The Surface Of Copper Terminal Block Housings Is Prone To Whitening After Using Low-smoke Halogen-free Materials.

Many customers have reported that, even when using Low Smoke Halogen-Free (LSZH) material for the copper terminal block casing, scratches or minor impacts may occur during handling, installation, or debugging, causing the copper distribution block casing surface to lose its original luster and appear white or spotted.

This phenomenon is related to the physical properties of LSZH material itself. As a material that emphasizes environmental protection and fire safety, LSZH material reduces the release of smoke and harmful gases during combustion, making it widely favored in applications with high safety requirements, such as copper terminal strip and cable interfaces.
