On December 13, 2025, technical information on phosphorous silica released by Guangdong Yongming Rubber shows that this functional derivative of silica modified with phosphorus is emerging as a focus across multiple industries due to its unique properties. As an innovative category of silica (also known as precipitated silica), phosphorous silica incorporates phosphorus through physical mixing, chemical reaction, or structural doping, combining silica's high specific surface area and porous structure with phosphorus's functional advantages to achieve performance enhancement.
    The material mainly includes three types: phosphoric acid silica, phosphorus-doped silica, and silica-ammonium polyphosphate composites. Prepared via specialized processes, it boasts large specific surface area, uniform pore size distribution, and abundant surface functional groups, excelling in conductivity, flame retardancy, thermal stability, and dispersibility. Currently, it is widely used in the rubber industry to improve the durability and performance of tires, shoe soles, and other products; serves as conductive or insulating filler in electronics and electrical fields; and demonstrates great potential in flame-retardant scenarios such as construction, aerospace, and automotive interiors, as well as in pharmaceutical carriers, environmental adsorbents, and agricultural pesticide carriers. With the rising demand for environmental protection and safety, the market demand for phosphorous silica continues to grow, promising broad application prospects in the future.
