What is the Degree of Cross-Linking in Cable Insulation?
The degree of cross-linking—often quantified as gel content percentage—measures the extent of chemical or physical bonding that transforms thermoplastic polyethylene (PE) into thermosetting cross-linked polyethylene (XLPE). In cable manufacturing, this process links individual polymer chains into a three-dimensional network. This structural transformation permanently enhances the material’s thermal stability, mechanical strength, and resistance to deformation under […]
