Summer car interiors can exceed 140°F (60°C), causing cheap phone cases to leach chemicals or warp. Demand surges for cases made from food-grade silicone rubber with excellent temperature resilience. This material maintains elasticity and stability from -58°F to over 392°F (-50°C to 200°C), resisting deformation, softening, or odor release even on hot surfaces (like car dashboards). Consumers prioritize certified materials (e.g., FDA food-grade) for safe, eco-friendly protection in extreme heat.
