Where these two actually differ
- We flag TPU degradation over extended UV exposure, Microplastic shedding from TPU and Mold or bacterial growth in seals (maintenance-dependent) on the Booe and not on the Pela.
- We flag Coating degradation and durability over time and Allergic contact dermatitis from plant fiber or resin on the Pela and not on the Booe.
- The Booe is Silicone and TPU where the Pela is Flax fiber and plant-based resin blend, compostable, which is most of the difference in these two grades.
- We are less certain about the Booe grade, at 35% confidence against 92%, because it discloses less.
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 →
