Polyimide (PI) Products - Sheets, Rods, and Tubes

Polyimide (PI) shows excellent temperature stability, remains intact under liquid helium at -269°C. Its thermal decomposition temperature usually exceeds 500°C, and some systems can even reach over 600°C, making it one of the most thermally stable specialty engineering plastics known. In addition, PI also has excellent mechanical properties, resistance to organic solvents, radiation, aging, and flame retardant and self-extinguishing characteristics. According to different product forms, PI materials can be made into films, fibers, thermosetting resins, photosensitive adhesives, slurries, separation membranes or diaphragms, aerogels, foams and other forms, which are widely used in electronics, aerospace, mechanical and electrical engineering, nuclear industry and other fields.

 

Core Characteristics

 

Polyimide is known as the “golden polymer material”, its outstanding performance includes:

 

High temperature resistance: long-term use of temperature range -200 ~ 300 ° C, short-term resistance of more than 400 ° C, some varieties of non-significant melting point.

 

Electrical insulation: dielectric constant of 4.0 at 103 Hz, dielectric loss of only 0.004 ~ 0.007, F to H-class insulation materials.

 

Mechanical strength: the tensile strength of unfilled plastic is more than 100MPa, both self-extinguishing and low smoke rate.

 

Chemical stability: irradiation resistance, abrasion resistance, corrosion resistance, adapt to extreme environments.
