Property	Low Density	High Density
Dielectric constant	Lower (better signal)	Slightly higher
Dielectric strength	Medium	High
Voltage resistance	Medium	Excellent
EMI / insulation reliability	Good	Very stable & reliable

Cable factories often choose:

Low density → signal performance, lightweight cables

High density → insulation safety, durability, high voltage
