Why Silicone?

Benefits of using silicone rubber

1，TEMPERATURE

Silicone rubber is one of the few elastomers that has the ability to perform in extreme temperatures on both sides of the scale.  The range of silicone sponge products will withstand temperatures of -76°F to +446°F for sustained periods in application, whilst the special grades formulated with the addition of heat stabilisers take the maximum working temperature of the silicone as high as  +570°F.

2.  WEATHERING

Silicone has incredible resistance to weathering and environmental influences.  Over time, there is very little change to the properties of silicone when exposed to the elements.  Silicone is also resistant to ozone, oxidation, ultraviolet light, corona discharge, cosmic radiation, ionising radiation and general weathering.

3.  INERTNESS

Silicone  rubber  is  a  stable  elastomer  that  will  not  cause  staining,  corrosion, or  deterioration  of  other  materials  it  has  contact  with  and  does  not  support fungal growth. 

4.  LOW COMPRESSION SET

Excellent compression set properties of sponge silicone makes it the elastomer of choice for sealing applications at adverse temperatures ranges.

5.  VERSATILITY   

Silicone   extrusions   are   used   in   a   wide   range   of   everyday   products   and equipment  and  are  usually  used  for  sealing  applications.    Commonly  used  in industrial   and   commercial   applications   where   there   can   be   extensive temperature  variations  from  light  fittings  and  door  seals  in  ovens  to  gaskets in  HVAC  and  automotive,  especially  the  new  breed  of  electric  vehicles  being developed.
