Pre-insulated Copper Foil - Copper Foil Coated with PET Film for Cable Shielding

    Thickness: 0.023mm - 0.050mm


    Inner Diameter: 76mm


    Length: 100m, 200m


    Insulated Material: PET, PEN, Nomex, Kapton

Specifications of Pre-insulated Copper Foil:

Copper foil tape can be divided into single and double conductive copper foil:

Single conductive copper foil tape refers to one side having an overlying non-conductive adhesive surface, and bare on the other side, so it can conduct electricity; so it is said that it is single-sided conductive copper foil

Double-sided conductive copper foil refers to copper foil that also has an adhesive coating, but this adhesive coating is also conductive, so it is called double-sided conductive copper foil.

1) Standard: Regard of different insulated coating material, the thermal endurance class are B, F, H in according to RoHS-2002/95/EC

2) Delivery State: With 100 and 200m copper foil round on the inner diameter of 76mm coil core

3) Storage Condition: No more than 6 months, under the dry and cool environment condition about 20℃

4) Technical Properties:

Available on pads and spool.

Performance of Copper Foil:

One side is copper, other side has insulating paper; In the middle is an imported pressure-sensitibe acrylic adhesive. Copper foil had strong adhesion and elongation, It is mainly due to copper foil’s excellent electrical properties that during processing it can have a good conductive effect; Secondly we use adhesive coated nickel to shield electromagnetic interference on the surface of copper foil.


Advantages of Pre-insulated Copper Foil:

1) Copper foil purity is higher than 99.95%

2) The function is to eliminate electromagnetic interference (EMI)

3) Electrostatic charge will be grounded, strongly bonded, good conductive propertied.

4) Reduces the necessary cross section of copper because of optimal shape in comparison to round wires

5) Ease of getting admittance for a winding construction due to the optimal safety

6) More reliable due to reduction of vibration, better thermal conductivity 

7) Prevents danger of short circuit between primary and secondary windings

Characteristics of Copper Foil: 



1) Can be used below 100°C

2) Elongation is at about 5%, but can be changed in accordance with customer specifications

3) Should be stored in a room temperature and can be stored for less than one year

4) When in use, keep adhesive side clean of unwanted particles, and avoid repeated use
