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.
This article delves into the multifaceted applications of foam materials in the new energy vehicle sector, including power battery heat dissipation and protection, NVH (Noise, Vibration, and Harshness) performance enhancement, and lightweight vehicle design. It highlights how foam materials, with their lightweight, flame-retardant, sound-absorbing, and shock-absorbing properties, are driving the development of new energy vehicles.
Exploring the application of PE materials in modern industry and their flame retardant needs emphasizes the importance of flame retardants in enhancing the safety and application scope of PE materials. Flame retardants such as 950X, PEG-131, PE-XT-20 and PEFP-482 launched by Guangzhou YINSU Flame Retardant have become the preferred solutions in the industry with their excellent flame retardant properties and processing performance.
