Environmental Adaptability
Definition
Maintaining stable performance across different temperature and humidity conditions.
Historical Background
1980s: environmental simulation testing drove weather-resistant formulation development.
Example
Tape must work at -30C in the north and +40C in the south. Like climate adaptability.
Formula
Environmental Adaptation Index = Extreme Performance / Normal Performance x 100%
Core Concepts
Performance stability under varying temperature, humidity, and UV.
Extended Applications
Indoor: 10-30C, 40-60%RH; outdoor: -20-60C, 20-90%RH; extreme: -40-80C, 10-95%RH; special: -60-200C, vacuum-high pressure.
