Low Dielectric Loss Fiberglass

Low dielectric loss fiber(D glass fiber) has low density,low dieletric constant and low dielectric loss.


It is an ideal reinforcement for making light weight and high performance radar masks with high wave permeability and wide frequency band and print circuit board.
