Where these two actually differ
- We flag Polycarbonate degradation under UV and heat stress and Synthetic rubber gasket degradation or leaching on the LifeProof 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 LifeProof.
- The LifeProof is Polycarbonate and synthetic rubber 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 LifeProof grade, at 45% 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 →
