P-421 is a heavy-duty PTFE film tape that fulfills requirements for ultra-high dielectric strength, high temperature use with high to medium gauge magnet wire in larger-size components making it ideal for use in aerospace and electrical applications.
Features :
- Cured silicone adhesive enhances P-421’s ability to operate over a wide temperature range.
- PTFE backing provides low coefficient friction, which makes for a slick surface that promotes the quick movement of materials.
- Impervious to most chemical attacks, including acids, solvents, fuels and most alkalies.
Specification :
- ASTM D570, CID A-A-59474C Type I, Class 4
- BAC 5034 Type IV, Class 3B, BAC 5157
