01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become 상변화소재.
Making 상변화소재 is a chain: feedstock, conversion (NASA / Telkes 1940s–70s; building PCM 2000s), forming, heat, finish, install.
Skip a step and the properties chapter is describing a different object.
공정 단계
02 Conversion
NASA / Telkes 1940s–70s; building PCM 2000s
03 Forming
Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
04 Heat / cure
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
05 Finish
Coatings, sizings, facers, galvanizing, anodising, painting.
06 Install
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
경로
Primary
Virgin route around United States / Germany.
Recycled / secondary
Recycling exists but quality or energy often disappoints.
Specialty
High-spec grades leave the commodity mill.
Site-applied
Coatings, sprays, casts — the factory is sometimes a jobsite.

한계
Envelope
Melting/softening designed 18–28 °C for buildings; conductivity low-to-moderate; often needs fins or graphite.
Environment
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills 상변화소재.
Code
Fire class paraffin = combustible; salts vary is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
