Specialized in PE, PVC, TPE, TPU and Low Smoke Zero Halogen (LSZH) wire and cable compound and materials.
In high-rise buildings, subway tunnels, new energy power stations and industrial complex scenarios, the fire safety of wires and cables is directly related to life and property and system reliability.
YINSU Flame Retardant Company provides customized flame retardant solutions for global customers, covering PE (polyethylene), PVC (polyvinyl chloride), TPE (thermoplastic elastomer), TPU (thermoplastic polyurethane) and LSZH (low smoke and halogen free) wire and cable systems to meet all safety requirements, ranging from UL94 V-0 flame retardant certification to EN 45545 fire protection for rail transportation and IEC 60754 low smoke and halogen free toxicity. All-round safety requirements.

A single-strand combustion test can only demonstrate that the cable material itself is self-extinguishing, whereas bundle combustion testing is the “ultimate test” for evaluating a cable bundle’s ability to resist flame spread in a real fire. The challenges of bundle combustion testing lie in the chimney effect causing heat accumulation, molten droplets igniting materials below, and auxiliary materials such as filler ropes acting as flame pathways. The silver-plastic flame-retardant K100 nano-organic montmorillonite char-forming synergist, through intercalation modification technology, forms a dense, barrier-like char layer during combustion that traps molten material to prevent dripping. When used in conjunction with primary flame retardants such as ATH and MDH, it helps ensure consistent success in bundle burning tests.
The leaching of flame retardants from corrugated pipes causes surface whitening, frosting, and a decline in performance; the root cause lies in the poor compatibility between the flame retardants and the PE substrate. YinSu Flame Retardant Company offers PE-XT-141 non-leaching flame-retardant masterbatch and the FRP-950X red phosphorus flame-retardant solution, which address the leaching issue at its source and ensure long-term stability of flame-retardant performance.
GB 8624-2023 has included building piping materials within the scope of Class B1 flame retardancy. Rigid PVC pipes coated with 8 parts of red phosphorus can meet Class B1 requirements, while their ring stiffness and drop-weight impact resistance comply with GB/T 10002.1. Flame retardancy requirements for piping materials used in high-rise buildings, subways, and data centers are shifting from “optional” to “mandatory.”
Why does the flame retardancy of recycled PVC boards fluctuate wildly between V-0 and V-2 during processing? To address the "thermal history" damage of regrind, YINSU Flame Retardant offers highly heat-stable composite antimony solutions that secure consistent UL94 V-0 ratings while boosting mechanical retention by 30% and driving significant cost optimization.
Flexible PVC struggles with flame retardancy: too much plasticizer kills V 0, too little makes it hard. YINSU Flame Retardant provides antimony trioxide substitutes and magnesium aluminium synergy that keep softness while passing V 0 stably, with cost optimisation of 15% or more.

PVC flame retardancy is not about simply adding more additives – flexible PVC requires extra flame retardants to offset the flammability risks introduced by plasticizers. YINSU Flame Retardant offers synergistic systems and antimony trioxide alternatives to help you pass V-0 and low smoke tests at a more competitive cost.
