Nitto NITOFLON No.903UL Fluoroplastic Adhesive Tape
product detail
Nitto NITOFLON No. 903UL is a premium adhesive tape featuring a specially oriented polytetrafluoroethylene (PTFE) film as its base material. Unlike reinforced tapes, the 903UL offers a smoother surface and better flexibility, making it ideal for wrapping complex shapes.
Coated with a high-performance silicone adhesive, it maintains stable properties over a wide temperature range. It is globally recognized for its UL510 certification, ensuring top-tier flame retardancy and electrical reliability.
Key Features:
-
Ultra-Smooth Surface: Extremely low friction coefficient for excellent sliding properties.
-
Superior Electrical Insulation: High dielectric strength, ideal for electronic components.
-
Wide Temperature Range: Performs consistently from -60°C to +200°C.
-
Excellent Chemical Resistance: Unaffected by most acids, bases, and organic solvents.
-
Flexible & Conformable: Easily adheres to curved surfaces and irregular shapes.
