Extreme Thermal Stability
Continuous service temperature range from -269°C to +400°C.
Glass transition temperature (Tg) exceeding 400°C.
Excellent Mechanical Properties
High tensile strength (≥200 MPa) and modulus (≥2.5 GPa).
Outstanding flexibility and tear resistance even at ultrathin dimensions (e.g., 7.5-125 μm).
Superior Electrical Insulation
Dielectric strength: ≥5,000 V/μm.
Low dielectric constant (≈3.2 at 1 kHz) and dissipation factor.
Chemical and Radiation Resistance
Resists organic solvents, acids, and radiation (gamma, X-ray).
Minimal outgassing in vacuum environments.
Lightweight and Dimensional Stability
Density: ~1.42 g/cm³, making it lighter than many metal alternatives.
Low coefficient of thermal expansion (CTE: 30-50 ppm/°C).
Flame Resistance
UL 94 V-0 rated; self-extinguishing without emitting toxic fumes.
Application Scenarios
Aerospace and Aviation
Used as thermal blankets, insulation for spacecraft wiring, and protective layers in satellite components due to its radiation resistance and thermal stability.
Electronics and Semiconductors
Employed as flexible printed circuit (FPC) substrates, coverlays, and stress buffers in microelectronics packaging for smartphones, wearables, and displays.
Energy and Electric Vehicles
Serves as insulation films for lithium-ion batteries, motor slot liners, and high-voltage capacitor dielectrics in EVs and renewable energy systems.
