This paper discusses the application of intumescent flame retardants (IFRs) in the rubber industry, especially the latest research progress on nitrogen-phosphorus synergistic IFRs.IFRs slow down flame spread by forming a stabilized charcoal layer at high temperatures, which improves the flame retardancy of rubbers and reduces the release of toxic gases. Compared with traditional halogenated flame retardants, IFR offers significant environmental advantages and cost-effectiveness. With technological progress and growing market demand, IFR has a promising application in the rubber industry, opening up a new path for the safety performance and sustainable development of rubber products.
With the continuous progress of technology and the growth of market demand, halogen-free flame retardant rubber has gradually occupied an important position in the materials market.
By selecting flame retardants with high thermal stability, optimizing processing parameters and adopting new processing technologies, manufacturers can effectively address processing temperature limitations. It helps to improve the performance and quality of flame-retardant rubber products and meet market demand and regulatory requirements.
Through a combination of cost management, technological innovation, environmental certification and industry cooperation strategies, manufacturers can meet flame retardant requirements while controlling costs and ensuring environmental and human health safety.
