PEI Natural Resin Sheets (Polyetherimide) are premium high-purity engineering plastics designed for industrial precision applications, leveraging the inherent advantages of natural PEI resin—exceptional thermal stability, flame retardancy, and chemical resistance—while ensuring uniform natural coloring and ultra-low impurity content. This material solves critical pain points of conventional colored or low-grade plastics: color fading, impurity-induced performance degradation, dimensional drift, and insufficient high-temperature endurance, outperforming ABS, Nylon, and standard thermoplastics in scenarios requiring purity, stability, and reliability.
Key Properties & Performance Advantages
- Superior Thermal & Flame Retardant Performance: Sustains structural integrity at 170°C continuous use (200°C short-term) with inherent UL94 V-0 flame retardancy, eliminating thermal deformation and fire risks in high-heat environments.
- Natural Purity & Color Stability: High-purity natural resin formula, no artificial colorants—avoids discoloration or fading under harsh conditions, ideal for applications requiring consistent aesthetics and material purity.
- Exceptional Dimensional Precision: Tight tolerance control (±0.2–2.0mm) and ultra-low moisture absorption (<0.15%) prevent size deviation, ensuring perfect fit for CNC machining and precision assemblies.
- Outstanding Chemical Resistance: Resists alcohols, solvents, acids (except concentrated sulfuric acid), and hydrolysis—avoids material degradation in industrial fluids or humid environments, extending service life.
- Versatile Processability: Compatible with CNC milling, turning, and precision cutting, adapting to custom fabrication for complex industrial components.
