Phasenwechselmaterial 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 Phasenwechselmaterial 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.
Tiefe Einführung
Phasenwechselmaterial (paraffins / salt hydrates / bio-waxes) is a family of grades whose density ~0.8–1.6 g/cm³, heat band designed 18–28 °C for buildings, and fire letter paraffin = combustible; salts vary.
Phasenwechselmaterial is sold as grades, not as a single substance. Chemistry paraffins / salt hydrates / bio-waxes, density ~0.8–1.6 g/cm³, heat band designed 18–28 °C for buildings.
This atlas treats Phasenwechselmaterial as a system: mill route, coatings, tests and the cavity it sits in.
Conductivity note: low-to-moderate; often needs fins or graphite. Insulation score 52/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: paraffin = combustible; salts vary. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: NASA / Telkes 1940s–70s; building PCM 2000s, United States / 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 48/100. Ask which scrap, which certificate, which year.
