Description
DBDTT550
Daflon 550 tubing is extruded from PTFE resin and is unmatched by any other tubing for use in applications for hi-frequencies and hi-temperatures. Rated for continuous operation of 250°C, it retains its toughness and flexibility throughout. It has high resistance to fatigue and stresses, superior dielectric strength at high frequencies. It will not shrink back during soldering operation. Daflon tubing is flexible and non-flammable. It permits miniaturization of design and compactness, and has the lowest coefficient of friction. In addition, it is inert to all fungus growth.
