White Unsintered Low Density PTFE Insulation Tape

The major application of white unsintered low density PTFE insulation tape is for the insulation of wiring in aerospace and computer applications (e.g. hookup wire, coaxial cables). This application exploits the fact that it has excellent dielectric properties, specifically low group velocity dispersion,especially at high radio frequencies, making it suitable for use as an excellent insulator in connector assemblies and cables, and in printed circuit boards used at microwave frequencies. Combined with its high melting temperature, this makes it the material of choice as a high-performance substitute for the weaker, higher dispersion and lower-melting-point polyethylene commonly used in low-cost applications.

Storing Recommendations for Unsintered Tapes

For maximum shelf life, it is recommended that PTFE films are stored in a clean, temperature-controlled environment at or below 21C with relative humidity below 50%.
