I dont think you have the facts to say anything like that.Thats a ridiculous statement to make. And passing on the same things spit out all over the internet is just as bad. Just admit WE DONT HAVE ALL THE FACTS.I believe it fair to say that light or UV accelerates the process.
In the past year or two we have discovered Airbrighting in direct sunlight WHITENS plastic. And Anyone who has owned an old car knows how a bleaching effect cna happen to things inside thr car.
If UV exposure causes yellowing then why do all my UV lamps work so well at retrobrighting?
The only thing I can say with utmost certainty is HEAT yellows plastic. I have heat welded (hot air) some badly broken plastic and although it repaired it, at the same time it almost instantly became much more yellowed. The strangest thing was when I tried sanding some of this newly yellowed plastic The yellowing was so deep sanding wouldnt remove it.
So if you want to keep regurgitating what others say without any more understanding of the process you might as well start giving the CRT discharge disclaimer every post you make.. If you want to be a quacking duck.. might as well do it right.
