Lanmar's PTFE coated fiberglass tape combines the structural integrity of a woven fiberglass substrate with the non-stick, heat-resistant surface of PTFE — producing a tape that performs reliably in conditions that standard adhesive tapes cannot survive.

Available in two adhesive systems to match your application temperature:

   • Silicone adhesive — rated to 500°F (260°C). The standard choice for heat sealing equipment, packaging machinery, and high-temperature industrial applications.

   • Acrylic adhesive — rated to 350°F (177°C). A cost-effective option for moderate-temperature release and anti-friction applications.

Both versions are available with or without a release liner (self-wound). Premium Grade tapes offer a glass-smooth surface finish with enhanced tensile strength, dimensional stability, and extended wear life — ideal for demanding heat sealing jaws and platens where surface consistency directly affects seal quality.

Common applications include packaging and heat sealing equipment (jaw covers, bar covers, platen liners), food processing conveyor surfaces, screen printing platens, anti-friction guide surfaces, mold release layers in composites manufacturing, and wire harness protection in aerospace and automotive assemblies.

PTFE coated fiberglass tape is FDA-compliant for food contact applications. All rolls are available custom-slit to any width. We cross-reference to 3M 5151, Taconic, Saint-Gobain, and CS Hyde equivalents — contact us with your current part number for a direct match.

PTFE film tapes deliver the non-stick and chemical-resistant properties of pure PTFE in a thin, conformable format — without the bulk of a fiberglass substrate. Lanmar stocks two distinct configurations to match the specific demands of each application.

 High Modulus PTFE Film Tape — Premium Grade:

Made from oriented PTFE film, high modulus tape offers low elongation and high wear resistance. It maintains its dimensions under tension and repeated thermal cycling, making it the right choice for heat sealing jaws, wire wrapping in transformer and coil manufacturing, and electrical insulation in capacitors and slot liners where both dielectric performance and dimensional control are critical.

 Skived PTFE Film Tape — Standard Grade:

Manufactured by skiving (shaving) PTFE block material into a thin film, skived tape offers high elongation and excellent conformability to irregular surfaces. Its combination of ultra-low friction, chemical resistance, and dielectric strength suits it for wire and coil insulation, masking applications, anti-friction surfaces, and any high-temperature application where the tape must conform tightly without wrinkling.

 Both configurations are available with high-temperature silicone adhesive. Skived tape is typically self-wound without a liner. All widths are available custom-slit from stock. Contact Lanmar to cross-reference Saint-Gobain CHR 2255, Taconic TAC-TAPE 6115/6445, or similar products.

Ultra-high molecular weight (UHMW) polyethylene tape is the preferred choice when the operating environment is below 150°F (66°C) and the priority is abrasion resistance, impact toughness, and sustained low friction — properties where UHMW outperforms PTFE at a lower cost.

UHMW tape's extremely low coefficient of friction creates a smooth, slick running surface that reduces drag, eliminates squeaks, and extends the service life of sliding, guiding, and conveying components. Its resistance to abrasion and puncture makes it far more durable than PTFE film in high-wear contact applications.

Primary applications include:

   • Chute liners — prevents buildup and reduces noise in gravity-fed material handling

   • Rail liners and guide surfaces — smooth contact interface for conveying systems

   • Turn-bars and deflectors — low-friction surface for web handling in converting lines

   • Vehicle panels, trim, and door edges — scratch and wear protection

   • Anti-friction bearing surfaces and machine slides

UHMW tape is also resistant to moisture and most common industrial chemicals, performing reliably in wet or corrosive environments. Available in multiple thicknesses and custom-slit widths. Acrylic adhesive backing provides a firm bond to most substrates.

Lanmar's Polyimide Film Tapes are specifically designed for high-temperature electrical insulation and UV sealing applications. Polyimide is a high-performance polymer that offers excellent thermal and electrical insulation properties, making it an ideal choice for use in a wide range of industrial and commercial applications.

Polyimide film is a very thin film with high temperature and electrical tolerances, making it ideal for use in applications that require high levels of precision and accuracy. The film is commonly used in RF sealing applications, as well as in the aerospace and electronics industries.

It's worth noting that Polyimide film is not a release-surface product in stock as .001” and .002” pressure-sensitive tapes. However, Lanmar can provide custom Polyimide tape solutions tailored to your specific needs and requirements. With a range of thicknesses and adhesive options available, we can work with you to create a Polyimide tape solution that meets your unique specifications and delivers exceptional performance in even the most demanding environments.

Lanmar Glass Cloth Tapes (without PTFE) have many exceptional properties that make them ideal for a wide variety of applications. In addition to their high temperature stability, they also possess exceptional cut-through and abrasion resistance, as well as excellent flexibility. These tapes are perfect for use in electrical insulation applications for cables, motors, and transformers.

Our double-faced glass cloth tape is particularly useful for masking parts in plasma spraying, HVOF and grit blast applications. Item #775-8R is our Plasma Spray Masking tape, which also doubles as a "Friction Tape" due to the sticky surface of the silicone rubber coating. It can be used as a spiral wrap for rollers and on drive wheels.

For applications that require high heat tolerance and reflectivity, we offer a tape (#725-7) that is made by laminating aluminum foil to fiberglass cloth. This tape is commonly used in many electrical and insulation applications.

Polyester Film tape is a versatile product designed for various splicing, holding, or masking applications. It is composed of a strong and durable polyester film backing that offers excellent dimensional stability, chemical resistance, and electrical insulation properties. The high tack silicone adhesive provides a reliable bond and does not leave any residue upon tape removal. Polyester Film tape is stocked in blue color and available in various widths and lengths. Custom colors and sizes are also available upon request. With a high temperature resistance, this tape is ideal for use in the electronics, automotive, and industrial sectors where high temperature and clean removal are critical requirements.

Lanmar PTFE zone tape provides reliable non-stick release and heat resistance for sealing jaws and packaging equipment. Designed to reduce downtime, prevent adhesive buildup, and extend equipment life.
