What does one mean by weathering and how is the film effected-indoors/outdoors by temperature, moisture etc.?
Weathering is what naturally occurs in the open environment but is as well a test method using UV radiation,temperature and moisture to study the degradation behavior of plastics.The major difference indoor and outdoor on the film would be the absence or presence of direct UV light, oxygen and higher changes in moisture and temperature which would accelerate or decelerate the process of degradation.(Also see question 18).
