Joseph Joseph · Silicone Cutting & Prep Boards
World Market Joseph Joseph Pop Reversible Chopping Mats, Are They Non-Toxic?
Silicone with no coating described, and no PFAS statement from the brand.
The product information we reviewed describes silicone and polypropylene mats, with no applied coating named. Silicone releases food on its own, so a non-stick claim on a silicone product describes the material rather than a coating. The brand has published no PFAS statement for it.

Are World Market Joseph Joseph Chopping Mats non-toxic? What it is made of
These mats combine food-grade silicone (the main cutting surface) with polypropylene (PP) backing. Silicone is a high-molecular-weight polymer that does not leach BPA, phthalates, or other typical plastic endocrine disruptors because its backbone is silicon-oxygen bonds, not carbon chains. Polypropylene is a thermoplastic with a higher heat tolerance than many plastics (around 120C continuous use) and has not been associated with leaching of hazardous chemicals under normal food-prep conditions.
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.
Polypropylene degradation or additive leaching
Polypropylene backing may contain stabilizers or colorants not disclosed on packaging. In normal room-temperature or warm-water contact, PP presents lower concern, but migration of proprietary additives has not been tested or disclosed for this specific product.
Surface contamination or bacterial trapping
Silicone can harbor bacteria in surface texture or seams if not cleaned regularly and thoroughly dried. While not a manufacturing defect, the reversible design and dual-sided use mean cross-contamination risk is present if mats are not separated between raw and cooked foods.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Silicone leaching (thermal stress)
Food-grade silicone is chemically stable up to high temperatures and does not leach toxic breakdown products under normal kitchen use. No documented cases of silicone cutting mat leaching have been reported in peer or consumer literature.
Microplastics
Silicone mats do not shed microplastics during normal use or cutting because silicone does not fragment like rigid plastics. Wear occurs only after years of heavy use and manifests as visible tears or stickiness, not invisible particle release.

No formaldehyde-based finishes are typical of silicone or PP food-contact articles. If present, adhesive between silicone and PP layers could theoretically contain formaldehyde resin, but no disclosure or alert exists for this product.

The brand's record and disclosure
Joseph Joseph does not publicly issue PFAS statements or detailed material safety disclosures for this product line. The brand is known for design-forward kitchen and storage products but has not faced documented recall or safety controversy for silicone mats. World Market's private-label sourcing adds a layer of supply-chain opacity, but no third-party testing or complaints specific to these mats have been widely reported.
How it compares in its category
Silicone cutting mats have lower concern than vinyl or PVC alternatives because silicone chemistry avoids phthalate plasticizers. They are also more durable and easier to sanitize than rubber or wood. Joseph Joseph's reversible design is a functional standard in this segment; competitors (OXO, Oxo, generic brands) use identical silicone-plus-backing constructions with similar material profiles.
If you buy it
Hand wash or place on the top rack of a dishwasher; silicone tolerates normal dishwasher cycles well. Do not expose to direct flame or prolonged heat above 200C (400F), though normal stovetop or oven prep remains well below that threshold. Replace the mat if silicone becomes sticky, develops visible tears, or odor changes appear (very rare). Store flat or rolled loosely to prevent permanent creasing.
