Firstly polymide film is treated with special base coating. It is then coated with organic silicon series or acrylic acid ester series pressuresensitive adhesive. - It can withstand high voltage resistance, high temperature resistance and solvent resistance. Usage: This tape has mainly been utilized in the gold finger protection during the circuit plate (PCB) over wave soldering, transformer insulation, binding lithium cell polar ear fixing and on other occasions that need heat-resistance.
