Where these two actually differ
- We flag Metal lid corrosion and leaching, Silicone or rubber gasket degradation and Thermal shock fracture from glass on the Pyrex and not on the Rubbermaid.
- We flag Microplastic shedding and oligomer release and Lid seal degradation and bacterial growth risk on the Rubbermaid and not on the Pyrex.
- The Pyrex is borosilicate glass with metal lids (likely stainless steel or aluminum) where the Rubbermaid is Plastic polymer (polypropylene/copolyester blend) with clear lids, which is most of the difference in these two grades.
Both products run through the same public rubric, which covers 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 →
