Our PI Profiles (Polyimide Rods & Sheets) represent the pinnacle of extreme-environment engineering plastics, integrating unparalleled ultra-high temperature resistance, exceptional chemical stability, and superior mechanical strength. Engineered to outperform PEI (Polyetherimide), PPS, and PEEK in the most demanding thermal, chemical, and mechanical scenarios, this precision-manufactured PI material delivers uncompromising dimensional consistency and long-term reliability—ideal for global manufacturers seeking high-performance solutions for critical applications where conventional plastics fail.
Key Properties & Performance Advantages
- Ultra-High Thermal Stability: Sustains structural integrity at continuous service temperatures up to 300°C (short-term peak up to 400°C), far exceeding PEI, PPS, and PEEK’s thermal limits for extreme heat workflows.
- Exceptional Chemical Resistance: Resists strong acids, bases, solvents, fuels, and industrial fluids, with chemical compatibility that outperforms most engineering plastics—ensuring durability in harsh corrosive environments.
- Superior Mechanical Strength: Boasts high tensile strength, stiffness, and wear resistance even at elevated temperatures, paired with low moisture absorption and minimal warpage for precision machining.
- Broad Environmental Adaptability: Tolerates radiation, vacuum, and extreme temperature fluctuations, making it suitable for aerospace and semiconductor high-purity applications.
- Dimensional Consistency: Precision extruded/machined with strict quality control, ensuring uniform thickness and shape retention—reducing production waste and post-processing costs.
