Flame retardants, as key additives to enhance the fire resistance of materials, have a direct impact on the safety and performance of the final product.
Efficient flame retardant performance is the primary characteristic of high-quality flame retardants. The ideal flame retardant should have a low addition amount and high flame retardant efficiency. Generally, when the addition amount is 15-30%, the material can meet the UL-94 V-0 flame retardant standard. For example, when the new phosphorus nitrogen flame retardant is added at 20%, the ultimate oxygen index of polypropylene can be increased from 18% to over 32%. At the same time, flame retardants should have a long-lasting flame retardant effect and maintain stable flame retardant performance after multiple washes or long-term use.
Environmental friendliness is an vital indicator of modern-day flame retardants. High best flame retardants need to comply with environmental rules such as RoHS and REACH, and have to now not include dangerous heavy metals and power natural pollutants. During the combustion process, it need to have the traits of low smoke and low toxicity, with a smoke density index (SDR) of much less than 100, and the quantity of CO generated ought to be managed beneath 100mg/g. For example, halogen-free flame retardants produce extra than 80% much less poisonous gases throughout combustion than usual brominated flame retardants.
Compatibility with the substrate material is key to ensuring product performance. High quality flame retardants should have good dispersibility and interfacial adhesion, without significantly reducing the mechanical properties of the material. Experiments have shown that high-quality flame retardants can maintain a tensile strength retention rate of over 85% and an impact strength retention rate of over 70% for materials. At the same time, flame retardants should have good processing performance and not affect the material's molding process.
Thermal stability and durability are the guarantees for the long-term performance of flame retardants. The thermal decomposition temperature of high-quality flame retardants should be higher than the processing temperature of the material, usually required to be above 250 ℃. During long-term use, it should have good anti migration and weather resistance. After 1000 hours of UV aging, the flame retardant performance retention rate should be above 90%. These characteristics ensure the reliability and safety of flame retardant materials in various usage environments.
