Key Properties & Performance Advantages
- Ultra-High Thermal Stability: Maintains structural integrity at continuous service temperatures up to 300°C (short-term peak up to 400°C), far exceeding the thermal limits of PEI, PPS, and PEEK for extreme heat workflows.
- Superior High Rigidity & Dimensional Stability: Glass fiber reinforcement significantly enhances flexural modulus and dimensional consistency, reducing warpage and deformation by 50-70% compared to unfilled PI—critical for precision-machined components with tight tolerances.
- Enhanced Mechanical Strength: Boosts tensile strength and load-bearing capacity by 30-50% vs. unfilled PI, resisting creep and fatigue under long-term high-temperature mechanical stress.
- Excellent Electrical Insulation: Retains PI’s outstanding dielectric properties, providing reliable electrical insulation even at elevated temperatures—perfect for high-temperature electronic and electrical components.
- Robust Chemical & Environmental Resistance: Resists strong acids, bases, solvents, fuels, and industrial fluids; tolerates radiation, vacuum, and thermal cycling, suitable for extreme semiconductor and aerospace scenarios.
- Low Moisture Absorption: Minimal moisture uptake ensures stable dimensions and consistent performance in humid or fluctuating environments, outperforming PEI and PES in moisture resistance.
