 | | ABS... but which one? —Pedro Silva
|
| | | Hi all, Some years ago I recall seeing an article about LEGO, where there was a small image of ABS granules being fed to a moulding machine. Back then I did not care too much about it, but now it appeared interesting enough to investigate... So I (...) (22 years ago, 2-Jan-03, to lugnet.general)

| | | | | (...) I don't know any of the technical specs of bricks now or then, but let me share my feelings on the subject. I know that by comparing my old childhood bricks (20 - 25 years old) to bricks I've bought in the last 5 years there is a distinct (...) (22 years ago, 3-Jan-03, to lugnet.general)

| | | | | | (...) Thanks for posting your experience, Allan. What I'm curious now is knowing how the more recent bricks will be in 25 years. If they look "less good" than the previous at this point in time, perhaps in 25 years they will have become *wrecks*. (...) (22 years ago, 3-Jan-03, to lugnet.general)

What I meant was: brand new bricks bought 10 years ago (before the claimed ABS change), and brand new bricks bought *now* click different from each other. In fact, the more recent ones don't (...)

| | | | | | | I have bought some lately (bulk) that seem to not even want to stay together. Out of a stack of 25 2x4 bricks. I usually find 1 or 2 that fall apart from its proposed partner. I always just find another spot for them or take them out of the model. (...) (22 years ago, 3-Jan-03, to lugnet.general)

| | | | Pedro: Your assumptions are absolutely correct. Most of Lego's plastic is a special (top secret) version of Bayer Novodur. Lego also uses a version of Lustran and, more recently, a version of Makrolon. If you spend enough time on the Bayer site they (...) (22 years ago, 3-Jan-03, to lugnet.general)

I would have taken longer to find out LEGO references in Bayer's website, mainly because I were not *expecting* there would be any... turns out they are proud of their role as suppliers - and they have reasons for (...)
