True quality is revealed not just at the finish line, but throughout the entire process of extreme torture. Instead of only showing the final “Pass” result, the matrix below tracks the real-time performance evolution of Fortune Stone’s Flexible Stone under sustained, destructive environmental stress. This proves the material’s exceptional, linear stability and zero-compromise durability.
| Stress Test | Timeline / Cycle | Performance Evolution (Observed Changes) | Engineering Conclusion |
|---|---|---|---|
| 1500-Hour Weather Aging (Xenon Arc UV Exposure) | 600 Hours | • Grey Scale: 4-5 • Color Change Rating: 0 (No change) • Chalking Rating: 0 • Appearance: No cracking, swelling, or flaking | Outstanding Stability: At 600 hours, the material shows virtually zero degradation. |
| 1000 Hours | • Grey Scale: 4-5 • Color Change Rating: 0 (No change) • Chalking Rating: 0 • Appearance: No cracking, swelling, or flaking | Sustained Excellence: Performance remains identical to the 600-hour mark. | |
| 1500 Hours (Limit) | • Grey Scale: 4-5 • Color Change Rating: 0 (No change) • Chalking Rating: 2 (Slight chalk, washes off in rain) • Appearance: No cracking, swelling, or flaking | Ultimate Durability: Passes the ultimate torture test with zero color fade and zero structural failure. | |
| Extreme Freeze-Thaw Cycles (Thermal Shock: -18°C to 50°C) | Cycle 1 (18h water + 3h freeze + 3h dry) | • No powdering, crack, peeling or blistering. • No obvious change in color. | Instant Resilience: The material easily absorbs the initial expansion stress of freezing water. |
| Cycle 2 | • No powdering, crack, peeling or blistering. • No obvious change in color. | Unwavering Integrity: Structural integrity remains perfectly intact. | |
| Cycle 3 (Limit) | • No powdering, crack, peeling or blistering. • No obvious change in color. | Total Reliability: Proves the 200mm flexibility effectively prevents freeze-thaw shattering. |
