PI Series ｜ Polyimide Components for Ultra-High Temperature & Specialized Applications
🌟 Key Takeaways
- PI Series is a high-performance plastic component series made from PI (Polyimide)
- The PI material used is a thermosetting resin, not a thermoplastic
- Supports the highest continuous operating temperature among resin materials
- Continuous service temperature: ~300°C (572°F)
- Excellent thermal stability, dimensional stability, and mechanical performance at high temperatures
- Low Outgassing, suitable for vacuum environments
- Electrical insulation, non-magnetic, flame retardant (UL94 V-0)
- Ideal for semiconductor equipment, aerospace, production machinery, high-temperature furnaces, and medical devices
🔷 What Is the PI Series
The PI Series is a high-reliability plastic component line developed by
Nippon Chemical Screw Co., Ltd.
for applications where extreme heat resistance and long-term material stability are essential.
The PI (Polyimide) used in this series is classified as a thermosetting resin.
Unlike common thermoplastic engineering plastics, it does not soften easily at elevated temperatures and maintains stable properties over long service periods.
As a result, PI is positioned as a top-tier resin material with the highest usable temperature range.
🔷 When High Temperature Is a Normal Operating Condition
In advanced industrial fields such as:
- Semiconductor manufacturing equipment
- High-temperature furnaces
- Continuous production systems
- Aerospace-related devices
components are expected to withstand:
- Continuous exposure to high temperatures
- Heat accumulation and thermal cycling
- Long-term material degradation risks
Under such conditions, material softening, deformation, or gas release can directly lead to process instability.
The PI Series is designed with these conditions as a baseline, ensuring stable performance and long-term reliability in demanding environments.
🔷 Key Material Properties of the PI Series
- Exceptional thermal stability: Continuous use up to ~300°C
- Outstanding dimensional stability: Minimal deformation under high temperatures
- Low Outgassing: Suitable for vacuum and clean processes
- Stable mechanical properties at elevated temperatures
- Electrical insulation and non-magnetic behavior
- Flame retardant (UL94 V-0)
🔹The PI Series is engineered for stable operation and long-term reliability in high-temperature environments.
🔷 Typical Application Fields
🔌 Semiconductor Manufacturing Equipment
Used in high-temperature process areas where low outgassing, dimensional stability, and material reliability are critical.
✈️ Aerospace Applications
Suitable for components requiring both high heat resistance and long-term reliability.
🩺 Medical Devices
Applied to specialized parts where thermal stability and material consistency are required.
💡 Industrial Summary
The PI Series is optimized for industries demanding high temperature resistance, vacuum compatibility, and long service life.
🔷 Suitable Usage Conditions
- Operating temperatures exceeding PEEK or PPS limits
- Vacuum environments requiring Low Outgassing
- Applications demanding long-term dimensional stability
- When a resin-based material is preferred over ceramics
- Material selection prioritizing the highest temperature capability among polymers
🔷 Next Material Selection Step
If the application requires:
- Temperatures exceeding 300°C
- Maximum rigidity and zero deformation
👉 CERAMIC (Alumina) Series becomes the next and final material option.
📘 Summary
The PI Series is a high-performance polyimide component line using thermosetting resin technology, offering the highest heat resistance among polymer materials.
It supports stable and reliable operation in semiconductor equipment, aerospace systems, production machinery, high-temperature furnaces, and medical devices where extreme thermal conditions are unavoidable.
