Opis
Our CF Reinforced PI (Carbon Fiber Reinforced Polyimide) is a top-tier modified high-performance engineering plastic, combining polyimide’s inherent ultra-high temperature resistance, chemical stability, and radiation tolerance with carbon fiber’s exceptional mechanical strength, high rigidity, wear resistance, and electrical conductivity. Engineered to outperform unfilled PI, PEI (Polyetherimide), PPS, and PEEK in extreme high-heat, high-load, and EMI-sensitive environments, this precision composite delivers unrivaled dimensional stability and long-term durability—ideal for global manufacturers seeking high-strength, low-maintenance solutions for critical industrial, aerospace, and electronic applications.
Key Properties & Performance Advantages
- Ultra-High Thermal Stability: Maintains complete 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 Strength & Rigidity: Carbon fiber reinforcement boosts tensile strength, flexural modulus, and load-bearing capacity by 40-60% compared to unfilled PI, resisting deformation under high mechanical stress.
- Excellent Wear & Abrasion Resistance: Optimized carbon fiber dispersion enhances surface hardness and friction resistance, extending service life in high-load, repetitive-motion applications far beyond standard engineering plastics.
- Electrical Conductivity & EMI/RFI Shielding: The continuous carbon fiber network provides consistent electrical conductivity and effective electromagnetic interference shielding—critical for aerospace electronics, semiconductor equipment, and high-frequency devices.
- Low Moisture Absorption & Dimensional Consistency: Minimal moisture uptake and ultra-low warpage ensure tight dimensional tolerance during precision machining, even in fluctuating temperature/humidity environments.
- Robust Chemical & Environmental Resistance: Resists strong acids, bases, solvents, fuels, and industrial fluids; tolerates radiation, vacuum, and thermal cycling, suitable for extreme aerospace and semiconductor scenarios.
