What are silicon based polymers?
A silicone polymer also known as polysiloxane is a type of polymer (inorganic polymer) that is mainly made up of polymerized siloxane (−R2Si−O−SiR2−). They are basically a type of synthetic polymer and are usually made up monomers that are bonded in long chains.
What is silicone polymer used for?
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation.
What is a possible commercial use for the silicone polymer?
They make excellent lubricants and hydraulic fluids, as well as emulsions for imparting water repellency to textiles, paper, and other materials. Silicone resins are used in protective coatings and electrically insulating varnishes and for laminating glass cloth.
How are silicone polymers made?
The main sources of silicone are natural origin silica stone (SiO2), water, and natural gas-derived methanol. From these materials, through complex chemical reactions, silicone is synthesized.
What things are made of silicone?
Silicone is often used for baby nipples, cookware, bakeware, utensils, and toys. Silicones are also used for insulation, sealants, adhesives, lubricants, gaskets, filters, medical applications (e.g., tubing), casing for electrical components.
What is silicon used for in everyday life?
Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon). These are used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel. Silicon is also used to make silicones.
How are polymers made in a lab?
The polymers which are prepared in the laboratories are called Synthetic Polymer. Synthetic polymers are derived from petroleum oil and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy.
How are silicones manufactured?
The silicone-making process involves extracting silicon from silica and passing it through hydrocarbons. It’s then mixed with the other chemicals to create silicone.

What is silicone polymer?
Silicone Polymer Silicone polymers are a class of hybrid organic/inorganic polymers, that show desirable surface properties such as low surface energy and high flexibility, which enables even a very high molecular weight chain to achieve optimal orientation at the interface.
How does silicone polymerization work?
During the polymerization process, silicone polymer is easily mixed with a polymerization initiator and the monomer used as raw material. The D 12 monomer featuring the lowest vapor pressure is more likely to remain in silicone than other monomers during the monomer removal step.
Why are silicone polymers so expensive?
Silicone polymers are expensive compared with organic polymers because of the cost of reducing silicon dioxide to silicon. In the Rochow process, this is then heated with appropriate catalysts to 300–400 °C and reacted with methyl chloride to give a range of methyl-substituted chlorosilanes.
What are silicone elastomers made of?
Most of the commercial silicone elastomers sold are composites containing a silicone polymer, a filler and a crosslinking agent. The filler may be highly reinforcing, often amorphous silica, or it may be less reinforcing, often ground quartz or calcium carbonate.
