Why does rubber turn green?
Re: Hard rubber discoloration
Hard rubber oxidizes and discolors – particularly if it is exposed to lots of UV. Different compositions of hard rubber oxidize more than others, so some pieces will turn more quickly than others.
Why do F1 cars pick up rubber?
The point of this exercise is to allow the hot tires on their car, which are sticky when they are quite hot from race laps, to come into contact with, and pick up the chunks of rubber (given the name “clag” by previous race announcer and ex-F1 driver David Hobbs) worn off of tires from all of the cars running during …
