Are silicone spatulas safe for high-heat cooking?
Caution. Most silicone kitchen tools are stable up to 230C, but filled or low-quality silicone may leach chemicals at high temperatures. Look for 100% food-grade silicone.
What's actually in it
Silicone spatulas and kitchen tools are made from polydimethylsiloxane (PDMS), a silicon-oxygen polymer. Food-grade silicone is generally considered stable at temperatures up to 230C. However, not all kitchen silicone products are 100% pure silicone. Some cheaper options are "filled" with silica or use plasticizers, colorants, and stabilizers that may not withstand high heat as well as pure silicone.
The silicone base is relatively inert, but the chemical additives used in manufacturing vary significantly by product quality and country of origin.
What the research says
Research on silicone food contact materials found that migration from silicone increases at higher temperatures and is higher for low-quality products that contain fillers. A 2026 review of food contact material safety found that silicone additives and cyclic siloxanes (breakdown products of silicone) can migrate into food at cooking temperatures, particularly when the silicone is hot and in contact with fatty foods.
High-quality, 100% food-grade silicone without fillers shows minimal migration under normal cooking conditions. The concern is primarily with low-cost products from manufacturers with less quality control.
