Key Features & Properties
1. Thermal Stability for High-Density Systems
With a continuous service temperature of 250°C (482°F) , the JUTAIPEEK® NA 1mm sheet withstands prolonged exposure to soldering reflow ovens, engine bay heat, and friction-induced thermal loads. Its glass transition temperature (Tg) of ~143°C ensures that dimensional creep remains negligible even under cyclic temperature swings—a critical factor for precision spacing in electronic gap-fill applications.
2. Universal Chemical Barrier Performance
The sheet demonstrates exceptional resistance to a broad spectrum of aggressive media, including concentrated acids (e.g., sulfuric, hydrochloric), caustic alkalis, aviation fuels, hydraulic fluids, and polar organic solvents. This chemical inertness ensures that components fabricated from this 1mm sheet remain structurally sound in wet chemical processing, fuel cell stacks, and downhole oilfield sensors, where migration of hydrocarbons would otherwise compromise elastomeric seals.
3. High Stiffness-to-Weight Ratio at Minimal Gauge
Despite its slender profile, the material maintains a tensile strength exceeding 95 MPa and a flexural modulus of approximately 4.0 GPa (at 23°C). This translates to remarkable rigidity for a 1mm thickness, enabling load-bearing applications such as wafer handling end-effectors, connector locking arms, and spring-loaded valve seats. When compared to aluminum shims of equal thickness, PEEK offers superior fatigue resistance and eliminates galvanic corrosion risks in mixed-material assemblies.
4. Wear Resistance and Low-Friction Operation
The inherent lubricity and high abrasion resistance of PEEK make the 1mm sheet an excellent choice for sliding contact interfaces—such as bearing cage separators, linear guideway liners, and oscillating seal rings. Its dynamic coefficient of friction (≈0.3 against steel) remains consistent across dry-running and boundary-lubricated conditions, reducing maintenance intervals in high-cycle automation equipment.
5. Hydrolytic Stability and Dimensional Precision
With a moisture absorption rate of less than 0.5% (saturation at 23°C in water), this sheet outperforms nylon (polyamide) and polyacetal (POM) in humid environments. Parts maintain their critical dimensions—down to micrometer tolerances—even after prolonged exposure to condensation, sterilization steam, or deionized water rinsing in semiconductor cleanrooms.
6. Reliable Dielectric Performance
The 1mm sheet exhibits a dielectric strength of >20 kV/mm and a stable dissipation factor (tan δ <0.003 at 1 MHz), qualifying it for high-frequency RF shielding, automotive radar covers, and high-voltage busbar insulation where partial discharge must be strictly controlled.
7. High Purity Surface Finish
Manufactured with stringent contamination control, the JUTAIPEEK® NA grade offers a low extractable content and a smooth, void-free surface. This ensures that the 1mm sheet is ready for adhesive bonding, screen printing of conductive traces, or optical inspection without further surface preparation—a significant advantage over conventional extruded sheets that exhibit die lines or surface roughness.
