Nitto P-422 2 Mil PTFE Film Tape
Nitto P-422 is a high-performance 2-mil PTFE film tape engineered to provide a definitive solution for high-voltage insulation and high-heat release applications across the aerospace and electrical industries. By combining a chemically inert backing with a high-temperature cured silicone adhesive, this tape ensures critical system integrity where standard films fail under thermal or chemical stress.
Nitto P-422 PTFE Film Tape delivers exceptional dielectric strength (10.5 kV), a 356°F/180°C thermal rating, and excellent conformability for reliable insulation of high-voltage coils and power cables in demanding aerospace and electrical applications.
Engineered with a PTFE film backing and cured silicone adhesive, this gray UL-510 certified tape combines chemical inertness with stable performance across a wide temperature range. Its balance of toughness and flexibility helps reduce rework while maintaining clean removal characteristics in many insulation and harnessing tasks.
What are the Key Features of Nitto P-422?

Frequently Asked Questions about Nitto P-422
How should Nitto P-422 tape be properly applied?
Surfaces must be clean and free of oil or moisture. As a pressure-sensitive tape, P-422 requires firm application by roller or hand to ensure full adhesive contact and prevent property degradation.
What is the recommended storage and shelf life for P-422?
P-422 has a shelf life of 24 months from the date of shipment. It should be stored between 50°F and 80°F (10°C to 27°C) with 25-50% relative humidity, away from direct sunlight.
Can Nitto P-422 be used in aerospace autoclave processes?
Yes, its high-temperature resistance up to 500°F makes it ideal for release ply on molds and high-heat autoclave applications in the aerospace market.
Engineer's Handling Note
When using Nitto P-422 for high-voltage connections, ensure the tape is applied to a clean, non-distorted surface to maintain its rated 10.5kV dielectric integrity. In composite curing, P-422 serves as an excellent release wrap, but professional judgment is required to allow adequate dwell time for full adhesive strength before the parts are subjected to maximum pressure cycles.
