FIRO-S consist of the most heat resistant Synthetic mica paper
bonded to an electrical grade glass cloth or film as the supporting
fabric ,impregnated with a specially selected high temperature
resistant silicone elastomer.
According to the different reinforcing material, the products can
be divided into following ones:
S-synthetic-GS/FIRO-SGS Glass Backed Synthetic Mica Tape
Note: Meaning of product code
S-synthetic :product serial number; S: Synthetic mica; GS:
Single-sided fiberglass tape;
The unique magnesium containing Synthetic mineral renders FIRO-P
mica tape the best flame-resisting characteristics .The silicone
elastomer ,when exposed to a flame ,gradually turns into inorganic
silicon dioxide by oxidative pyrolysis which ,itself , in
conjunction with the Synthetic ,offers outstanding electrical
insulation properties at elevated temperatures .
FIRO-S mica tape are free of halogens and toxic gases .Due to the
very high flexibility ,these tapes can be easily applied with high
speed standard taping equipment .
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.
