Addition-cure liquid silicone rubber (ALSR) has become the preferred choice for insulating materials and semi-conductive materials for cable accessories due to its excellent electrical and mechanical performance. Affected by the purity of raw materials

crosslinking network and filling level

there is a certain gap between ALSR in China and the international advanced level in terms of key performance. This paper reviews the performance requirements

research progress of ALSR insulating materials and semi-conductive materials for cable accessories

focuses on the influence of fillers on the mechanical and electrical performance of ALSR

and summarizes the mechanism of filler amount

morphology and dispersion on the macroscopic performance of ALSR. Finally

the research trends of ALSR insulating materials and semi-conductive materials for cable accessories are envisioned

including the design of polymer chain structure and crosslinking network

the development of novel functional fillers

the enhancement of raw material purity and batch stability

and the development of low-cost raw material synthesis and purification technologies. This research can provide insights for the development of high-performance silicone rubber materials for cable accessories.
