Polyimide plastics contain long chains of imide monomers that impart key attributes like:
These make polyimide plastics ideal for applications that require materials that can withstand extreme temperatures, caustic chemicals, and wear and friction over time. Major PI plastic types include P84, Kapton, Vespel, and others.
The aerospace industry takes advantage of many polyimide plastic properties. PI plastics have high heat resistance exceeding 572°F (300°C), making them suitable for aerospace wiring insulation and other components.
Aerospace grade PI plastic films are used to insulate wiring due to its high dielectric strength. This wire insulation does not melt or burn easily and protects aircraft electrical systems at altitudes up to 100,000 feet.
PI plastic's thermal stability allows it to be formed into bearing cages, bushings, and washers within jet engines. The high heat tolerance prevents failure of engine parts at extreme temperatures.

With good insulation properties and heat resistance, PI plastics serve well in electronics applications including:
Flexible printed circuits frequently use polyimide plastic film substrates. PI plastic films provide flexibility along with thermal and chemical stability for long life.
PI plastic films or tubing insulate wires and cables in consumer electronics and industrial equipment. The high dielectric strength resists electrical breakdown.
Glass fiber reinforced PI laminates are used to fabricate printed circuit boards. The dimensionally stable PI plastic boards withstand soldering temperatures.
Polyimide parts withstand friction, wear, and high heat in automotive and machinery environments:
PI plastic bushings, washers, and thrust washers maintain dimensional integrity even at temperatures over 500°F (260°C). This makes them well-suited for automotive engines.
PI plastic wear pads protect equipment while resisting abrasion. Used in escalators, conveyors, and other machinery. The self-lubricating nature reduces maintenance.
Wire insulation made of polyimide withstands the high heat conditions within electric motors. It helps prevent short circuits in generator windings too.
PI plastics meet the demanding requirements of medical device applications:
The biocompatible and chemically inert nature of polyimide allows its use in implants and prosthetics that reside inside the human body. Devices include skull plates and intraocular lenses.
Thin-walled PI plastic tubing forms the lumens of catheters for angioplasty and other procedures. It withstands repeated autoclave sterilization cycles.
Wear-resistant PI plastic bushings and washers support rotating parts within dental equipment. The self-lubricating properties reduce friction and noise.
While tough, polyimide parts can be fabricated using conventional plastics processes:
PI plastics can be injection molded to net shape with tight tolerances. This allows intricate, detailed PI plastic components to be mass-produced.
Polyimide parts are readily machined by sawing, laser cutting, drilling, milling, and turning. Carbide tooling with high cutting speeds is recommended.
Adhesive bonding, ultrasonic welding, and mechanical fasteners join polyimide parts. Surface preparations like plasma or chemical etching may help.
Polyimide plastics will continue meeting demands for ever lighter, smaller, and more reliable products especially in aerospace, electronics, and medical. Advances in polyimide materials and fabrication will open up new applications and industries for these exceptional high-performance plastics.
