Norpro Flexible Gripping Cutting Mats Set of 4, Is It Non-Toxic?
Lower concern. Silicone or rubber mats unlikely PFAS, no coating.
Flexible cutting mats are usually made from silicone or rubber without nonstick coatings. Norpro discloses nothing on PFAS, but the material itself presents lower inherent risk than coated cookware.

Is Norpro Flexible Gripping Cutting Mats Set non-toxic? What it is made of
Norpro flexible cutting mats are silicone or synthetic rubber compounds, not coated ceramics or enameled surfaces. These materials are thermally stable, non-reactive with food, and do not leach plasticizers or heavy metals under normal kitchen use. Unlike traditional plastic cutting boards, silicone mats do not degrade into microplastics when scored by knives, and they are inherently low-migration materials approved for food contact by the FDA.
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.
Silicone leaching at high temperature
Food-grade silicone is stable under normal kitchen conditions, but prolonged exposure to temperatures above 480°F or direct flame contact may release small amounts of oligomers. This risk is low for typical cutting-board use (ambient to warm water), but relevant if mats are used as oven liners near heating elements.
Bacterial growth and maintenance
While silicone resists bacterial colonization better than wood, crevices or permanent scoring can harbor pathogens if mats are not thoroughly cleaned and dried. Regular hand-washing and air-drying are sufficient to prevent hygiene issues.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Microplastic shedding
Silicone mats do not shed microplastics when cut or scraped, unlike polyethylene or polypropylene boards. This is a significant advantage over plastic alternatives in the cutting-board category.
Lead
Silicone and rubber compounds used in food-contact mats do not inherently contain or leach lead or cadmium. No recalls or contamination reports exist for Norpro mats in this product line.
Source, ATSDR ↗Coating degradation or delamination
Silicone mats are not coated; they are homogeneous material. Unlike enameled or ceramic-coated cookware, there is no glaze or coating layer to chip, crack, or release particulates into food.
How is this PFAS grade calculated?
The brand's record and disclosure
Norpro is a privately held kitchenware manufacturer with no widely documented safety controversies or product recalls tied to this mat line. The brand does not publish detailed material certifications or third-party testing summaries on its website, which is typical for mid-market cookware suppliers. No formalized sustainability or chemical-disclosure commitments are on record, but absence of reported harm or regulatory action suggests baseline compliance with food-contact regulations.
How it compares in its category
Silicone mats have lower concern than polyethylene boards, which shed microplastics, and lower concern than ceramic or melamine alternatives, which have been linked to cadmium or lead contamination. Compared to laminated wooden boards, silicone eliminates bacterial harboring in cracks and does not require mineral-oil treatment. They are chemically simpler than non-stick cookware coatings (which carry Teflon-type coating/fume concerns) and do not involve the glaze-leaching variability of traditional ceramics.
If you buy it
Silicone mats are heat-safe to roughly 400-480°F; avoid prolonged direct contact with stovetop flames or oven racks above that range, as some formulations can soften or off-gas at extreme temperatures. Hand-wash or use low dishwasher cycles to extend lifespan and avoid any potential thermal stress from very hot water. Replace if you notice permanent discoloration, stickiness loss, or visible pitting; a properly maintained set typically lasts 5-7 years. Store flat or loosely rolled to prevent permanent creasing.
