Source Of Rigidity In Epoxy Resin Sleeve Material

epoxy bushing is a thermosetting polymer material whose mechanical properties originate from the three-dimensional cross-linked network formed after the resin is cured. Epoxy resin itself is a polymer formed by the reaction of epoxy groups and a curing agent. This process promotes the establishment of numerous covalent bonds between molecules, forming a dense cross-linked structure. This structure is uniformly distributed at the atomic level, thereby improving the tensile modulus and bending stiffness of the material. This allows epoxy resin bushing to maintain its shape without significant deformation when subjected to external forces, which is the basis for the widespread use of epoxy resin cast bushing in electrical insulation and industrial applications.
