    Synonyms & Product Names
    Ammonium Polyphosphate (XAP-03) is also known as "ecological ammonium polyphosphate (XAP-03)", but the full name Ammonium Polyphosphate (XAP-03) must be used in agricultural material transactions to distinguish it from ordinary fertilizers.
    Safety & Operational Standards
    When applying Ammonium Polyphosphate (XAP-03), cotton gloves must be worn to avoid direct contact with the skin. It should not be mixed with alkaline pesticides. Wash hands after application. Tie the bag tightly with the remaining fertilizer and place it in a dry place to prevent children from accidentally ingesting it.
    Application Area
    Ammonium Polyphosphate (XAP-03) agricultural grade is used for organic rice and vegetable bases as a base fertilizer for one-time application; horticultural grade is used for potted flowers and fruit trees to promote flowering and fruiting. It can reduce the use of chemical fertilizers by more than 30% in ecological planting.
    Research & Development
    Artisans are developing the symbiotic technology of Ammonium Polyphosphate (XAP-03) and nitrogen-fixing bacteria to improve nitrogen utilization. At the same time, they adjust the bacterial flora ratio according to different crops and develop special fertilizers to achieve "one fertilizer, multiple effects".
    Toxicity Research
    Ammonium Polyphosphate (XAP-03) is non-toxic and harmless to fish, birds, and bees. The oral LD50 of rats is greater than 15000mg/kg. Excessive application only makes the soil fertile in the short term, without ecological risks, and meets the standards of organic agriculture.

    Frequently Asked Questions

    As a leading Ammonium Polyphosphate (XAP-03) supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

    What is the significance of ultrafine treatment during the preparation of Ammonium Polyphosphate (XAP-03)?
    This material is made by ultrafine grinding after polymerization, using 0.1mm zirconium oxide beads as the medium, and shearing at 2000 rpm in a ceramic sand mill to reduce the particle size to less than 1μm, and the specific surface area is increased to 30m²/g, thus obtaining Ammonium Polyphosphate (XAP-03). Ultrafine grinding is like grinding ink into smoke, turning the particles from gravel into dust, which can be evenly embedded in the gaps between resin molecules. When mixed with epoxy resin, it can be dispersed after only 60 minutes of stirring without high-speed shearing, and the light transmittance reaches 85%. The transparent plastic sheet made of it can see things clearly, solving the problem of poor light transmittance of ordinary APP due to coarse particles, which is a breakthrough in flame retardancy of transparent products and broadens the application boundaries of APP.
    What extraordinary effects does Ammonium Polyphosphate (XAP-03) have in transparent plastics?
    When this product is used in polycarbonate, the addition amount is 10%, and the transmittance is still 80%, which is 40% higher than APP-2, and the haze is only 5%, which meets the needs of transparent lampshades and instrument housings. The combustion test reaches UL94 V-0 level, vertical combustion without dripping, and the carbon layer is thin and dense, which does not affect the light transmission and fire resistance. Its ultra-fine particles do not scatter light, and have a high matching degree with the refractive index of the resin. There are no pits after injection molding, and the surface gloss reaches 90GU, which is as smooth as a mirror. In the 120℃ heat aging test, the transmittance only dropped by 3%, which is much lower than the 15% of ordinary APP. Therefore, it is suitable for transparent products exposed to light for a long time, such as car headlights and display housings, which can ensure transparency and flame retardancy.
    How does Ammonium Polyphosphate (XAP-03) affect the mechanical properties of materials?
    Added to polymethyl methacrylate (PMMA), the dosage is 12%, and the tensile strength is reduced from 70MPa to 65MPa, only 7%, while APP-1 is reduced by 20% during the same period. The impact strength retention rate is 85%, and the product is not easy to crack and can withstand daily collisions. Its ultrafine particles are like skeletons, evenly dispersed in the resin, which can disperse stress and reduce cracking, such as fine sand in concrete, and enhance the overall strength. Used in transparent ABS resin, the bending modulus reaches 2.8GPa, which is only 5% lower than that without addition, meeting the mechanical requirements of structural parts. Because it has little effect on performance, it replaces traditional flame retardants in transparent structural parts, taking into account safety and practicality, and is the preferred flame retardant for transparent materials.
    What are the requirements for the dispersion process of Ammonium Polyphosphate (XAP-03)?
    It needs to be ground with a ceramic sand mill, and the medium is 0.1mm zirconium oxide beads. The speed is controlled at 1500 rpm to avoid metal contamination. After grinding, it is filtered through a 1μm filter to remove coarse particles and ensure uniform dispersion. When mixed with resin, it is pre-wetted with ethanol before adding the melt to reduce agglomeration and increase the dispersion efficiency by 2 times. Its ultra-fine particles are easy to generate dust, so it needs to be operated in a closed equipment and add a dust recovery device to protect the health of workers and reduce the loss of raw materials, so that the yield can reach 98%.
    How to balance the cost and application scenarios of Ammonium Polyphosphate (XAP-03)?
    The ultra-fine process makes the cost 20% higher than that of XAP-02, but because the addition amount can be reduced by 10%, the overall cost only increases by 5%. It is suitable for high-value-added transparent products, such as car headlights and electronic display housings. These scenarios have strict requirements on light transmittance and cannot be replaced by ordinary APP. Its performance premium is much higher than the cost increase, and it has significant cost performance in the field of high-end transparent flame retardant. Although it is expensive, it can solve the problem of balancing transparency and flame retardancy, and provide safety protection for precision transparent products. Therefore, it has irreplaceable value and helps industrial upgrading.
