Properties of Silicon Rubber
2
INFORMATION

• Silicon rubber is the name we give silicon
  products because of its rubber like structure.
• Silicon rubber contains, in addition to silicon,
  oxygen, hydrogen and carbon.
• Silicon itself is a polymer, which makes the
  silicon rubber largely polymer in nature.
• Silicon rubber profile India may also contain
  fillers to make it more cost-effective or to
  enhance a certain property.
• Silicon rubber is a very high performing class of
  polymers, which is used in many critical
  applications across various industries.
• Silicon rubber has qualities that make it
  suitable for very demanding applications. At the
  same time, silicon is easy to produce and
  cost-effective.
• Hence, its usage has been steadily increasing it
  first appeared as a commercial product for
  manufacturing. Silicon rubber has certain
  properties that put it far above organic or other
  type of rubbers.

RESISTANCE TO HIGH OR LOW TEMPERATURES

• Silicon rubber has one of the best resistivity to
  temperature extremes.
• Studies have shown that it can withstand
  temperatures as high as 350ºC for short periods,
  200ºC for around 10,000 hours and 150ºC
  indefinitely.
• On the other end of the spectrum, it can
  comfortably withstand temperatures of -60ºC
  -70ºC with some products able to bear
  temperatures as low as -100ºC.
• This resistance to extreme heat and cold is one
  of the reasons for the popularity of silicon
  rubber profiles India in the manufacturing
  sector.
• Unlike other rubbers, it does not become brittle
  in extreme temperature and retains it elasticity.
• As a result, it is used in high heat applications
  like automobile engines or very cold environment
  such as in aerospace.

4
WEATHERABILITY

• Weather ability or the ability to weather
  environmental changes is very high in silicon,
  much better than ordinary rubber.
• It can be exposed to wind, rain, UV rays and sun
  for prolonged periods without any deterioration.
• It is also very good at withstanding ozone
  degradation which has very little effect on its
  integrity.
• This makes it useful for a number of outdoor
  applications, including wearable's.

5
STEAM AND MOISTURE RESISTANCE

• You can submerge silicon rubber in freezing,
  boiling or normal water fro a prolonged period
  and see virtually no change in its physical
  properties.
• This is why many underwater installations use
  silicon rubber for critical applications like
  sealing.
• Even more important is the response of silicon
  rubber profile India to steam.
• Where other rubber will deteriorate in the
  presence of steam, silicon rubber shows no
  change.
• However, it should be noted that it does react to
  pressurized steam when the pressure keeps
  increasing.
• This property is one of the reasons silicon is so
  popular as wearable's in high moisture
  conditions.

6
ELECTRICAL INSULATION

• Silicon rubber is one of the most effective
  component when it comes to insulating materials.
• Its insulating properties remain constant in
  different environments, temperatures and
  frequency, making it uniquely suitable for
  electronic insulation.

• It can withstand corona discharge and will be
  effective as insulating material even when
  immersed in water.
• Silicon rubber is today the preferred material
  when working with high voltage.

7
CHEMICAL , OIL AND SOLVENT RESISTANCE

• Like a lot of rubbers, silicon rubber also has
  high resistance to oils, chemicals and solvents.
• While silicon rubbers resistance to oils may not
  be as good as certain other organic rubbers, its
  performance under high temperature puts it ahead
  of others.
• It is largely unaffected by most chemicals and
  solvents, including polar organic compounds and
  dilute acids and bases.
• Even in non-polar organic compounds, silicon will
  not easily decompose. Some solvents can soften
  the material.
• Strong acids and bases will also adversely affect
  silicon. But on the whole, silicon has a far
  better resistivity than other rubbers.

8
FLAME RETARDANCY

• Like other rubbers, silicon rubber profile India
  is not resistant to fire, but when treated with a
  flame retardant, it shows better performance.
• It produces no noxious gas or black smoke when
  burnt. This makes it a preferred component from
  the environmental viewpoint.
• Since it does not create any harmful effects on
  burning, it is used in closed spaces and consumer
  electronics.

COMPRESSION SET

• The compression set of Silicon rubber profile
  India stays consistent even under different
  temperatures, with a better performance than
  other rubbers.
• This is why silicon rubber is used in gaskets
  where the ability of the rubber to recover from
  compressions is crucial.
• Along with its ability to adhere and release
  easily, silicon rubber makes a great sealer.
