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:
R-5461-S-GS/FIRO-SGS Glass Backed Synthetic Mica Tape
Note: Meaning of product code
R-5461:Rongtai 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 .
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 year.
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 falling off.
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 off.
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.
