SEBS (Styrene-Ethylene-Butylene-Styrene)
SEBS is a thermoplastic that behaves like rubber, without needing vulcanization. LEGO uses this for tires — and, famously, LEGO makes most of the tires in the world, by number if not by mass! I believe that LEGO used to make their tires out of styrene-butadiene-styrene (SBS), which is less stable and heat-resistant than SEBS.
the amount of work it took to get these tires looking so dust-free 😭
