While ABS may be the most well-known plastic used by LEGO, they actually use a wide variety of plastics. Here’s an example of all the kinds of plastic used by LEGO provided by BrickNerd guest contributor Ryan Howerter.
Neat! This is a very comprehensive writeup! I found this part particularly interesting:
Modern Technic bricks with pins, such as 42929, are dual-molded so the brick part is ABS and the pin is PA (this is why they show up in BrickSet as “multicombination”, even though it’s the same color throughout).
I didn’t know dual-molding was possible, and I’ve never noticed a visible seam or difference in colouration.
