Aluminum Foil Adhesive Tape As one of the indispensable products in the electronics and electrical related industries, it has many excellent characteristics, and today, aluminum foil adhesive tape is used as an example to explain its three major characteristics.
1. Single and double-sided conductivity
Aluminum foil tape according to its conductive properties, divided into double-conducting aluminum and single-conducting two kinds. Aluminum foil is metal, itself has conductive properties, double-conductive is the use of conductive glue as a backing, resulting in a double-sided conductive effect; and single-conductive on the contrary, the use of non-conductive glue, only one side of the aluminum foil containing conductive. Its function is to eliminate electromagnetic interference, isolate electromagnetic wave harm to human body, avoid unwanted voltage and current affect product function.
Aluminum foil tape is often used when repairing LCD TVs and other household appliances, and when the repair involves touch switches, the use of this tape can enhance the conductivity of the touch switch. If the remote control buttons at home to lose conductivity, the effect of conductive adhesive is not very good, you can cut a small piece of paste on the reverse side of the button to enhance the conductivity.
2. Temperature and corrosion resistance
Because aluminum foil in the formation of the furnace has been processed at high temperatures, so aluminum foil tape has another main characteristic is temperature resistance. The temperature resistance of the normal type is usually 80 °, and the double-conductive type can even reach 120 °.
Corrosion resistance is achieved by waterproofing, anti-aging, non-curing, non-cracking, long-term non-movement, non-peeling and other conditions. There is also due to the role of aluminum foil reflecting ultraviolet radiation and its own unique characteristics of self-passivation in the air, so that the tape has excellent anti-ultraviolet function and prevent aging function, can play a long-lasting role in anti-corrosion insulation, will not be easy to produce peeling, delamination of the phenomenon.
3. Strong sealing
Aluminum foil tape has excellent barrier properties, moisture-proof and airtight. When there is wear and tear or cracks in the electrical lines at home, you can use it to wind and repair, which can play a certain sealing effect. And because of the superior insulating properties, it is more suitable for circuit repair.
