Strength band
fibroin tenacity high for a protein; still not aramid
Numbers below are bands used by working engineers, not live quotes. Tensile note: fibroin tenacity high for a protein; still not aramid.
Fire performance in this atlas is editorial. Real projects need the assembly report.
Механика
Stiffness
Modulus follows chemistry and orientation — not the marketing nickname.
Toughness
Crack growth, not peak stress, retires most real parts.
Fatigue / creep
Cyclic and time-dependent damage dominate certificates issued on static coupons.
Hardness / hand
Indentation, drape or compressive class — whichever the trade actually measures.
Тепло
Conductivity
low — Шёлк is not a substitute for a dedicated λ layer.
Service temperature
Melting / softening / decomposition band: degrades; no thermoplastic melt.
Expansion
Joints and clearances must follow the expansion class of Шёлк, not of steel-by-habit.
Thermal mass
Density ~1.34 g/cm³ sets how fast a section changes temperature.
Ageing of λ
Foams, VIPs and moist batts drift; quote aged values.
Электрика
Conductor or dielectric
Шёлк is generally a dielectric or semiconductor film, not building wire.
Static / EMI
Fillers and moisture change resistivity more than brochures admit.
Standards language
IACS, volume resistivity or dielectric strength — pick the quantity the job uses.
Огонь
Reaction to fire
Typical declared class: combustible protein. This is not a universal passport.
Resistance vs reaction
Euroclass is reaction. EI/R ratings are assemblies — boards, coats, cavities.
Melt-drip / char
Шёлк can burn or drip; do not treat it as A1 without a system test.
Smoke / toxicity
CO, HCN, HF or fibres — the species depend on chemistry. Name the test (ISO 5659, EN 45545, NFPA 1971).
If a salesperson quotes a single “safety score”, ask which standard, which thickness, which year.

Хлопок
Целлюлоза семенного волоска, одевшая промышленную революцию.
Итого 44 🐑Шерсть
Кератин с извитостью, держащий неподвижный воздух.
Итого 53 🎽Полиэстер
Господствующий полимер одежды: ПЭТ из бутылок, быстро сохнет, микроволокна.
Итого 49 🪢Нейлон
Полиамид Карозерса: чулки, корд, верёвка, капающий расплав в огне.
Итого 48 🦺Арамид
Ароматический полиамид: бронепакеты, горячая фильтрация, замена асбеста.
