i have some small ABS plastic parts that i wish to "discolor" or in other words "yellow" chemically and want to know how this might be achieved.
The type of yellowing i am after is the kind you frequently see with old gray computer keyboards or mouses that have yellowed over time. Or if plastic has been left outside for a while and has yellowed from sun damage. I want a moderate version of that.
ironically, I know how to REVERSE yellowing for my parts, by immersing them in a bowl of Hydrogen Peroxide and leaving outside in direct sunlight for hours or days, and they become white as new, all discoloration is reversed quickly.
But now i want to know how to speed up the yellowing process into something that i can consistently do, in bulk, in a relatively short time frame. There must be a way to do this chemically.
Looking forward to your suggestions
