Silicone container closure is a part of container closure
systems and is an important component in the
packaging of sterile products. It provides a complete
aseptic seal for transferring high-purity fluids.
container-closures maintain the sterility of parenteral
pharmaceuticals and prevent ingress of contamination
when a needle is inserted into a vial.
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).
