Where these two actually differ
- We flag Microplastic shedding, Mold or bacterial colonization, Surface discoloration or staining and Permanent deformation or tearing on the Fat Daddio's and not on the Fat Daddio's.
- We flag Silicone elastomer degradation under prolonged high heat and Mold or bacterial growth if stored wet on the Fat Daddio's and not on the Fat Daddio's.
- The Fat Daddio's is Food-grade silicone (elastomer) where the Fat Daddio's is silicone (elastomer), 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 →
