Quick answers

Is Silicone non-combustible?

Declared reaction class in this atlas: often high LOI vs organic rubbers. Assemblies still need resistance tests.

Does Silicone insulate?

Thermal mark 42/100 versus the atlas. Conductivity note: ~0.2 W/m·K; filled greases conduct.

What is the density band?

~1.1–1.5 g/cm³

How is it made?

Origin story: Kipping / Rochow 1940s (United Kingdom / US).

Can it be recycled?

Circularity mark 40/100 — editorial, route-specific.

Typical melting or failure heat?

elastomer; resins cure

heat 80 · fire 62

Silicone did not arrive as a finished commodity. Kipping / Rochow 1940s around United Kingdom / US still explains who makes it and which tests it sits in.

Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.

Timeline

1901–44Kipping

Frederic Kipping named silicones, thought them useless oils.

1940Rochow–Müller

Direct process: CH3Cl + Si → methylchlorosilanes.

WWIIIgnition sealing

Military need funded Dow Corning and GE.

1943Dow Corning

Joint venture industrialised fluids and rubbers.

1960sMedical tubing

Physiology liked the inertness — later controversy on implants.

1970sRTV sealants

Construction joints.

1990sLSR injection

Liquid silicone rubber for baby and auto.

2000sLED encapsulants

Optical silicones.

2010sImplant litigation hangover

Regulatory caution, not a chemistry rewrite.

2020sEV gap fillers

Thermal interface silicones in battery packs.
