MV LD-E7 series of low-density PTFE expanded tape is designed for high frequency, low loss, stable coaxial cable design, with low dielectric constant, low dielectric loss, high tensile strength and high elongation at break, etc. Features. In addition, the large-length seamless splicing and high-strength physical performance consistency in the pressing process provide a guarantee for the winding speed of the cable production process.
Features:
Low attenuation of high frequency signal
High tensile strength and elongation at break
High temperature resistance and low linear expansion coefficient
Small thickness tolerance, high consistency of physical property parameters
Chemically stable in a wide temperature range
Thickness and width can be customized, high elongation at break
Application areas:
Coaxial cable
