Low Density PTFE (LD-PTFE)

Low density (LD) PTFE tape is made from an expanded, pure PTFE designed to achieve low dielectric constant, crush resistance, fast elastic recovery, and high tensile strength for microwave and coaxial cable applications. Besides excellent electrical, thermal and chemical properties, low density PTFE tape provides reduced signal loss in high performance cables when handling microwave energy in the high frequency (GHz) range.

Low density PTFE tape is made through a “stretching” process that results in the enlargement of the pores structure, which makes it an excellent dielectric for wire and cable where low dielectric constant and high signal speeds are required.
