Dielectric breakdown of new type polymerized polyethylene using a single-site catalyst

We investigated the dielectric properties of a new type of polyethylene (PE) polymerized with a single-site catalyst. The new PE has much higher dielectric 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 comonomer and melt flow rate (MFR) scarcely affect the dielectric properties.
