Otto Bayer
Diisocyanate + diol → polyurethane at IG Farben / Bayer.
폴리우레탄폼 · 냉장고와 건물의 저λ 유기 폼 — 단열은 뛰어나고, PIR·마감이 정직해야 화재가 된다.
폴리우레탄폼 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.
Diisocyanate + diol → polyurethane at IG Farben / Bayer.
Comfort market first.
Replaced cork and glass wool in appliances.
US commercial roofs.
CFC blowers began to exit.
Isocyanurate index for better fire indices.
Climate GWP problem replaced ozone problem.
Lower-GWP blowing agents.
Insulation combustibility became a public brief — chemistry and system both.
Formulators juggle λ, fire and climate.

Knowing this timeline is how to read a mill certificate without treating 폴리우레탄폼 as timeless.
