Why PTFE Electronic Film?

Professional-grade material trusted by engineers worldwide.

⚡ Superior Dielectric Properties

Dielectric strength ≥ 60 kV/mm with stable dielectric constant across wide frequency range. Essential for high-frequency electronics, RF, and microwave applications.

🔌 High Frequency Performance

Low loss tangent at microwave and RF frequencies. Ideal for radar systems, satellite communications, 5G infrastructure, and high-speed digital circuits.

🧪 Chemical Resistance in Processing

Unaffected by PCB manufacturing processes — resists etching, plating, and cleaning chemicals. Maintains electrical properties after harsh processing steps.

📏 Ultra-Thin Precision

Available as thin as 0.01mm (10μm). Consistent thickness uniformity across the roll. Critical for high-precision electronic applications.

🌡️ Temperature Stable

Stable dielectric performance from -200°C to +260°C. Suitable for environments with extreme temperature cycling — aerospace, automotive, and industrial electronics.

🔬 Clean Electronic Grade

Manufactured under controlled conditions to minimize contamination. Low outgassing — safe for vacuum and space electronics applications.
