Expanded PTFE Film
??????? This product is made from PTFE dispersion resin with a special fibred-structure micro-porosity by the technology of extrusion and stretching It has a lower relative density, lower dissipation loss and PTFE’s advantages so it is an ideal material for low dissipation micro-wave coaxial cable.
In comparison with “ H ” type wrapped film for cable, it has the following features and benefits.
????1. Small thickness tolerance;
????2. Low dissipation loss;
????3. Temperature-phase stability
