We investigated the dielectric properties of a new type of polyethylene (PE
) polymerized with a single-she catalyst. The new PE has much higher dielec
tric strength and volume resistivity than both conventional low-density PE
and linear low-density PE. The increase in the density is considered to be
responsible for the increase in dielectric strength. The type of the comono
mer and melt flow rate (MFR) scarcely affect the dielectric properties.
