silicone

This term refers to a specific synthetic polymer known for its stability, flexibility, and resistance to heat and water. It is frequently used in industrial applications as a sealant or lubricant, as well as in medical contexts for biocompatible implants. In common parlance, the word is often used as a metonym for cosmetic surgery, specifically referring to the gel-filled implants used for body augmentation. It is an uncountable mass noun, meaning it does not have a plural form when referring to the material itself; instead, phrases like "silicone implants" are used to count individual objects made from the substance.
