Where these two actually differ
- 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 Wilton.
- We flag Silicone oligomer leaching, Coating degradation over time and Bacterial growth if stored wet on the Wilton and not on the Silikomart.
- The Silikomart is silicone rubber grip mat, non-coated where the Wilton is Silicone non-stick surface, which is most of the difference in these two grades.
- The gap is 65 points, wide enough that this is not a close call, and the Silikomart is the one to buy.
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 →
