- Abstract
- The crosslinking of polyethylene of pipe grades via 900 keV electrons at an absorbed dose of 50 to 400 kGy in the presence of antioxidants and a crosslinking agent was studied. The degree of crosslinking of polyethylene was measured by the content of the gel fraction, determined by its extraction in xylene. It was shown that in all cases the 60% degree of cross-linking is achieved at a dose of about 100 kGy. It is advisable to combine the standard method for determining the gel fraction with visual inspection of samples to identify the conditions for the formation of an excessively low-melting material. It has been shown that ±7% crosslinking degree non-uniformity can be achieved with dose non-uniformity of up to ±50%.
