PI label

PI label (polyimide label) is a special labeling material made from a polyimide base material. Polyimide is a high-performance engineering plastic with excellent heat resistance, mechanical strength and good electrical insulation properties. Due to these properties, PI film is widely used for labeling needs that are subjected to extreme conditions.

Features

1. Extremely high temperature resistance: PI films can maintain stable performance over a wide temperature range of -200°C to +400°C, making them ideal for product marking in high temperature environments.
2. excellent chemical stability: it has good resistance to most solvents, acids, alkalis and other chemicals, and is not easily corroded or dissolved.
3. good dimensional stability: even after prolonged exposure to high temperatures, it can maintain its original shape and size without deformation.
4. excellent abrasion resistance: the surface is smooth and hard, can effectively resist the friction damage in daily use.
5. excellent electrical insulation properties: suitable for marking the internal parts of electronic equipment, will not affect the normal operation of the circuit.
6. Good printing suitability: support a variety of printing methods, including thermal transfer printing, laser printing, etc., can clearly present the text and pattern information.

Application

1. Electronic products: such as circuit boards, semiconductor chip packages, etc., using its high temperature resistance and good insulation to protect sensitive components and provide the necessary information labeling.
2. automotive industry: engine compartment parts labeling, the material is required to be able to be used in a high-temperature environment for a long time without failure.
3. Aerospace: For marking internal and external components of spacecraft, PI films are ideal given the extreme temperature variations and other harsh conditions in the space environment.
4. medical devices: some medical devices may need to be sterilized at high temperatures, and the labels used in this process must be able to withstand the appropriate temperatures without damage.
5. food packaging: although not common, PI films are also used as a substrate for labels in specific situations (e.g. microwave heating instruction labels).
