Key Differences
RTV (Room-Temperature Vulcanizing) is a term that describes the curing process where certain compounds, often silicones, vulcanize or set at room temperature. Silicone, on the other hand, is a synthetic polymer comprising silicon, oxygen, carbon, and hydrogen. These materials possess unique properties making them versatile in various industries.
For RTV, its ability to cure without the need for added heat is a distinct advantage. Meanwhile, Silicone, owing to its stability, flexibility, and resistance to water and many chemicals, finds its use in a myriad of applications, from cookware to medical devices.
Both RTV and Silicone are closely related in that RTV silicones are a subgroup of silicones that cure at room temperature.
While all RTV products are silicones, not all silicones are RTV.
