Phase-change material in 2020s: Bio-based waxes
hydrates / bio-waxes) is a family of grades whose density ~0.8–1.6 g/cm³, heat band designed 18–28 °C for buil Scores compare Phase-change material with the rest of the atlas on strength, heat, fire behaviour, insulation, Read the condition on Phase-change material before the nickname. Year 2020s, line “Bio-based waxes,” figure 21. paraffins / salt hydrates / bio-waxes A material is what it is made of, the condition it survives, and where it goes afterward. Phase-change material under “Bio-based waxes” in 2020s should say which, with 21 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.
Scores compare Phase-change material 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.
Phase-change material (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. Phase-change material 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 Phase-change material 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.
The label keeps Phase-change material, 2020s, and 21. “Bio-based waxes” is the condition on the figure.2020s
