Definition
- Noun:
- A synthetic polymer: Silicone refers to any of a large class of synthetic compounds consisting of repeating units of silicon and oxygen atoms, often combined with carbon and hydrogen. These materials are known for their stability, water resistance, and flexibility across a wide temperature range.
- A versatile industrial material: Silicone is used in a vast array of products due to its properties, including lubricants, adhesives, protective coatings, synthetic rubber (elastomers), and electrical insulation.
Usage Examples
- Noun:
- The surgeon used silicone implants in the procedure.
- Apply a thin layer of silicone lubricant to the rubber seal to prevent it from drying out.
- This high-temperature baking mold is made of flexible silicone.
Advanced Usage
"Silicone-based": Describing a product whose primary functional component is silicone.
- This is a silicone-based adhesive that remains flexible after curing.
In technical contexts: Often specified by type, such as "silicone oil," "silicone rubber," or "silicone resin," indicating its form and application.
- The laboratory uses silicone oil for high-temperature baths.
