PTFE film tape (Teflon tape)
PTFE film tape made by Polytetrafluorethylene widely applied in wrapping -insulated-shield material for Aerospace cable.
PTFE film tape has emerged as a premier choice for aerospace cable wrapping insulation tape materials, attributed to its exceptional characteristics: With a wide range from -55℃ to 260℃, PTFE tape can withstand extreme environmental conditions.Superior fire resistance and insulation significantly enhance the safety performance of cables.The wrapping process, as opposed to traditional extrusion methods, yields thinner and lighter cables. Customized colors are suitable for multi-core cables, with laser marking capabilities.
