Thomas: Lego uses primarily Bayer Novodur (and apparently to some extent Bayer Lustran) for its bricks. The exact composition of the Novodur is of course, like the recipie for Coke, is top secret, but it is probably closest to Bayer Novodur P2M-V A (...) (23 years ago, 6-Mar-02, to lugnet.technic)

(...) My guess would be 109C may be more likely - I'd be surprised if they could mold it at 109F. I'm guessing my bad experience with the heater was well over 109F (they were quite close to it), and they didn't "flow" anywhere near enough that I'd (...) (23 years ago, 5-Mar-02, to lugnet.technic)
