La mousse organique à faible λ des frigos et bâtiments. Le feu exige PIR et parements honnêtes.
Aussi appelé: PUR · PIR · rigid PU insulation
Mousse de polyuréthane is one of 32 materials in this atlas, grouped under thermal: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.
Scores compare Mousse de polyuréthane with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
Introduction approfondie
Mousse de polyuréthane (R-NH-COO-R′ network + blowing agent) is a family of grades whose density 30–60 kg/m³ rigid boards, heat band pyrolyses; does not melt cleanly, and fire letter typically E–B with facers; not A1.
Mousse de polyuréthane is sold as grades, not as a single substance. Chemistry R-NH-COO-R′ network + blowing agent, density 30–60 kg/m³ rigid boards, heat band pyrolyses; does not melt cleanly.
This atlas treats Mousse de polyuréthane as a system: mill route, coatings, tests and the cavity it sits in.
Conductivity note: λ ~0.022–0.028 W/m·K (aged PIR boards, bands). Insulation score 88/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: typically E–B with facers; not A1. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: Otto Bayer 1937; fridge foam 1950s, Germany. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: mineral-wool.

Circularity mark 32/100. Ask which scrap, which certificate, which year.
