Silikomart Silicone Mat Mold Greek Key Relief, Is It Non-Toxic?
Lower concern. Silicone molds are inherently nonstick; no PFAS treatment needed.
Silikomart silicone molds use silicone itself as the nonstick surface, bypassing Teflon-family coating coatings. No PFAS treatment is needed for this material type.

Is Silikomart Silicone Mat Greek Key Relief non-toxic? What it is made of
This product is a food-grade silicone mold, a thermoset elastomer polymer with no nonstick coating applied. Silicone's backbone of silicon-oxygen bonds is stable at typical kitchen temperatures and does not degrade into monomers or leach harmful compounds like BPA or phthalates. The Greek Key Relief design is molded into the silicone itself during manufacturing, not applied as a surface coating, so there is no paint, glaze, or enamel that could flake or leach lead or cadmium.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Coating degradation and flaking
Silicone molds do not flake or peel because the design is integral to the material, but repeated thermal cycling over many years can cause minor surface texture changes. This does not pose a chemical hazard; it is cosmetic wear.
Migration of uncrosslinked oligomers from silicone
Food-grade silicone may release trace amounts of cyclic siloxane oligomers into fatty or acidic foods over very long use at high temperature; levels are typically below regulatory concern for occasional use, but heavy daily use with hot oils warrants occasional replacement.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Teflon-type coating fume risk
Silicone molds have no nonstick coating; Teflon-type coating fume inhalation hazard does not apply to this product.
Lead
The Greek Key Relief is a molded feature within the silicone itself, not a painted or glazed surface. No coating is applied that could contain heavy metals.
Source, ATSDR ↗Aluminum leaching
This product is silicone, not aluminum. No aluminum contact hazard applies.
How is this PFAS grade calculated?
The brand's record and disclosure
Silikomart is an Italian cookware manufacturer specializing in silicone baking molds and kitchen tools. The company maintains EU food-contact certifications and does not have a documented history of safety violations or product recalls related to chemical leaching. Silikomart does not publicly disclose detailed PFAS sourcing or testing data, but this is common for silicone mold manufacturers because silicone itself does not require PFAS processing.
How it compares in its category
Silicone molds eliminate most hazards present in traditional metal or ceramic cookware, no lead glaze risk, no Teflon-type coating fume risk, and no aluminum leaching. They compete favorably against nonstick pans that require fluorinated coatings. Compared to reusable plastic molds, food-grade silicone avoids BPA and phthalate concerns because it does not require plasticizers to function.
If you buy it
Hand wash with warm soapy water or place on the top rack of a dishwasher; avoid abrasive scouring pads that may damage the surface. Use at temperatures up to 230 degrees Celsius (446 Fahrenheit) as stated by the manufacturer; silicone remains stable at typical baking temperatures. Over 10 to 15 years of heavy use, silicone can gradually lose elasticity and may develop minor surface stiffness, but it does not become unsafe. Store away from prolonged direct sunlight to slow any slow discoloration.
