Because silicone is considered chemically stable, experts say it's safe to use and likely not toxic. That's led to silicone being widely used in cosmetic and surgical implants to increase the size of body parts like the breasts and butt, for example.
Why is silicon not good for life?
In comparison, when silicon reacts with oxygen, it forms a stable lattice which is then not possible to easily eliminate from the "organism" (if the organism did indeed exist), and so a silicon-based life form would not be able to get rid of the waste products arising from its own metabolism.
Why is silicone bad for composites?
Silicone contamination from mold-release agents and other sources can interfere with interfacial bonding, decreasing the durability and performance of bonded composite structures.
Can cured silicone be recycled?
Unlike plastic, paper, glass and metals, where recycling is widely available, commercial recycling for silicone is nonexistent. A reason for this is because silicone, once cured, cross-linked or formed into rubber, can no longer be melted or reshaped. The traditional ways of recycling do not apply.
What is a recyclable alternative to silicone?
Silicone could be considered a type of plastic. It's a synthetic polymer like plastic but its chemical composition is different. Because it can be used to make malleable, rubbery products it's sometimes also referred to as a 'synthetic rubber'.
