Silicone vs. Silica: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 4, 2023
Silicone is a synthetic polymer made from silicon, oxygen, and other elements, while silica is a natural mineral composed of silicon and oxygen.

Key Differences

Silicone is a versatile synthetic compound made from silicon, oxygen, carbon, and hydrogen. It is known for its flexibility and heat resistance. In contrast, silica, or silicon dioxide, is a natural mineral found in sand, quartz, and certain types of rock.
