Taixing is a professional manufacturer that produces powdered melamine cyanurate using precision air jet milling and hydrophobic coating modification core technology, creating a powdered product with narrow particle size distribution and excellent flowability. With a nitrogen content of ≥58.5%, it combines heat absorption, dilution, and char formation as three flame-retardant mechanisms. Only 8%-22% addition is required to achieve UL 94 V-0 flame retardancy. This completely resolves the industry challenges of traditional products—difficulty in dry processing, poor dispersibility, and significant mechanical performance loss—providing cost-effective flame-retardant solutions for global modified plastic manufacturers.
1. Ultra fine powder process, with excellent dispersion and dispersion performance
-Innovative graded airflow crushing technology: abandons the problems of coarse particles and agglomeration in traditional mechanical crushing, and achieves ultrafine material crushing through supersonic airflow impact and collision. The average particle size D50 is precisely controlled within 2-5 μ m, D98 ≤ 15 μ m, and the particle size distribution is uniform without large particle impurities.
-Excellent dispersibility suitable for dry process: The powder has a resting angle of ≤ 32 ° and can be stored in a 60% humidity environment for 3 months without clumping or moisture absorption aggregation. It can be directly mixed with resins and additives for dry mixing without the need for additional dispersants, resulting in a 30% increase in mixing efficiency and a significant reduction in production cycle.
-Dispersion uniformity ensures product quality: Micron level uniform dispersion can be achieved in substrates such as nylon and PE, avoiding the "white spots" and "pockmarks" defects of traditional granular MCA dry modification. The surface smoothness of the product reaches mirror level, meeting the production requirements of appearance parts.
2. The synergistic triple flame retardant mechanism effectively blocks the combustion process
-Building a good "heat absorption and cooling+gas phase dilution+condensed phase carbonization" three in one flame retardant system: at high temperatures above 320 ℃, powdered MCA quickly absorbs heat and decomposes, releasing inert gases such as nitrogen and carbon dioxide to dilute the oxygen concentration in the combustion zone; At the same time, the decomposition products promote the formation of a dense and continuous carbon layer on the surface of the substrate, physically blocking heat transfer and oxygen permeation, and fundamentally blocking the combustion chain reaction.
-Low addition amount for efficient flame retardancy: Adding 12% to pure PA6 system can achieve a thickness of 1.6mm UL 94 V-0 grade, and when used in combination with aluminum hypophosphite, the addition amount can be reduced to 8%; Adding 20% to PE cable material can increase the Limiting Oxygen Index (LOI) to over 30% according to the IEC 60332-1 cable flame retardant standard.
-Zero halogen, low smoke, low toxicity and environmental protection properties: There is no release of toxic and corrosive gases such as hydrogen halides and dioxins during the combustion process. The smoke density (DS, 4 minutes) is ≤ 150, and the smoke toxicity meets the EU EN 13501-1:2024 safety standard. It is suitable for scenarios with strict requirements for smoke toxicity, such as automotive interiors and enclosed electronic devices.
3. Hydrophobic coating modification, balancing processing performance and mechanical properties
-Adopting environmentally friendly hydrophobic silane coupling agent coating technology: constructing a hydrophobic protective film on the surface of the powder, with a water absorption rate of ≤ 0.2% (24-hour immersion test), far lower than the 0.5% of ordinary powdered MCA, effectively avoiding powder floating and agglomeration problems during wet modification, and improving interface compatibility with non-polar substrates (such as PE).
-Wide temperature range thermal stability compatible with multiple processes: 1% thermal weight loss temperature ≥ 315 ℃, processing temperature window covering 240-330 ℃, can be matched with high-temperature extrusion and injection molding processes of engineering plastics such as nylon and polyester, and is also suitable for low-temperature granulation of EVA cable materials. High temperature processing has no decomposition, no volatile gas release, no mold sticking, and no mesh blockage.
-Minimizing the loss of mechanical properties: The addition has minimal impact on the mechanical properties of the substrate. The retention rate of the notch impact strength of PA6 products is ≥ 88%, and the retention rate of the fracture elongation of PE cable materials is ≥ 85%. It perfectly balances the flame retardant performance and material toughness, meeting the mechanical requirements of structural components.
