How do Silicone Rubber insulated cables compare to Mica-wrapped cables?

Silicone Rubber is an alternative to Mica tape for fire resistance.

Mechanism: When silicone burns, it leaves behind a non-conductive “ash” (silica) that maintains insulation.

Application: These are highly flexible and easier to strip/terminate than Mica-wrapped cables, making them popular for flexible fire alarm wiring in restricted spaces.
