Analysis Of The Phenomenon Of Counterfeiting Halogen-based Flame Retardants In Copper Terminal Blocks

The market's performance requirements for components like those in the copper terminal block series primarily focus on conductivity, mechanical strength, and flame retardancy ratings. Relatively lax regulations on chemical composition allow some supply chain players to reduce costs for copper distribution block components by "claiming bromine content" rather than actually using sufficient amounts.

Brominated flame retardants inherently possess a "hidden" characteristic in their formulations—their flame retardant effect may meet standards in short-term flame tests, but long-term thermal aging or weather resistance can significantly decline. End-users and copper terminal strip testing agencies tend to focus on initial flame retardancy testing rather than full life-cycle verification.
