Halogen-Free Solutions for Specialty Cable Design Utilizing Different Thermosetting Chemistry
Halogen-free flame-retardant (HFFR) cable compounds are increasingly required to meet modern safety and environmental standards. However, their high filler loading complicates processing and narrows extrusion windows. Conventional crosslinking approaches—peroxide-based continuous vulcanization (CV) and silane-based moisture curing—remain widely used but face notable limitations. Peroxide CV requires high temperatures and produces chemical by-products, while silane cure is slow and moisture dependent, often restricting uniform curing in thick constructions.
