Does anyone have any expertise or experience with regard to UV stability in plastics; when the addition of a UV package is necessary for plastic components that will be used indoors under fluorescent lighting and on occasion - indirect sunlight?
I am having a problem in which products that have been in the field for less than 2 years under these conditions are exhibiting noticeable color shift. There are a number of factors that might be contributing to the color shift including possible reaction with chemical cleaners.
I’m mostly looking for experience and how other designers have made decisions with regard to UV stability in plastics.
I’m getting some help from compounders but the information is not really actionable and there are many variables. The simple answer seems to be to never, if possible, specify a material without a UV package.
