm.
> Safety cable: Thermo oxidative stability bringing
high fire resistance, high ashes cohesion and non
toxic smokes.

Bluestar Silicones offers a complete
range of silicone elastomers for the
electrical industry including numerous
different technologies.
Rhodorsil® HCR
Heat cure silicone elastomers are basically made from
reactive silicone gums, linear and specific silica fillers.
HCR have outstanding properties and are far superior to
conventional organic elastomers. They exhibit exceptional
mechanical strength at temperatures ranging from - 50° C
up to + 300° C. The aging resistance of these elastomers
highlights their fundamental qualities such as the fact
they are chemically inert, their photo-oxidative stability
and the absence of residual reactive groups once cured.
A wide range of coloring is available.
HCR are available as rubbery breads and supplied in two
forms: master batches (without incorporated catalyst)
or as ready to use compounds (through Bluestar Silicones’
Mix & Fix Centers®).
Rhodorsil® RTV-2
Rhodorsil® RTV-2’s are two-component liquid silicone
elastomers. Their cure rate is generally slow at ambient
temperature (pot life), but very quick at high temperature.
The curing rate doubles every 10°C.
Rhodorsil® RTV-2’s cure by a polyaddition reaction. They
have two parts (A and B), mixed in a ratio of 100/100
(catalyst in A part) or 100/10 (catalyst in B part). Mixing the
two components is obtained manually for small quantities
and mechanically for quantities over 1 kg, in a rotary mixer
or using dispenser pumps. These elastomers cure without
releasing any by-products and there is consequently very
little shrinkage.
Rhodorsil® LSR
LSR are bi-component systems (90/10 or 50/50) which
viscosities are generally included between 10 000 and
10+6 mPas. This type of formulation forms an elastomeric
network thanks to reactions of polyaddition in the presence
of a platinum catalyst. The processing and product
performance advantages of liquid silicon rubbers (LSR)
are utilized in many existing and new applications. This
type of rubbers can associate essential properties of silicon
polymers and easy injection molding processing.
After mixing A and B parts in a static or dynamic mixer,
the largest means of transformation are: injection-molding
machines working at medium or high pressures, or pumps
directly feeding a mold at ambient pressure. These
mixtures are vulcanizable from 60°C to around 150° C.
Rhodorsil® Resins & Adhesives
Rhodorsil® resins are siloxane polymers characterized by their
three-dimensional branched-chain structure.
Their preparation involves hydrolysis and polycondensation
of silanes (mono, di- and tri-fonctional silanes and sometimes
even tetrafonctional silanes). These “polymers”, after
completion of the reactions of polycondensation and cross
In order to answer all your needs in term
of electrical insulation, Bluestar Silicones
has developed a complementary range
including three different technologies.
Rhodorsil® CAF (RTV-1)
CAF are one component liquid silicone elastomer curing
at room temperature on contact with atmospheric humidity.
On contact with air moisture, CAF cure liberating an oxime,
an alcohol or acetic acid depending on their cure type.
Processing is particularly easy, since the products are
delivered ready to use. Application can be carried out either
manually or using robotic equipment. Their cure rate can
be considerably accelerated by increasing temperature and
humidity. After curing, CAF are transformed into silicone
elastomers offering very good mechanical properties, good
heat stability and high dielectric properties.
Rhodorsil® Pastes
Rhodorsil® Pastes are made of a polydimethyl siloxanic oil
thickened with inert fillers.
Rhodorsil® Pastes are mainly used as sealants and
electrical insulants. Their main properties are:
> High dielectric properties.
> Excellent resistance to high temperatures, without
hardening or degradation.
> Exceptional resistance to water and many chemical agents.
> Good resistance to oxidation.
> Strong anti-adherent characteristic.
Rhodorsil® ESA
Rhodorsil® ESA are two component Adhesive Silicone
Elastomers (ESA) curing very quickly (within a few minutes)
at high temperatures (+ 120° C to 200° C) - (Polyaddition
reaction). After polymerisation, Rhodorsil® ESA form a flexible
adhesive film which is particularly resistant to thermal,
climatic and environmental attacks. Rhodorsil® ESA are
designed for bonding to silicone elastomers, metal or plastic
surfaces in Electrical industries.
linking under the combined action of heat and catalysts
(siccatives), yield flexible or rigid films, always hydrophobic
and capable of resisting decomposition over long periods
of time under high temperature without depolymerisation.
Rhodorsil® RT Gel
Rhodorsil® RT Gel are two-component silicone oils curing
by polyaddition reaction. The viscosities of the two parts
are gererally included between 700 and around 7000 mPas.
This low level of viscosity allows a very easy mixing of two
components which can be performed manually or
mechanically for higher quantities (over 10Kg).
After two components mixing, the very fluid liquid is
transformed after curing into a self elastic, translucent gel.
Curing takes place without any heat release but can be
accelerated by heating.

> Advantages of Rhodorsil®
Silicone elastomers
Rhodorsil® Silicone Grades for
Composite insulators, surge arresters & cables ends
n Outstanding resistance to natural aging agents (spray,
bad weather, UV radiation, ozone, salt fog, etc.) as well as
to climatic and industrial pollution.
n Very good tracking resistance, excellent arc resistance
and electrical erosion.
n Good fire behavior.
n Stability of physical and electrical properties.
n Excellent hydrophobicity with high hydrophobic recovery
capacity in polluted area.
Bluestar Silicones offers a complete and specific range of silicone
elastomers to manufacture high performance, long life elastomeric housings
for composite insulators, surge arresters and cable junctions.
Those can be silicone rubber (HCR) or liquid silicones (LSR, RTV-2).
Thus, they offer a broad range of viscosities in perfect adequacy with
transformation techniques. These products are innovating and powerful
to adapt to the evolutions of the standards in force.

Processing method
> For the production of composite insulators and surge arrestors,
the choice of the silicone type depends on several essential parameters:
n The dimension of the article. Actually, an insulator can have very variable dimensions:
> Diameter: from a few centimeters to more than one meter
> Length: from a few centimeters to several meters.
n Production yield : limited series (hollow core type) or large series (long rod type).
n The design of the parts: simple or complex.
n Customer’s processing conditions and technical constraints.
Comprehensive technical assistance,
close at hand…
Bluestar Silicones, with its 2 Research and Development centers and its
5 European RTV and Mix & Fix production centers, has fully dedicated scientific
and technical teams providing service to those who design and produce
insulators and surge arresters.
Bluestar Silicones offers a customized service, working with them to develop
products tailored to the market, providing high technical performance
and economically competitive.

> Advantages of Rhodorsil® resins
Rhodorsil® Silicone Grades for
Coating and impregnating protection
Bluestar Silicones offer a broad range of Silicone resins. After drying
and crosslinking, these resins form flexible or rigid films that confer
remarkable properties to the treated surfaces.
Their heat stability is outstanding: resins offer effective protection
at high temperatures (typically in the range of 200°C and over
for short period of time).
They resist well to oxidation and have good dielectric properties.
These remarkable characteristics make them particularly suitable
for numerous electrical and electronic applications, such as:
insulation of printed circuit, electronic assemblies of flexible materials,
impregnation of glass cloth braids, braided cables, mica tapes,
electrical motor coils, etc.

> Advantages of Rhodorsil® Silicone elastomers
Rhodorsil® Silicone Grades for
Potting
There is no limit of the use of liquid silicone elastomers in the electrical
and electronic industries, especially when protection of components
against harmful environmental effects is required.
Encapsulating, potting, impregnating, dipping, filling and casting
are some examples of applications which can be considered.
Polyaddition curing systems are the preferred insulating materials
for these applications.
Their acceptance is due to several factors including their excellent
dielectric properties, mechanical strength, shock resistance, moisture
resistance, excellent adhesion properties, aging and chemical resistance.
Their ease of processing is also a well appreciated asset.
