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 Tech21.
- We flag Volatile organic compounds (VOC) off-gassing on the Tech21 and not on the LifeProof.
- The LifeProof is Polycarbonate and synthetic rubber where the Tech21 is Thermoplastic elastomer blend, likely TPE or similar polymer, 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 →
