What is the Composition of Silicone?

Silicone is a manmade polymer with silicon, oxygen, carbon and hydrogen atoms.Silicon-oxygen (Si-O) chains, commonly known as siloxane units, are the basic building blocks of silicone. The chemical composition of silicone may differ depending on the type of synthesized silicon polymer and the manufacturing process.

The silicone polymer is built on an alternating backbone of atoms of the elements–silicon and oxygen. Organic groups (methyl or phenyl) are attached to every other siilon atom. The organic groups confer the flexibility and other desirable features of silicones. Its unique properties — including flexibility, heat resistance and biocompatibility–are merely attributable to the structure of silicone on a molecular level.

Silicone vs. Plastics

Plastics and silicone are high-resilience silicone materials, with a softer appearance and malleability. The two similarities are close, but their different chemical composition makes them different. Plastic is made from carbon and hydrogen and is made from molecular components.

Types of Silicone?

Chemists say all these qualities

Sourcing Silica for Silicone

We understand that a huge variety of oil is required in our daily lives for producing the vast variety of oil that is used by people everywhere from gasoline to every piece of plastic or synthetic. Crystalline silica sand (quartz sand) is much more plentiful but still needs reclaim and transport – transporting large sand is very difficult if the soil contains a lot of fuel. On the world, the silica sands have been collected in several different locations. Most Silica Sand has been found in places where it comes from as it is used in concrete and therefore it has a high quantity for building.

How is silicone used in everyday life?

Silicones or siliconics are often seen in all manner of products from babies, through kitchenware and cooking equipment to toys.
