Zwilling J.A. Henckels · Grill & Oven Mats
Versatile Silicone Grill Mat For Side Shelves And
Lower PFAS concern, silicone mats rarely require Teflon-family coating coatings, but verify food-grade certification.
This grill mat is silicone-based, a material not typically treated with PFAS to achieve its properties. Zwilling J.A. Henckels makes no PFAS claim, but silicone cookware accessories carry lower inherent risk than nonstick coatings like Teflon-type coating. Confirm the product meets FDA food-contact standards for added assurance.

cookware is a category where PFAS exposure is more common.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This Zwilling mat is food-grade silicone, a synthetic rubber polymer designed to withstand high heat without breaking down into harmful compounds. Silicone does not require Teflon-family coating (Teflon-type coating) coatings to achieve non-stick properties, eliminating the primary source of PFAS in cookware. Food-grade silicone undergoes purity testing to exclude residual monomers and uncrosslinked oligomers that could leach into food at high temperatures.
The brand's record and disclosure
Zwilling J.A. Henckels is a German cookware manufacturer with a 280-year history and strong reputation for quality control. The brand does not publicly disclose detailed PFAS testing or statements for mat products, though its food-contact silicone products typically meet FDA and European Union food-contact regulations. No recalls, safety complaints, or contamination findings are on record for Zwilling silicone grill mats.
How it compares in its category
Silicone grill mats are among the safest mat options available; they avoid the leaching risks of aluminum or steel-based griddles with coating degradation. Unlike fiberglass or glass mats, silicone does not shed particles or become brittle over time. Zwilling's branded mat sits at the premium end of the category, with higher cost reflecting stricter material sourcing than budget alternatives.
If you buy it
Hand wash only; dishwasher heat and harsh detergents can degrade silicone's surface over time. Use below 400-450°F continuous heat; most food-grade silicone is rated to 500°F but prolonged exposure near that threshold may weaken the polymer. Replace if you notice surface cracks, permanent discoloration, or loss of flexibility. Store flat or rolled loosely to prevent permanent creasing.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Silicone leaching (residual oligomers)
Food-grade silicone is certified to limit extractable compounds, and no published studies document leaching of harmful oligomers from Zwilling mats under normal cooking conditions. Risk is inherent to silicone chemistry but controlled by food-contact standards.
Coating degradation and particulate release
Thermal stress and odor release
New silicone mats may emit a faint rubbery odor on first heating; this typically dissipates after one or two uses and is not indicative of toxicity. Prolonged exposure to temperatures above rated limits may cause permanent off-gassing.
Mold or bacterial colonization
Silicone's smooth, non-porous surface resists microbial growth better than porous materials. No recalls or documented contamination for Zwilling silicone mats; standard hand-washing prevents biofilm buildup.
Color dyes or additives in pigmented mats
Food-grade silicone uses FDA-approved colorants; Zwilling does not add lead-based pigments or azo dyes. No heavy metal contamination has been reported in the brand's silicone products.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
