🌡️Propiedades medidas

Fibra cerámica · Fibras refractarias a 1000–1400 °C: hornos, juntas, y la cautela respirable que AES intenta aliviar.

Numbers below are bands used by working engineers, not live quotes. Tensile note: blankets tear; modules are folded and anchored.

Fire performance in this atlas is editorial. Real projects need the assembly report.

Mecánico

Strength band

blankets tear; modules are folded and anchored

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.

Térmico

Conductivity

λ rises with T; still far below brick — Fibra cerámica is used as insulation.

Service temperature

Melting / softening / decomposition band: classification T often 1260–1400 °C.

Expansion

Joints and clearances must follow the expansion class of Fibra cerámica, not of steel-by-habit.

Thermal mass

Density 64–192 kg/m³ blankets sets how fast a section changes temperature.

Ageing of λ

Foams, VIPs and moist batts drift; quote aged values.

Eléctrico

Conductor or dielectric

Fibra cerámica 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.

Fuego

Reaction to fire

Typical declared class: A1. This is not a universal passport.

Resistance vs reaction

Euroclass is reaction. EI/R ratings are assemblies — boards, coats, cavities.

Melt-drip / char

Fibra cerámica tends to char or stay inorganic rather than melt-drip like commodity olefins.

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.
