PI
Key Properties of PI
These properties make Polyimide (PI) suitable for applications where components must retain stability, insulation performance, wear resistance, and mechanical reliability under continuous heat and severe operating conditions.
PI Industrial Applications
Polyimide (PI) components are used in applications where heat, electrical insulation, friction control, and dimensional stability are critical to long-term performance.
Polyimide (PI) is suited for demanding applications where components must maintain thermal stability, insulation performance, low wear, and mechanical reliability in extreme operating environments.
PI Stock Shapes
Plastic Engineering Solution supplies Polyimide (PI) in stock shapes and machined forms for applications where thermal stability, insulation performance, and dimensional reliability are essential.
PI Rods
PI Plates
PI products are typically selected for high-temperature, low-wear, electrically insulating, and precision applications where long-term performance is required under severe operating conditions.
PI Grades Supported
We support a range of Polyimide (PI) material grades selected for high-temperature, insulation, and precision-performance applications.
Our team helps select the right PI grade based on heat exposure, electrical insulation needs, wear conditions, dimensional stability requirements, friction performance, and the expected operating environment.
PI Machining
Polyimide (PI) is used for precision components where heat resistance, insulation performance, and dimensional stability are critical. Machining PI requires careful control of cutting parameters to protect surface quality, maintain accuracy, and avoid stress on the material.
Our PI machining capability includes:
- CNC turning and milling
- Precision profiling and contouring
- Insulation component machining
- Bushing, bearing, seal, and wear-ring manufacturing
- Prototype and repeat production
- Machining for high-temperature and electrical applications
For PI components, machining is planned around the final operating environment — especially where heat, friction, insulation, and dimensional control influence long-term performance. This helps deliver clean finishes, accurate dimensions, and reliable performance in extreme industrial applications.
PI Machining Tolerances
Polyimide (PI) machining tolerances depend on:
Component geometry
Wall thickness
Application requirements
 Heat exposure conditions
Part size and complexity
Friction and wear environment
Insulation or sliding fit requirements
Typical achievable tolerances are maintained as per design feasibility, with tighter tolerances possible for precision applications after engineering evaluation.
Detailed tolerance information can be provided during the RFQ stage.
