I. Introduction to performance:

Nanjing Yuwei New Material Co., Ltd.can provide super high temperature resistant special engineering plastic-polyimide profiles with temperature resistance grades above 260℃, 300℃ and 350℃ according to the specific needs of customers, such as bars, plates, pipes, injection molding and machined products. Polyimide PI has high and low temperature resistance (-269~400℃), high friction resistance, self-lubrication, high strength, high insulation, radiation resistance, corrosion resistance, Low thermal expansion coefficient, organic solvent resistance, self-extinguishing, non-toxic and other comprehensive properties. The long-term working temperature of some types of PI is above 350℃, and the short-term working temperature can reach 450℃. Is the engineering plastic with the best temperature resistance among engineering plastics at present. Its comprehensive performance is unmatched by other special engineering plastics, and it is praised as "an expert in solving problems" by the world. It is widely used in high-tech fields such as aviation, aerospace, machinery, electricity, atomic energy, microelectronics, thin film and liquid crystal display.


II. Application field:

After years of market cultivation, polyimide has been used as sealing materials, structural materials, heat insulation materials, friction materials and high-temperature coatings in aerospace, military industry, automobiles, compressors, large motors, pumps, tobacco machinery, textile machinery, Construction machinery, office machinery, electronic products, mold industry, etc. are widely used as high temperature-resistant, wear-resistant, self-lubricating or sealing parts, and have won high praise from users.


III. Product classification:

Polyimide is classified from the temperature resistance level:

1、NJSSPI-1003:The long-term working temperature is above 350℃ and the short-term working temperature can reach 450℃. It can be molded by hot pressing and cold pressing sintering, and can also be made into high-temperature adhesive.

2、NJSSPI-1006:the long-term working temperature is about 260℃, which can be used for hot molding, cold pressing sintering, injection molding and other molding processes, and can also be made into high-temperature adhesive for insulation, high-temperature coating and other fields.

3、NJSSPI-1007:The long-term working temperature is about 300℃,which can be used for hot molding, cold pressing sintering, injection molding and other molding processes, and can also be made into high-temperature adhesive for insulation, high-temperature coating and other fields.

4、NJSSPI-1008:The long-term working temperature is about 220℃, and the short-term working temperature can reach 300℃,which can be used for hot molding, cold pressing sintering, injection molding and other molding processes, and can also be made into high-temperature adhesive for insulation, high-temperature coating and other fields.
