PTFE Film Tape

Product Description

The PTFE Skived Film Tape J-730 combines advanced materials and precision manufacturing to meet rigorous application requirements:

• 100% Pure PTFE Film Base

  • Uniformly skived from high-grade PTFE blocks to ensure consistent thickness and surface quality.

  • Naturally hydrophobic and chemically inert, making it ideal for contamination-sensitive processes.

• High-Performance Silicone Adhesive

  • Pressure-sensitive silicone provides excellent initial tack on metals, plastics, and composite surfaces.

  • Clean removal without residue—even after prolonged exposure to heat or chemicals.

• Smooth, Non-Stick Surface

  • Coefficient of friction as low as 0.05, reducing adhesion of molten resins, adhesives, and tapes.

  • Enables easy cleanup, minimizes downtime, and prevents damage to delicate surfaces.

• Wide Operating Temperature Range

  • Continuous use from –70 °C to 260 °C; can withstand brief exposure up to 300 °C.

  • Maintains mechanical and adhesive properties under thermal cycling.

• Superior Dielectric Strength

  • ≥ 40 kV/mm, offering robust electrical insulation for coils, capacitors, and wiring harnesses.

• Chemical Inertness

  • Resistant to strong acids (e.g., sulfuric, hydrochloric), bases (e.g., sodium hydroxide), fuels, oils, and most organic solvents.

  • Prevents tape degradation and process contamination.

By integrating these core attributes, the J-730 tape ensures consistent, long-lasting performance in applications that demand both high-temperature stability and electrical or chemical resilience.

Features

1. Ultra-Low Friction & Non-Stick Performance

   • Coefficient of friction as low as 0.05 for smooth release of adhesives, tapes, and resins.

   • Prevents material buildup on rollers, molds, and conveyors.

2. High-Temperature Endurance

   • Continuous service at temperatures from –70 °C to +260 °C.

   • Short spikes up to 300 °C for soldering and heat-treat processes without adhesive bleed or film degradation.

3. Outstanding Dielectric Insulation

   • Superior electrical isolation for winding coils, capacitors, and shielding sensitive components.

4. Chemical & Corrosion Resistance

   • Withstands aggressive acids, alkalis, solvents, and oils found in chemical processing, plating, and pharmaceutical lines.

   • Ideal for environments where cleaning agents or sterilization cycles are used.

5. Silicone Adhesive Advantages

   • Excellent tack and adhesion to a broad range of substrates, including metals, ceramics, and composites.

   • Clean removal after extended outdoor or oven exposure—no sticky residue or adhesive transfer.

6. Mechanical Robustness

   • High tensile strength and elongation ensure the tape can be stretched or wrapped tightly without tearing.

   • Maintains dimensional stability under pressure and mechanical stress.

7. Longevity & Cost Efficiency

   • Durable PTFE film resists wear, abrasion, and repeated handling, extending service intervals.

   • Low maintenance and replacement costs due to minimal adhesion of contaminants.
