Polyimide film as a substrate, coated with special pressure sensitive adhesive, with good chemical resistance and wear resistance, the highest can withstand up to 320 ℃ temperature, flux, melting agent and detergent and other chemical substances have a certain anti-corrosion effect, use in high temperature and wear extreme environment can maintain excellent performance. It is designed for printed circuit board characters or barcode labels, because it can withstand the production of printed circuit board in the process of welding agents, melting agent, etc. erosion. At present, the thickness is mainly 25um, 50um two kinds. Common colors are black and white. High temperature resistant label stickers are widely used in many electronic products SMT and wave process, host board, corrosion products, mobile phones and lithium batteries and other products of high temperature labels.
