High temperature resistant polyimide adhesive material
High temperature resistant barcode label is an opaque polyimide (high temperature resistant) label with permanent acrylic pressure-sensitive adhesive and a white surface layer suitable for heat transfer printing. It is designed to meet the high temperature requirements of reflow soldering (260 ℃) and wave soldering (350 ℃) environments, and is specifically designed for character or barcode identification on printed circuit boards or related electronic components. In addition, the labels are designed to resist corrosive fluxes and multiple rounds of cleaning commonly used in circuit board applications, making them ideal materials that can withstand the erosion of various soldering agents, melting agents, and cleaning agents encountered in the production process of circuit boards
Features
There are two types of substrates: PI and PET UL94 VTM-0&VTM-1 Fire Rating Certification (Flame Retardant)
Compliant with FAR smoke and toxic gas standards
Compliant with BSS 7238& 7239 standard
High temperature resistance, chemical resistance
Compliant with REACH; And RoHS standard, halogen-free
Purpose
Suitable for SMT surface mount manufacturing process of PCB circuit boards, it is a special label for printed circuit board (PCB) identification (commonly used for temperature resistance of 260 ℃ for 6 minutes). After passing through the furnace, it does not bubble, curl, glue, yellow, or be easily corroded by various chemical substances in the flux
Nylon cloth adhesive material
Nylon cloth is a type of polyamide nylon cloth label with permanent acrylic pressure-sensitive adhesive and suitable for heat transfer printing and needle punching surface coating. It is mainly used for long-term identification purposes such as liquid nitrogen storage, laboratory test tubes, cables, etc. Nylon cloth labels have good wrapping properties, do not stretch feet, strong adhesion, good weather resistance, and can withstand harsh working environments such as high and low temperatures
Advantages of Nylon Fabric Material:
1. Suitable for different environments, including extremely low temperature environments with rapid cooling, high-temperature sterilization processes, and sterilization processes< br /> 2. With the design concept of non-toxic, harmless and environmentally friendly, it is a non-toxic product in medical and dust-free environments, with excellent printing and writing characteristics, and can be widely used in low-temperature environments such as biomedical< br /> 3. First class reading rate and superior chemical and wear resistance, with a width of 10mm capable of printing 15 digit barcodes and achieving 100% reading rate
4. Super low temperature resistance, even in liquid nitrogen environment of -196 ℃, the label can still be firmly attached to the wall of the freezer and maintained for a long time< br /> 5. Can be used for cable identification

Laser etched adhesive material
Laser etched label paper is a two-layer film used for the production of labels in laser marking equipment. By special production techniques, the black surface and white bottom form a unified whole. The material is halogen-free and resistant to chemical substances, temperature and other environmental influences. It is coated with high-performance acrylic adhesive, which has good initial adhesion and high final adhesion even on low-energy surface energy surfaces such as polypropylene. Laser label paper can also be used for identifying evidence based on specific application scenarios. Usually, once the label is attached to a surface and removed, it will be damaged and comply with UL/CSA standards
Laser can etch the top layer of double-layer materials to form a certain pattern. The same laser also allows labels to be semi perforated to specific sizes, increasing flexibility to manufacture various durable labels
