Spherulite-like structures in cross-linked, low density polyethylene

The subject of this paper is the relationship of the spherulite structure of cross-linked and non cross-linked, low density polyethylene and the channels that are formed in these materials by partial electrical discharges. The spherulite-like structures were produced in cross-linked polyethylene by rupturing below −70°C. The microscopic examinations were made with an optical and a scanning electron microscope.
