Flexible Cutting Board vs Silicone Grip Mat: which is safer?
Silikomart Silicone Grip Mat is the clear pick. Norpro Flexible Cutting Board carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Polymer leaching from heat, Microplastic shedding from wear and Bacterial growth in damaged surfaces on the Norpro and not on the Silikomart.
- We flag Siloxane leaching (low-molecular-weight oligomers), Microparticle shedding from grip surface and Mold or bacterial growth in surface texture on the Silikomart and not on the Norpro.
- The Norpro is Flexible plastic (likely polyethylene or polypropylene) where the Silikomart is silicone rubber grip mat, non-coated, which is most of the difference in these two grades.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
