RECENT DEVELOPMENTS IN LOW-SMOKE ZERO-HALOGEN FLAME RETARDANT POLYOLEFINS

摘要

Low-smoke zero-halogen (LSOH) polyolefin compounds typically require high levels of additives, which significantly impact mechanical properties and processability. This poses unique material development challenges. This paper presents recent developments in LSOH polyolefin technology, including novel nanoclay flame retardants, coupling technology, metal hydroxide structure-property relationships, new functional fillers for wet electrical applications, rheology of filled polyolefin systems, and fire testing methodology. These developments provide new tools for creation of novel LSOH materials.
