Otto Bayer
Diisocyanate + diol → polyurethane at IG Farben / Bayer.
聚氨酯泡沫 did not arrive as a finished commodity. Otto Bayer 1937; fridge foam 1950s around Germany still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.
