냉장고와 건물의 저λ 유기 폼 — 단열은 뛰어나고, PIR·마감이 정직해야 화재가 된다.
다른 이름: PUR · PIR · rigid PU insulation
폴리우레탄폼 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 폴리우레탄폼 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.
깊이 읽기
폴리우레탄폼 (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.
폴리우레탄폼 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 폴리우레탄폼 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.
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 32/100. Ask which scrap, which certificate, which year.
