[Product Description]: Spreading Wing Aluminum Foil Mylar, also known as Butterfly Wing Aluminum Foil Mylar, is a second precision composite of a sliced aluminum foil Mylar strip and a wider Mylar film.

[Application]: Mainly used for interference shielding that requires external insulation, and the thin film extending on the side provides reliable insulation sealing effect. Used for interference shielding of multi conductor wires such as twisted pair cables, composite wires, etc., such as control wires, computer wires, and signal transmission wires, it is an essential material for high-frequency wires such as DVI, HDMI, DP, RGB, etc.

1、 Main technical indicators:

2、 Color: Common colors are blue and silver, and can also be made into red, green, gold, etc. as needed.

3、 Application: Mainly used as EMI shielding packaging material for high-frequency communication, electronic and other wires and cables. In high-frequency cables such as DVI, HDMI, DP, etc., due to special requirements for version and process, the spread wing aluminum foil Mylar tape is designated for use by the association. It is equivalent to simultaneously wrapping ordinary aluminum foil and polyester Mylar tape, which not only reduces the number of operating procedures for the first mate delivery, but also allows for one-time wrapping and forming, and reduces the defect rate by 20%.

4、 Electrical characteristics: mainly used for anti electromagnetic interference, usually in the range of 1-100MHz, with a shielding attenuation of about 70dB, it can be achieved using wingless aluminum foil Mylar.

5、 Cutting and packaging: The minimum cutting width is 6+8mm, and the inner hole size is 52mm or 76mm; The maximum outer diameter of the winding is 800mm, packaged in cardboard boxes.
