Granular MCA Flame Retardant

The granular MCA flame retardant developed and produced by Taixing breaks the pain points faced by traditional powdered MCA, such as "dust pollution during feeding, low measurement accuracy, and severe equipment wear". Innovatively adopting the core technology of powder dense granulation and coating anti powdering modification, ultrafine MCA powder is transformed into high-strength regular particles with a nitrogen content of ≥ 58.5%. It has a triple flame retardant mechanism of heat absorption, dilution, and carbonization, and can achieve UL 94 V-0 flame retardant with only 10% -22% addition, completely solving the industry problems of "dust hazard, measurement error, and low production efficiency" of traditional powder products. It provides a clean, efficient, and stable flame retardant solution for global large-scale modified plastic enterprises.

Core strengths

1. Dense granulation technology, dual guarantee of clean production and precise measurement

-Innovative high-pressure rolling screening shaping process: After high-pressure dense molding, ultrafine MCA powder is obtained through graded screening to obtain uniformly sized 1-3mm regular particles with a compressive strength of ≥ 15N. There is no crushing or pulverization during automated feeding and mixing processes, and the workshop dust concentration is ≤ 5mg/m ³, far below the occupational health and safety standard (OEL 10mg/m ³), fundamentally solving the environmental and health hazards of dust generated by powdered MCA feeding.

-Accurate measurement adapted to automated production line: The granular form has excellent flowability and a resting angle of ≤ 28 °. It can be directly fed accurately through a weight loss feeder, with a measurement error of ≤± 0.5%. Compared with powdered products, the measurement accuracy is improved by 80%, avoiding flame retardant performance fluctuations caused by uneven feeding and ensuring product consistency in large-scale production.

2. Extraordinary liquidity and precise measurement

·Fluid like flowability: Particle sphericity>0.85, Hall flowability index better than 15, angle of repose<28 °. Its flow characteristics are comparable to engineering plastic pellets, and it can smoothly fall in the silo, completely avoiding the common "bridging" and "rat hole" phenomena of powder, providing stable and reliable raw material input for weight loss feeding systems and volume measurement systems.

·High packing density: The packing density reaches 0.70-0.90 g/cm ³, which is 1.5-2 times that of ordinary powdered MCA. This means lower transportation and storage costs per unit volume, smaller space occupied by silos, and higher production efficiency.

3. Coating modification optimization, balancing processing performance and mechanical properties

-Adopting environmentally friendly polyethylene wax coating technology: constructing a lubricating protective film on the surface of particles, which not only improves the interface compatibility with polymer substrates, but also improves the melt flow during processing. In the glass fiber reinforced PA66 system, the melt flow rate (MFR) is increased by 15%, and the extrusion process does not stick to the mold or block the mesh, making it suitable for high-speed automated production lines.

-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 or volatile gas release, ensuring that the product has no bubbles or warping defects.

-Controllable loss of mechanical properties: particles are uniformly dispersed and gradually melted during the mixing process, and the "cutting effect" on the substrate is smaller than that of traditional powder products. The retention rate of notch impact strength in PA6 products is ≥ 90%, and the retention rate of fracture elongation in PE cable materials is ≥ 88%, perfectly balancing flame retardant performance and material structural strength.
