VESPEL Poyimide INSULATORS HOT NOZZLE

As a high-performance polymer, the processing of polyimide (PI) is critical to the full realization of its properties. Appropriate processing methods can ensure that polyimide has excellent insulating properties, high temperature stability and good mechanical properties. During processing, parameters such as temperature, pressure and time need to be strictly controlled to ensure the quality of the final product. At the same time, for different applications, also need to explore and optimize the corresponding processing technology, so as to give full play to the diverse characteristics of polyimide, to meet the application requirements of a variety of complex environments.

 

Polyimide, this organic polymer material, not only high temperature resistance, high insulation, but also has excellent mechanical properties. The processed parts are not only wear-resistant, but also heat-resistant and maintain high mechanical strength, so that they can also play a stable performance in the complex and changing working environment.

 

Polyimide (PI) materials play a key role in many fields due to their many excellent properties. Not only does it have excellent heat resistance and can be used for long periods of time at temperatures ranging from 300°C to 380°C, but it also exhibits low-temperature resistance and maintains its mechanical strength in ultra-low-temperature liquid nitrogen. In addition, polyimide's good mechanical properties, including high strength and high modulus, enable it to maintain excellent performance in harsh environments. It also has excellent electrical insulation, chemical resistance, radiation resistance, and good dielectric and insulating properties. The flame retardancy of polyimide is also quite excellent, as a self-extinguishing polymer, with a residual carbon rate of more than 50% after burning at high temperatures, making it an ideal heat retardant and flame retardant. What's more, some polyimides also have good biocompatibility, non-toxic and safe, can be used in tableware and medical equipment manufacturing. Although polyimide is insoluble and non-melting, and difficult to process, but through a special process, it can still be made into films, coatings, composites and other forms to meet the needs of different fields. These advantages make polyimide become an important material indispensable to aerospace, automotive, microelectronics and other high-tech fields.
