Silicone rubber is an elastomer composed of
silicone(present in silica) together with carbon,oxygen and hydrogen
in 1930,james Franklin Hyde Ran The First Research To
Produce Commercial Silicones.
Silicon is an element which is present in silica (sand)
while silicone rubber is manufactured by extracting silicon from silica and
passing it through hydrocarbons. It's then mixed with the other chemicals to
create silicone.
A silicone or polysiloxane is a polymer made up of
siloxane (−R2Si−O−SiR2−, where R = organic group).
