Black & White Silicone Work Mat - 20" x 20" vs Silicone Grip Mat: which is safer?
Silikomart Silicone Grip Mat is the clear pick. Black & White Silicone Work Mat - 20" x 20" carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Silicone leaching (oligomers) and Mold and bacterial growth if wet-stored on the Good Cook 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 Good Cook.
- The Good Cook is silicone work mat 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 →
