PTFE Film Tape (T-730)
PTFE Film Tape | Skived PTFE Tape for Heat Sealing, Release, Low Friction & Electrical Insulation
Product Overview
PTFE Film Tape is made from skived PTFE film coated with a silicone pressure-sensitive adhesive (PSA). It is designed for applications requiring a non-stick surface, low friction, chemical resistance, electrical insulation, and reliable performance in elevated-temperature manufacturing environments.
This tape is commonly used on heat sealing equipment, release surfaces, low-friction contact areas, and selected electrical insulation applications where conventional films cannot provide the same combination of surface release, thermal stability, and dielectric performance.
Key Features & Benefits
- Non-Stick PTFE Surface:helps reduce sticking, buildup, and contamination on contact surfaces
- Low Friction Performance:supports smooth sliding, web movement, and reduced drag in processing equipment
- Electrical Insulation:suitable for selected wire, cable, coil, and electrical insulation applications
- Elevated-Temperature Capability:used in high-temperature industrial processes; exact continuous and peak ratings depend on grade and construction
- Chemical Resistance:PTFE film offers excellent chemical resistance; adhesive compatibility should be confirmed separately for actual process conditions, especially where organic solvents are present
- Converting-Friendly Supply:available in rolls, sheets, and die-cut parts for production use
Typical Applications
Heat Sealing & Release
- Release surfaces for packaging equipment and heat sealing machines
- Non-stick surface protection on hot bars, sealing jaws, and contact areas
- Release applications in composite molding and other elevated-temperature processes
Low-Friction & Web Processing
- Low-friction surfaces on rollers, guides, chutes, and sliding contact areas
- Web handling applications where smooth movement is required
- Anti-stick, low-drag surfaces in converting and industrial processing
Electrical Insulation
- Selected insulation and protection for wires, leads and electrical components where the ordered grade provides the required dielectric performance.
- Dielectric protection in applications requiring PTFE electrical properties and heat resistance
- High-performance insulation uses where grade-specific breakdown voltage and thickness are important
Chemical & Process Protection
- Surface protection in process areas where PTFE backing chemistry is required
- Selected industrial uses involving exposure to chemicals, cleaners, or process residues, subject to compatibility review
- Applications requiring a clean, low-energy surface rather than aggressive adhesion
PTFE film tape is often selected for heat sealing bars, packaging jaws, and release surfaces where low friction and clean release are required. For sealing machines, impulse sealers, L-bar sealers, and packaging lines, see our Industrial Heat Sealing guide to compare tape selection, temperature exposure, surface release, and replacement timing.
