PVC vs. PE Cable Selection: → PE (XLPE/LSZH) excels in electrical performance (HF/HV), eco-safety (halogen-free), and low-temp flexibility. Dominates critical/sustainable applications. → PVC leads in cost, rigidity, intrinsic flame retardancy, and processability for general wiring. For high-efficiency halogen-free PE flame retardancy (e.g., LSZH), Guangzhou Yinsu Flame Retardant’s microencapsulated FRP-950X optimizes performance in infrastructure/transport.

Master LSZH cable formulation with YINSU’s expert guide: uncover the root causes—high filler load, low-temp cracking, smoke & toxicity—and the proven fixes (ADP-MCA-ATH, FRP-950X, nano-catalysts) that cut filler by 40 %, boost elongation > 320 %, and deliver UL-94 V-0, CPR B2ca/s1a/d1a compliance for rail, data-center and offshore PE cable compounds.

Low smoke zero halogen (LSZH) cables are critical for modern fire-safe wiring systems, but manufacturers face persistent challenges in both material formulation and processing. This article explores key pain points such as the contradiction between high flame retardancy and mechanical performance, thermal decomposition and bubble formation during extrusion, and interlayer delamination in multi-layer cable structures. Through advanced material innovations—like synergistic flame retardant systems and interface modifiers—and optimized extrusion techniques, cable producers can significantly improve product reliability and compliance with stringent flame retardant standards like EN 50575 and GB/T 31247. YINSU’s halogen-free flame retardant solutions, including the high-performance FRP-950X coated red phosphorus, provide tailored answers to these complex industry demands.

Low Smoke Zero Halogen (LSZH) cables are a safe alternative to traditional cables, producing minimal smoke and no harmful halogens when exposed to fire. They are widely used in public facilities, transportation systems, and industrial settings. When selecting LSZH cables, consider application requirements and compliance with standards for optimal safety and performance.

A char-forming agent, synergizing with exfoliated organically modified montmorillonite, builds a low-smoke halogen-free flame-retardant system for cables. Within the 15-min “properly crosslinked” window, it simultaneously raises XLPE tensile strength by 26 % and elevates the breakdown field strength to 42 kV/mm. The char former rapidly promotes a dense char layer, while the nano-montmorillonite delivers barrier-and-smoke-suppression effects, endowing the flame-retardant system with three key strengths: high-efficiency flame retardancy, low smoke and zero halogen, and high-voltage insulation. This offers an industrially viable innovation for next-generation eco-friendly flame retardants.
