LDPE>>Wire & Cable
It is a highly branched, low-density (0.91-0.93 g/cm³) specialized polyethylene, featuring excellent electrical insulation properties (volume resistivity >10¹⁶ Ω·cm) and environmental stress cracking resistance (ESCR >1000h). Its physical properties include a moderate melt index (0.3-2.0 g/10min, 190°C/2.16kg), high flexibility (elongation at break >500%), and low temperature resistance (maintaining flexibility at -70°C); its chemical properties are resistant to acids and alkalis, and moisture, but not to strong oxidants and high-temperature oils.

Wire & Cable low-density polyethylene (LDPE), with its excellent electrical insulation properties (dielectric strength > 25kV/mm), weather resistance, and flexibility, is primarily used in the insulation layer of power cables (such as low-voltage cables below 10kV), sheaths of communication cables, and buffer layers of optical cables.
