From September 21 to 24, 2026, THE 12TH ALL CHINA - INTERNATIONAL WIRE & CABLE INDUSTRY TRADE FAIR (Wire China 2026) will be held at the Shanghai New International Expo Center in China. YinSu Flame Retardant will be showcasing its five core product lines at Booth E7G35 in Hall E7,Whether you’re interested in power cables, control cables, communication cables, or specialty wires, we have products of various grades and applications to discuss. We welcome both new and existing customers to scan the QR code to register and visit our booth for a face-to-face discussion.
From September 15 to 17, 2026, at the Shanghai New International Expo Center, The 29th Adhesives and Sealants Expo (ASE CHINA 2026) is set to kick off. Also taking place at the same venue and during the same period are the 24th China International Rubber Technology Exhibition and the 23rd China International Chemical Industry Exhibition. Together, these three exhibitions will form “China Petrochemical Industry Week,” which is expected to attract more than 100,000 professional visitors from both China and abroad.
Bromine fell by 1,750 yuan per metric ton during the week to 37,750 yuan per metric ton, a decline of 4.6 percent. Downstream buyers were strongly pushing for lower prices, causing transaction prices to trend downward. While cost support for bromine-based flame retardants has weakened, the impact has been slow to materialize. Combined with the traditional off-season for demand, the flame retardant market is under short-term pressure and is trading on a weak note.
High-density polyurethane foam faces the “impossible triangle” of damping, flame retardancy, and strength. Yinsu Flame Retardant employs a dual-technology approach—“intrinsic flame retardancy (molecular incorporation of phosphorus-containing monomers) + surface armor (polysiloxane flame-retardant layer)”—to simultaneously enhance all three performance metrics, thereby avoiding the mechanical property degradation associated with traditional additive-based flame retardants. The LEFP series of microcellular foam materials is already in mass production and is being used in applications such as automotive shims and railroad sleeper pads.
Sulfur prices have surged 187% year-over-year, with solid sulfur in East China rising from 2,394 yuan per metric ton in 2025 to 6,871 yuan per metric ton in 2026. This week, the mainstream granular sulfur price at Chinese ports stood at 8,750 yuan per metric ton, down 300 yuan per metric ton from last week—a 3.31% decline. Nationwide port inventories stand at 878,400 metric tons. Although this represents a 5.25% increase from the previous week, it remains more than 63% lower year-over-year and is at a near-decade low. The global supply shortfall is approximately 5.13 million metric tons, with imports far below normal levels. Prices for phosphorus-based flame retardants, such as red phosphorus and ammonium polyphosphate, are prone to rise but not fall due to cost pass-through from sulfur. Coupled with successive price increases for bromine and antimony, the overall cost pressure on the flame retardant industry continues to climb.
A Comprehensive Analysis of PVC Flame Retardant Types, Synergistic Mechanisms, and the UL 94 Flame Retardancy Rating Standard. Due to the presence of plasticizers, the LOI of flexible PVC decreases significantly; therefore, highly effective flame retardancy must be achieved through synergistic blending of chlorinated paraffin, red phosphorus, antimony trioxide, and other compounds. This article provides a detailed explanation of the mechanisms of action for halogen-based, phosphorus-based, nitrogen-based, and inorganic flame retardants, covering classic case studies in applications such as PVC cable compounds, pipes, and profiles, and serves as a technical reference for formulation engineers engaged in PVC flame retardant modification.
