Flame retardancy in adhesives is often compromised by white spots caused by uneven dispersion of flame retardants, or by an acidic pH that affects bond strength. The silver-plastic flame retardant WADP-10 has been specially modified to offer excellent dispersion and a near-neutral pH; it does not interfere with curing, does not corrode substrates, and provides stable peel strength. MCA-B is suitable for nylon and oil-based adhesive systems, meeting the dual requirements of V-0 flame retardancy and bonding performance.
Antimony prices remain stuck at high levels, with antimony trioxide holding steady at 95,000–98,000 yuan per metric ton, while bromine has risen in tandem to 37,000–37,500 yuan per metric ton, keeping cost pressures on flame retardants high. Zimbabwe’s export ban has exacerbated supply disruptions, and with downstream demand remaining weak, the market is caught between rising and falling prices. This has further opened the window for evaluating antimony-free alternatives.
FPC, FFC, and electronic potting compounds—uneven flame retardancy in ultra-thin coatings, component contamination, and failure due to high temperatures during reflow soldering are the three major challenges in flame retardancy for electronic adhesives. Yinsu’s YS-F22B ultra-fine halogen-free flame retardant (comparable to Clariant OP930), with a D95 particle size of ≤10 μm, is hydrolysis-resistant, non-migrating, and does not contaminate components. It achieves UL94 V-0 compliance at low loading levels and is suitable for high-end electronic adhesive applications such as FPCs, FFCs, electronic potting compounds, and label adhesives.
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.”
The PE-XT-141 bromine-antimony masterbatch, developed by Yinsu Flame Retardant Company, is a reactive and additive flame-retardant masterbatch that directly addresses the issue of “passing tests but failing on the production line.” This article introduces the product’s key selling points and answers several questions frequently asked by engineers.
