High Temperature Resistant Label Sticker With Polyimide Film As Base Material



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, commonly used color is black and white.
