Weathering
Posted on 01/01/2019 Category:
A broad term encompassing exposure of plastic and rubber materials to solar or ultraviolet light, temperature, oxygen, salt water, biological attack, humidity, rain, snow, wind, and air-borne biological and chemical agents. Resistance to weathering is not easy to define, but typically glazing seals for architectural installations will demand a 25 year life. Accelerated testing can measure the change in typical physical properties, but devising fully representative testing is difficult. See also Perishing.
