Silicone in 1990s: LSR injection
Read the condition on Silicone before the nickname. Year 1990s, line “LSR injection,” figure 50. Origin story: Kipping / Rochow 1940s (United Kingdom / US). A material is what it is made of, the condition it survives, and where it goes afterward. Silicone under “LSR injection” in 1990s should say which, with 50 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 Silicone 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.
Silicone ([R2SiO]n) is a family of grades whose density ~1.1–1.5 g/cm³, heat band elastomer; resins cure, and fire letter often high LOI vs organic rubbers. Silicone is sold as grades, not as a single substance. Chemistry [R2SiO]n, density ~1.1–1.5 g/cm³, heat band elastomer; resins cure.
This atlas treats Silicone as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: ~0.2 W/m·K; filled greases conduct. Insulation score 42/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: often high LOI vs organic rubbers. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
The label keeps Silicone, 1990s, and 50. “LSR injection” is the condition on the figure.1990s
