Phase-change material in 1990s: Microencapsulated paraffin — Section 1093: Microencapsulated paraffin
Atlas note 1093 on Phase-change material defines the operating range of 21 when “Microencapsulated paraffin” applies. Crack growth, not peak stress, retires most real parts. Keep Phase-change material with “Microencapsulated paraffin” and 21 from 1990s. Cyclic and time-dependent damage dominate certificates issued on static coupons.
Latent-heat packets that flatten temperature swings — not a substitute for λ insulation, a complement. Phase-change material 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. When reading the “Microencapsulated paraffin” stage inside the Phase-change material atlas entry, recording both the reference period and the operating boundary around figure 21 prevents common misinterpretations in real-world decisions.
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.
“Microencapsulated paraffin” for Phase-change material in 1990s carries 21. Praise without that figure is not a property. Keep Phase-change material with “Microencapsulated paraffin” and 21 from 1990s. 211990s

Interactive Scenario & Decision Matrix
Select your current objective to inspect the recommended benchmark, threshold, and verification path.
Keep heat resistance {heat}.
Briefing 11 for Aerogel aligns condition “Kistler” with reference value 0 on the ground.
Aerogel: 0 (1931)Keep the thermal line {therm0}.
Reading 12 of Aerogel uses “Lab curiosities” and figure 80 as a checkable baseline.
Aerogel: 80 (1960s)Use {therm0} only if it agrees with score {heat}. If they conflict, do not pick a product from this page.
Atlas note 13 on Aerogel defines the operating range of 0 when “NASA Stardust” applies.
Aerogel: 0 (1990s)Reading 4 of Aerogel uses “Aspen Aerogels” and figure 0 as a checkable baseline.
Dossier 14 for Aerogel links case “Aspen Aerogels” directly to metric 0 (1998).

5-Step Execution & Verification Playbook
- Read the fire-performance mark — Fire on this hub is {fire}/100 — teaching comparison among atlas materials.
- Read the insulation mark — Insulation is {insul}/100 — heat-flow story, not the same question as flame.
- Sit one published fact beside them — Quick fact on file: {fact0}.
- Sustainability is not a fire skip — A high sustainability mark does not replace fire protection in a real assembly.
- Not a building-code rating — Named tests, thickness and build-up still decide compliance — this page is literacy only.
Myth vs. Evidence Fact-Check
Is the fire-performance score a building-code rating?
No. It is an editorial 0–100 teaching mark among materials in this atlas. A real wall or garment needs a named product test, thickness and assembly. This page is not a lab stamp.
When should I read insulation instead of fire?
Use the insulation pick when the question is heat flow — lining, loft, or a cold-bridge — and the fire pick when the question is how the same material behaves in flame. Both numbers already sit on this hub; they answer different jobs.
Does a high sustainability score mean I can skip fire protection?
No. Sustainability here is a relative atlas mark (growth, reuse, embodied story). Bamboo and timber can still char like wood. Fire protection stays a separate specification.
Why is bamboo missing in some languages?
A language URL is published only when the seven chapters are real prose in that language. Bamboo exists in English, Korean, Japanese, Chinese and Spanish. French, German, Portuguese and Russian stay withheld — earlier machine drafts leaked English, so those URLs are not opened.
