Where these two actually differ
- We flag Silicone/rubber degradation and surface pitting and Bacterial or mold colonization in grooves 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 rubber or silicone mat, uncoated where the Silikomart is silicone rubber grip mat, non-coated, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
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 →
