Inorganic Flame Retardant AHP

The inorganic flame retardant AHP produced by Taixing adopts high-purity raw material refining and surface hydrophobic modification core technology, with Al (H ₂ PO ₂) I3 as the core component and a phosphorus content of over 42%. It has a dual flame retardant mechanism of condensed carbon layer barrier and gas-phase free radical capture, and can achieve UL 94 V-0 flame retardant with only 5% -12% addition, completely solving the industry problem of "high addition leading to performance degradation and halogen containing leading to environmental non-compliance" of traditional flame retardants. It provides compliant and efficient flame retardant solutions for fields such as wire and cable, modified plastics, and electronic sealing.

Core strengths

1. High phosphorus, high-efficiency flame retardant, low addition to reduce costs and increase efficiency

-Ultra high phosphorus content empowers strong flame retardancy: purity ≥ 99%, phosphorus content ≥ 42%, it is a rare high phosphorus product among inorganic flame retardant monomers, and the flame retardant efficiency is increased by more than 35% compared to traditional phosphorus flame retardants. After compounding with synergists such as MCA and MHB, adding 0.5% -1% to the PP system can assist in achieving V-2 grade, and adding 8% -10% to TPE/TPU wire and cable materials can achieve UL 94 V-0 grade with a thickness of 1.0mm.

-Dual flame retardant mechanism synergistic protection: on the one hand, it promotes the formation of a dense carbon layer on the substrate at high temperatures, physically blocking oxygen and heat transfer; On the other hand, the release of free radicals such as PO · and PO ₂ · interrupts the combustion chain reaction, and the limit oxygen index (LOI) can be increased from 22% of the substrate itself to over 30%.

-Zero halogen environmental protection and low pollution: completely free of halogens and heavy metals such as bromine and chlorine, no toxic and corrosive gases such as hydrogen halides and dioxins are released during combustion, smoke density (DS, 4 minutes) ≤ 160, in compliance with the EU EN 13501-1:2024 safety standard, meeting the strict requirements of low smoke halogen-free cable materials.

2. Modified and optimized adaptation, excellent processing performance

-Surface hydrophobic modification breaks through the pain point of moisture absorption: using environmentally friendly hydrophobic modification technology, the water absorption rate is ≤ 0.2% (25 ℃, soaking for 48 hours), the moisture content is strictly controlled below 0.5%, stored in a 60% humidity environment for 3 months without clumping, and can be directly fed without drying to avoid bubbles and pinhole defects caused by moisture vaporization during processing.

-Accurate and controllable particle size improves dispersibility: The average particle size D50 is 3-5 μ m, D98 ≤ 20 μ m, with no agglomeration phenomenon. It is evenly dispersed in the polymer substrate, without affecting processing fluidity. The extrusion and injection molding processes are smooth, and the product surface has no white spots or pockmarks, and the smoothness meets the standard.

-Wide temperature range processing adaptability: 1% thermal decomposition temperature ≥ 300 ℃, processing temperature window covering 200-300 ℃, suitable for extrusion and injection molding processes of PP, PVC, PBT and other materials, high temperature processing without decomposition, yellowing or volatile gas release.

3. Excellent compatibility and non-destructive mechanical properties

-Surface modification strengthens interface bonding: By using special surface treatment techniques, the interface compatibility with polymer substrates is improved. After adding TPU elastomers, the retention rate of fracture elongation is ≥ 88%, and the retention rate of PP product tensile strength is ≥ 90%, solving the problems of material brittleness and toughness reduction caused by traditional flame retardants.

-Low addition and high efficiency: Only 15-25% addition is needed to achieve UL94 V-0 grade, far lower than the 40-60% requirement of traditional inorganic flame retardants

-Processing flowability optimization: Special crystal shape control technology reduces the impact on melt flow index, suitable for thin-walled and complex structural products

4. Comprehensive compliance certification, breaking through global trade barriers

-Multiple international standard certifications: fully compliant with the EU REACH 2025 SVHC list, RoHS 2.0 (Class 10 substance control), US TSCA compliance declaration, California Prop 65 certification, and Chinese HG/T 4833-2015 implementation standards, with halogen content (Cl+Br) ≤ 50ppm and heavy metal content ≤ 0.001%.

-Multi scenario safety adaptation: smoke toxicity meets the standard, suitable for enclosed spaces such as subways, car interiors, and other environments with strict requirements for smoke toxicity; No harmful substance migration, can be indirectly used in sensitive areas such as food contact grade plastic products and electronic component protection.

-Circular economy adaptation: Waste products can be recycled through mechanical means, with no residual pollution from flame retardant ingredients, helping customers obtain green supply chain certification and break through international green trade barriers.
