Walton's Flexible Cutting Mat - 24.5in x 30in
Lower concern for PFAS; silicone mats carry minimal risk profile.
Wilton cutting mats are typically silicone-based, a material with lower inherent PFAS risk than Teflon-family coating. No PFAS disclosures found.

What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
PVC leaching (if PVC composition)
Wilton does not clearly disclose whether this mat is silicone or PVC. If PVC, migration of plasticizers (including phthalates) is possible at elevated temperatures or over extended contact with fatty foods, though risk is low under normal kitchen use below stated temperature limits.
Coating or surface degradation over time
Silicone and PVC mats can lose non-stick properties and structural integrity after repeated thermal cycling and wear. Degraded surfaces may shed microparticles into food; replacement every 2-3 years of regular use is prudent to minimize this risk.
Thermal stability and fume risk above temperature limit
Silicone mats used above manufacturer limits (typically 480-500F) may emit odors or degrade chemically. This is not the same as Teflon-type coating (non-stick cookware) fume risk, but should be avoided by adhering to published temperature guidance.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Lead
No recalls or testing data suggest heavy metal contamination in Wilton's silicone mats. Food-grade silicone is regulated and unlikely to contain lead or cadmium pigments, but lack of third-party certification leaves this unverified for this specific product.
Source: ATSDR ↗Aluminum leaching (not applicable)
This mat is not cookware and does not come into contact with acidic or prolonged-heat scenarios typical of aluminum leaching; hazard class not relevant to silicone/PVC mats used for cutting and baking prep.
The full breakdown
What it's made of and why it matters
Wilton's flexible cutting mat is constructed from food-grade silicone or PVC, materials chosen for heat resistance and non-stick properties in baking and food prep contexts. Silicone mats are chemically inert at typical kitchen temperatures (up to around 480-500F depending on grade) and do not leach plasticizers like BPA or phthalates when used as intended. PVC variants, less common in premium mats, carry slightly higher chemical migration risk if the mat degrades or reaches high temperatures, though Wilton does not clearly specify which polymer is used in current production.
The brand's record and disclosure
Wilton is a long-established kitchen brand (est. 1929) owned by Smack Foods and has not been subject to major product recalls or chemical safety controversies in recent years. The company does not publish detailed material safety disclosures or third-party certifications (e.g., FDA food-contact confirmation, phthalate-free statements) on its product pages, leaving exact composition ambiguous. No documented PFAS exposure incidents are on record for this product category from Wilton.
How it compares in its category
Flexible silicone baking mats are among the safest food-contact kitchen tools available. They outperform parchment paper (which may contain PFAS coatings) and ceramic or glass surfaces in terms of chemical inertness and durability. Comparable products from brands like OXO and Artisan have similar safety profiles; Wilton's mat offers no significant material advantage or disadvantage relative to peer products at this price point.
If you buy it
Use the mat only up to the temperature recommended by Wilton (typically 480F; verify packaging). Hand-wash with mild soap and avoid abrasive scrubbers that can degrade the surface over time. Do not use under direct broiler heat or at temperatures above the stated limit, as thermal stress may increase polymer degradation. Replace if the mat becomes sticky, discolored, or shows surface cracks, which signal loss of structural integrity.
