High temperature resistant labels are one of the widely used special label technologies for comparison. The application service industry of high temperature resistant labels is also very extensive. The application of various research on high temperature labels is also different. Overall, they are widely used in the automotive finance industry, e-commerce business, production enterprise manufacturing industry, and steel company industry management. For example, special labels with high temperature resistance are required for automotive engine labels, automotive compressor labels, automotive starter motor labels, PCB motherboard labels, steel product labels, aviation labels, etc., but the degree of high temperature resistance also varies. What are the characteristics of high-temperature resistant labels besides being fearless of high temperatures?
The label is made of high-temperature polyimide film as the substrate, coated with special pressure-sensitive adhesive with good chemical resistance and wear resistance. The maximum resistance temperature is up to 320 ℃, and the flux and melting agent chemical cleaner have certain corrosion resistance. It maintains excellent performance under extreme environments of high temperature use and wear.
In the development of the e-commerce industry, it is designed specifically for labeling printed circuit boards with characters or barcodes, as it can withstand the erosion of soldering agents, melting agents, etc. that are required in the management of printed circuit board work processes through social production technology. At present, there are mainly two types of thicknesses: 25um and 50um. The commonly used colors are black and white. High temperature resistant label stickers are widely used in SMT and peak processing of electronic information products, motherboards, main corrosion products, mobile phones, lithium batteries and other products in enterprises.
High temperature labels have three main components: a base material, adhesive, and substrate.
Substrate coated with polyimide film 25um (or 50um)
The absence of polyimide coating does not meet the performance requirements to better meet the coating performance required for barcode printing and color and gloss materials.
Adhesives: Nowadays, adhesives can generally be divided into the following three categories: rubber, acrylic, and silicone. Rubber adhesives have low cost, poor temperature and chemical resistance, and outstanding aging resistance. Silicone adhesives have significantly superior performance, but the problem is that they are expensive. Acrylic adhesives have a temperature resistance of about 200 degrees, good chemical and oxidation resistance, and reasonable prices. Currently, some enterprise brands use acrylic materials for 90% of their adhesive tapes. The high-temperature environment label data adopts a permanent acrylic pressure-sensitive adhesive.
Substrate: glossy release paper, white copper release paper, silicon yellow release paper, PET release film
High temperature resistant labels are widely used in industries such as automotive engines, electronic information manufacturing, aluminum, and aerospace in China
Using PCB labels and electronic circuit surface mounting technology, it can perform thermal transfer printing and display the best and first-class reading rate. Even if the label board is directly removed from the environment with solder paste, the label can still be stain resistant. If the label is preheated, it can further resist various chemicals such as welding agents, melting agents, and cleaning agents, as well as extreme harsh environments such as high temperature and wear, ensuring good performance in various extremely harsh and demanding application environments.
