Introduction to Polyimide Plastics

Polyimide plastics contain long chains of imide monomers that impart key attributes like:

  • High heat resistance
  • Excellent chemical resistance
  • High mechanical strength
  • Good dielectric properties

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.

Aerospace and Aviation Applications

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.

Polyimide Insulated Aerospace Wire

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.

Jet Engine Components

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.

Polyimide Plastic Uses in Electronics

With good insulation properties and heat resistance, PI plastics serve well in electronics applications including:

Flexible Printed Circuits

Flexible printed circuits frequently use polyimide plastic film substrates. PI plastic films provide flexibility along with thermal and chemical stability for long life.

Wire and Cable Insulation

PI plastic films or tubing insulate wires and cables in consumer electronics and industrial equipment. The high dielectric strength resists electrical breakdown.

Circuit Boards

Glass fiber reinforced PI laminates are used to fabricate printed circuit boards. The dimensionally stable PI plastic boards withstand soldering temperatures.

Automotive and Machinery Applications

Polyimide parts withstand friction, wear, and high heat in automotive and machinery environments:

Bushings and Washers

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.

Wear Pads

PI plastic wear pads protect equipment while resisting abrasion. Used in escalators, conveyors, and other machinery. The self-lubricating nature reduces maintenance.

Motor Insulation

Wire insulation made of polyimide withstands the high heat conditions within electric motors. It helps prevent short circuits in generator windings too.

Polyimide for Medical Devices

PI plastics meet the demanding requirements of medical device applications:

Implants and Prosthetics

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.

Dental Equipment

Wear-resistant PI plastic bushings and washers support rotating parts within dental equipment. The self-lubricating properties reduce friction and noise.

Fabricating and Machining PI Plastic Parts

While tough, polyimide parts can be fabricated using conventional plastics processes:

Injection Molding

PI plastics can be injection molded to net shape with tight tolerances. This allows intricate, detailed PI plastic components to be mass-produced.

Machining Methods

Polyimide parts are readily machined by sawing, laser cutting, drilling, milling, and turning. Carbide tooling with high cutting speeds is recommended.

Joining Techniques

Adhesive bonding, ultrasonic welding, and mechanical fasteners join polyimide parts. Surface preparations like plasma or chemical etching may help.
