Nitto NITOFLON No.973UL-S Fluoroplastic Saturated Glass Cloth Tape
product detail
Nitto NITOFLON No. 973UL-S is a heavy-duty industrial adhesive tape designed for high-stress environments. By combining a glass cloth base material with a polytetrafluoroethylene (PTFE) dispersion, this tape offers significantly higher mechanical strength and dimensional stability than conventional PTFE tapes.
Coated with a pressure-sensitive silicone adhesive, it provides an excellent balance of non-stick properties and durability, ensuring it won't stretch or deform even under continuous high-temperature operation.
Key Features:
-
Extreme Heat Stability: Reliable performance from -60°C to +250°C.
-
High Tensile Strength: The glass cloth reinforcement prevents shrinkage and elongation.
-
Excellent Release Properties: Low surface energy ensures a smooth, non-stick interface.
-
Chemical & Weather Resistance: Resistant to most industrial chemicals and environmental degradation.

Specifications
Application
The robust nature of Nitto 973UL-S makes it a preferred choice across various sectors:
-
Heat Sealing & Packaging: Used as a release film on impulse sealers and vacuum packaging machines to prevent plastic film sticking.
-
Roll Wrapping: Applied to rollers in extrusion coating, laminating, and dyeing processes to reduce friction and build-up.
-
Electronics: Ideal for high-temperature insulation of wires and coils where mechanical toughness is required.
-
Chute & Hopper Linings: Provides a slippery, wear-resistant surface to facilitate the flow of materials.
