Thread Content

A new star in efficient and environmentally friendly flame retardants: Diglycol bis(chloropropyl) phosphate. In today’s context where the requirements regarding material safety and environmental performance are becoming increasingly stringent, halogen-free, low-smoke, and low-toxicity flame retardants have become the mainstream trend in market development. Among the various organophosphorus-based flame retardants, diethylene glycol bis(chloropropyl) phosphate is emerging as a standout choice due to its excellent overall performance, and it is becoming a key component in flame retardant solutions for polymer materials such as polyurethanes. I. Core product features: Diethylene glycol bis(chloropropyl) phosphate, designed for high-performance requirements; its chemical name is diethylene glycol bis-, and it is a carefully formulated organic phosphorus-chlorine synergistic flame retardant. (1) Excellent physical and chemical properties: At room temperature, this product is a colorless or pale yellow, transparent, viscous liquid; this property makes it easy to measure and mix during production. Its viscosity is precisely controlled to be within an appropriate range, which ensures good dispersion and penetration in the matrix material while avoiding processing difficulties caused by excessively high viscosity. At the same time, the product has a very high flash point and thermal stability, ensuring safety and durability during material processing and use. (II) The quality requirements are such that, in order to meet the needs of application, its chroma (APHA) is kept below 50, ensuring that it will not cause any significant color change when added to transparent or light-colored products ； It is necessary to avoid bubble formation or material degradation caused by moisture during the processing process. II. Main application areas: Focusing on polyurethanes and expanding into various applications (1) Core flame-retardant component for polyurethane foams – Diethylene glycol bis(chloropropyl) phosphate is primarily used in soft and rigid polyurethane foam plastics. Polyurethane foam has an extremely high specific surface area due to its porous structure, and it is considered a flammable material. This flame retardant can exert its flame-retardant effect through various mechanisms in both the gas phase and the condensed phase: during combustion, the phosphorus component promotes the formation of a char layer on the surface of the material, creating a protective layer that insulates and blocks oxygen ； The chlorine component can capture the free radicals in the combustion chain reaction, thereby interrupting the combustion process. This “phosphorus-chlorine synergistic effect” enables it to significantly improve the flame-retardant rating of materials with a relatively low addition amount, effectively slowing down the spread of flames. (1) Wide material compatibility: In addition to polyurethane, this product also exhibits good compatibility when compounded with other polymer materials such as epoxy resins and certain resins used in coatings. It does not have a significant negative impact on the physical and mechanical properties of the substrate, such as tensile strength and elasticity. Its liquid state allows it to be used as a reactive or additive flame retardant, enabling it to meet the formulation requirements of different customers. III. Market Prospects and Trends: Keeping Up with Trends, Bright Prospects (1) Policy Drivers and Market Demand Globally, fire safety regulations in sectors such as construction, transportation, and electronics are becoming increasingly stringent, which has greatly increased the demand for efficient flame retardants. Especially in China, as the new national standards raise the flame-retardancy requirements for building materials, furniture and other products, coupled with an increasing awareness of safety among consumers, there is a continuous and rapid growth in demand for efficient and environmentally friendly flame retardants such as diethylene glycol bis(chloropropyl) phosphate. (II) Development opportunities brought by environmental advantages: Compared with traditional bromine-based flame retardants, this product contains no halogens (bromine); it produces less smoke and fewer toxic gases during combustion, thus fully meeting the current trends toward sustainability and halogen-free design. This gives it huge market potential and room for substitution in fields with extremely high environmental requirements, such as casings for high-end electronic devices, interiors for new energy vehicles, and green building materials. IV. Conclusion: Diethylene glycol bis(chloropropyl) phosphate, thanks to its high flame-retardant efficiency, excellent processability, and outstanding environmental benefits, has become an indispensable key component in modern flame-retardant technologies. With the advancement of materials science and the increasing demands from the market for safety and environmental protection, its application value will surely receive broader recognition, and its market prospects remain promising.
