Polyimide is a high-performance polymer known for its excellent thermal stability, mechanical strength, electrical properties, and chemical resistance. Due to these outstanding characteristics, polyimide is used in a wide range of demanding applications across various industries. Here are the primary uses of polyimide:
1. Semiconductor Industry:
In semiconductor manufacturing, PI materials are widely used in the electronics industry, especially in semiconductor production lines, involving chip lithography, transfer, and testing.For example:IC test Socket,Suction cup, Suction pen head,Wafer pressure ring,etc
2. Aerospace and Aviation
Thermal Insulation: Polyimide materials have extremely high temperature resistance, excellent weather resistance, friction resistance, radiation resistance, plasma resistance, thermal insulation, excellent dielectric properties and relatively good molding process. They can be used to make rocket fairings, missile shells, space station structures, key components of aircraft engines, oil-free transmission bearings and bearing sleeves for military equipment and vehicles, etc., and play a very important role in the military field.
3. Automotive Industry
Engine Compartment Parts: Polyimide is used in automotive parts that operate under high temperatures, such as components in the engine compartment, because of its high thermal stability and resistance to oils and fuels.The application of wear-resistant and high-temperature resistant special materials such as automobile brake sensor terminals, gearbox wear-resistant gaskets, thrust washers, glass lifting buckles, etc. can greatly improve vehicle safety and performance.
4. Industrial and Mechanical Applications
Bearings and Bushings: Polyimide resins are used in the production of self-lubricating bearings and bushings, which are employed in various industrial applications. These parts can withstand high temperatures and wear, making them ideal for use in machines, engines, and conveyor systems.
Gaskets and Seals: PI Engineering Plastics is also used in the production of high-performance gaskets and seals in demanding environments, such as high-pressure systems and machinery.
5. Hot Runner
The heat-insulating cap (color-changing sleeve) is a workpiece between the nozzle tip and the mold gate (without plastic coating) instead of the heat-insulating plastic layer. It reduces the yellowing/discoloration of plastic in the dead corner due to long-term high temperature. It is also suitable for producing white plastic products with good aesthetic effects. When injecting color-changing plastic products, it can shorten the color-changing time and improve the efficiency of the hot runner system.
6. Glass Industry
The thermal conductivity is much lower than that of traditional graphite accessories, which can effectively reduce or eliminate the inspection times and micro cracks of glass containers, reduce the scrap rate and improve productivity. The thermal conductivity is much lower than that of traditional graphite accessories, which can effectively reduce or eliminate the number of inspections and micro-cracks of glass containers, reduce the scrap rate and improve productivity. The service life of PI parts is several times that of graphite parts. These features can effectively improve production efficiency.
7. Plasma cutting
The polyimide swirl ring can maintain stable performance in high temperature environments. Generally speaking, it can withstand temperatures up to 300-400℃ and has high strength and hardness. The polyimide swirl ring can withstand a certain degree of mechanical pressure and impact. Its tensile strength can reach about 100-200MPa, which prevents it from being easily deformed or damaged when subjected to external forces. At the same time, it also has good wear resistance, and can effectively resist wear and extend its service life when it comes into contact with other objects and produces relative motion. The polyimide material itself has a certain flexibility and can effectively disperse stress, which gives it good fatigue resistance and extends its service life in a dynamic working environment. Due to its material properties and precise manufacturing process, the polyimide swirl ring can effectively control the eddy current.
Polyimide is a versatile, high-performance polymer that finds applications in industries where extreme conditions such as high temperatures, mechanical stress, and electrical insulation are a concern. From aerospace to electronics, automotive to medical devices, polyimide’s unique combination of properties makes it indispensable in a variety of critical and advanced technologies.
