Material & Craftsmanship
Understanding the science behind PP protection
Enhanced PP Material
Made with KeXin's proprietary enhanced PP (Polypropylene) formula, adding glass fiber reinforcement and UV stabilizers to increase case strength by 40% while maintaining lightweight advantages. PP offers excellent chemical resistance against most acids, alkalis, and salt solutions.
One-piece injection molding eliminates seams and weak points, ensuring uniform structural strength. Wall thickness is precisely calculated to ensure protection while controlling weight. PP's excellent insulation properties make it ideal for electronic equipment transport, and it's food-grade safe, non-toxic and odorless.
IP67 Protection Rating Explained
International Protection Standard for comprehensive device safeguarding
Dust Protection — Level 6
Completely dust-tight, no dust ingress
