What’s the difference between Silicon and Silicone?
General News & Events, Educational - 4th Dec, 2019

Here’s a few Facts about ‘Silicon’

  • Silicon is a chemical element with the symbol Si and atomic number 14.
  • It is a hard and brittle crystalline solid with a blue-grey metallic lustre and is a tetravalent metalloid and semiconductor.
  • More than 90% of the Earth’s crust is composed of silicate minerals, making silicon the second most abundant element in the Earth’s crust (about 28% by mass) after oxygen?
  • Its melting and boiling points of 1414 °C and 3265 °C respectively are the second-highest among all the metalloids and nonmetals, being only surpassed by boron.
  • Silicon is the eighth most common element in the universe by mass.
  • Silicon and Silicates are widely used in Industrial Construction materials, Ceramics, Glass, Electronics, Steel Refining, Aluminium and Chemical Industries.
  • It was the dominant material of the ‘Silicon Age’ (the late 20th century to early 21st century) – being an important element in high-technology semiconductor devices.
  • Silicon is the basis of widely used synthetic polymers called Silicones – such as the specialised elastomer Sheetings and manufactured Components J-Flex supply to many industries around the world in demanding applications.

A few Facts about ‘Silicone’ (rubber)

  • Silicone rubber is an elastomer (rubber-like material) composed of silicone (which itself is a polymer).
  • Silicone contains ‘silicon’, together with carbon, hydrogen, and oxygen.
  • Silicone rubbers are widely used in industry, and there are multiple formulations and speciality types.
  • Silicone rubbers are often one or two-part polymers, and may contain fillers to improve properties or reduce cost.
  • Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from −55 to 300 °C (−67 to 572 °F) while still maintaining its useful properties.
  • Due to its properties and ease of manufacturing and shaping, silicone rubber can be found in a vast variety of products and applications.
  • Silicone rubber sheetings and custom rubber components are exported by J-Flex to over 55 countries, satisfying many demanding criteria in these Markets.
