The mechanism of polyethylene breakdown in bulk at low initial stresses, relaxing during the breakdown process, is discussed. Optical, electron, and scanning microscopy were used to investigate the surface of disintegrating polyethylene for cable insulation. It was found that in prolonged tests the breakdown surface has an appearance typical for the brittle breakdown of glass polymers. It was also established that in the case of brittle breakdown with clearly expressed mirror-like and rough zones, the disintegration process passess passes through an evident deformation of the surface layer and the formation of micronecks prior to rupture. |
