FIRO-CM is a dry and flexible insulating tape made of calcined mica
paper Muscovite ,a glass cloth and modified silicone resin .
According to the different reinforcing material, the products can
be divided into following ones:
S-CM-GS/FIRO-CMGS Glass Backed Calcined Muscovite Mica Tape
Note: Meaning of product code
S- CM: product serial number; CM: calcined Muscovite;
FIRO-CM is used for the insulation of flame resistant security
cables according to requirements IEC 331 or BS 6387 .Pyromania is
wound up around the bare or insulated wire and it provides a
protection barrier .The insulation must withstand at temperature up
to 1000℃ .Pyromania is not burning ,non toxic and it is resistant
for corrosion ,humidity and acids .
Length: 300m 500m 1000m 2000m .Traverse wound spools optional
Standard cores: 52mm 54mm 76mm 120mm
In dry environment at room temperature, the storage period is 3
One pack is usually at 50kg, sealed with plastic film and packed in
carton. The fumigation-free pallet shall be used when exporting.
Each pallet contains <1000KG, or protected by metal drum.
The technicians should select appropriate width mica tape based on
the wire sizes, winding tension, angles and wrapping speed, in case
of broken tape or missed space, to ensure the surface of the
insulated conductors after wrapping is smooth and flat, no mica
When winding small cross section wires, due to small coiling
radius, the mica falls off easily. The width of the mica tape is
small and the tensile strength is small, so the coiling tension and
speed shall be uniform, in case tape broken and mica powder fallen
Mica tape wrapping layers and lapping rate are different when the
material properties, specifications and models of the cables are
different, and shall be determined by the cable designer based on
the result of fire resistance test. According to IEC standard about
fire-resistant cable testing, we recommend wrapping layers are 2
and the lapping rate is not less than 50%, i.e. the wire is wrapped
by 4 layers of mica tapes.
