PossibleMold or bacterial growth in surface texture
Where these two actually differ
- We flag Bacterial or mold growth if unmaintained and Migration of manufacturing residue or plasticizers on the Pyrex 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 Pyrex.
- The Pyrex is silicone 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 →
