Home / Comparison of Low-Loss Performance of Melt-Draw Tapered Types
The melt strength and drawability of a low-density polyethylene (LDPE), a high-density polyethylene (HDPE) and HDPE/LDPE blends during extension flow were studied using a Rheotens test method unde.
Finally, to fully utilize the advantages of these uniplanar transmission lines, implementation of wide-band and low-loss transitions between CPW and CPS is essential . There are several types of
