NITTO 2 0.13X13X10M SEALER CLOTH

Nitto NITOFLON No. 973UL-S High-Performance Sealer Cloth Tape 

The Nitto NITOFLON No. 973UL-S is a professional-grade sealer cloth tape engineered for extreme heat resistance and non-stick performance. This tape features a base material of glass cloth impregnated with polytetrafluoroethylene (PTFE) and a high-strength silicone adhesive. It is a global industry standard for heat-sealing applications, vacuum packaging, and industrial machinery where a low-friction, heat-stable surface is required.

Available in multiple widths to accommodate everything from precision electronic sealing to large-scale industrial packaging lines.

Key Performance Features

• Exceptional Heat Resistance: Engineered to maintain its physical and adhesive properties at continuous operating temperatures, making it ideal for high-speed heat sealers.

• Superior Non-Stick Surface: The PTFE-coated glass cloth provides excellent release properties, preventing melted plastic or adhesives from sticking to machine parts.

• High Mechanical Strength: Reinforced with glass cloth to offer superior dimensional stability and resistance to puncture and abrasion compared to standard film tapes.

• UL Certified Flame Retardancy: Fully UL-certified for flame retardant performance (UL510), ensuring compliance with strict industrial safety standards.

• Chemical & Weather Resistant: Provides excellent resistance to chemicals, moisture, and oils, ensuring long service life in harsh processing environments.

• Smooth Friction Reduction: Offers a very low coefficient of friction, allowing materials to slide effortlessly across the surface during processing.
   

Available Sizes & Technical Specs

• Base Material: Glass Cloth + PTFE (Teflon).

• Adhesive: Pressure-sensitive Silicone.
   

Typical Applications

• Heat Sealing Machines: Applied to the heating jaws of impulse sealers and poly-bag making machines to provide a non-stick surface.

• Vacuum Packaging: Protects heating elements in vacuum sealers while ensuring a clean seal on food or industrial packaging.

• Lamination & Pressing: Used as a release sheet or protective barrier in high-temperature pressing and lamination processes.

• Wire & Cable Insulation: Provides high-temperature electrical insulation and flame-retardant wrapping.

• Chute & Hopper Linings: Reduces friction in material handling systems to prevent clogging and buildup.
   

Top 3 Customer Questions & Concerns ‍

Why choose 973UL-S (Cloth) over 903UL (Film)? The 973UL-S is reinforced with glass cloth. This makes it significantly stronger and more resistant to "cold flow" or stretching under pressure than the pure film version. It is the better choice for heavy-duty sealing where the tape is subject to constant mechanical wear.

 How do I know if this is an authentic Nitto product? Genuine Nitto NITOFLON packaging features distinct yellow branding with the green "Nitto" logo, the "973UL-S" model number, and the UL-recognized component mark. The tape itself has a characteristic brownish-tan woven texture.

Can I use this for electrical insulation? Yes. Due to its PTFE and glass cloth construction, it has excellent dielectric properties and high heat resistance, making it suitable for insulating wires in high-temperature environments.
