Extreme Environments: Avoid severe impacts below -20°C
Chemical Exposure: Immediately rinse with clean water after contact with strong acids or alkalis

Technical Q&A

Q1: Does the case become brittle in extreme cold?
A1: Our engineering-grade PP material maintains excellent toughness at -20°C. Lab tests show impact strength at -20°C retains 60% of room-temperature performance, significantly outperforming standard materials.

Q2: How can the actual load-bearing capacity be verified?
A2: We conduct load testing on samples from each production batch and provide test reports. Users can also perform a simple test: load the case with its rated weight, drop it from a height of 30cm, and inspect the case's condition.
