Micro Melamine Cyanurate (MCA)

The micro melamine cyanurate (MCA) produced by Taixing factory breaks the industry pain point of traditional MCA facing "high addition leading to mechanical property degradation and product appearance defects". Innovatively adopting the core technology of nanocrystal reconstruction and phosphorus nitrogen synergistic molecular design, a dual efficient flame retardant system of "gas phase inhibition condensed phase carbonization" is constructed, with a nitrogen content of ≥ 59.5%. With the addition of specialized synergists, UL 94 V-0 flame retardant can be achieved with only 3% -12% addition, completely solving the core problem of "high addition, low efficiency, and performance loss" in traditional products, and providing a flame retardant solution that combines safety, performance, and economy for the global high-end manufacturing industry.

Core strengths

1. Nanosynergistic technology, with trace addition to achieve efficient flame retardancy

-Innovative nanoscale precision granulation process: Through template induction directional growth technology, the MCA crystal particle size is stably controlled at 500nm-1 μ m, the specific surface area is increased to three times that of ordinary MCA, the contact area with the substrate is significantly increased, and the flame retardant activity is significantly enhanced.

-Phosphorus nitrogen synergistic amplification of flame retardant efficiency: The molecular structure integrates a nitrogen based gas source and a phosphorus based carbon source, forming a synergistic effect of "inert gas dilution+catalytic char barrier" at high temperatures, which increases the flame retardant efficiency by 40% compared to traditional MCA. Adding 8% to the PA6 system can achieve 1.6mm UL 94 V-0 grade, and adding 12% to the pure PE system can pass the IEC 60332-1 flame retardant standard.

-Significant increase in Limiting Oxygen Index: By adding 5% -10% to TPE, PBT and other substrates, the Limiting Oxygen Index (LOI) can be increased from 18% -22% of the substrate itself to 30% -35%, with a self extinguishing time of ≤ 2 seconds and no further ignition phenomenon.

2. Low addition advantage, perfectly retaining the intrinsic properties of the substrate

-The loss of mechanical properties tends to zero: the addition amount is reduced by 40% -60% compared to traditional MCA, and the "cutting effect" on the substrate is significantly weakened. The retention rate of notch impact strength in PA66 products is ≥ 95%, and the retention rate of fracture elongation in TPE materials is ≥ 92%, fully meeting the mechanical requirements of structural and precision components.

-Processing flowability is not affected: The synergistic effect of nanoscale particle size and specialized dispersing agents improves the dispersion uniformity in the substrate by 70%, reduces the melt flow rate (MFR) by ≤ 5%, and the injection molding process does not stick to the mold or block the mesh, making it suitable for the molding process of thin-walled precision products.

-The appearance of the product is defect free: it avoids the problems of "white spots, pockmarks, and frosting" caused by traditional high additive content. The surface smoothness of the product reaches mirror level, and it can be directly used in scenes with strict appearance requirements such as automotive interiors and high-end home appliance shells.

3. Wide temperature range stability, suitable for multiple high-end processing technologies

-Excellent thermal stability ensures processing safety: 1% thermal weight loss temperature ≥ 320 ℃, 450 ℃ before entering the rapid decomposition stage. The processing temperature window covers 240-350 ℃ and can be matched with high-temperature processing materials such as fiberglass reinforced PA66 and special nylon. High temperature forming has no decomposition and no volatile gas release.

-Outstanding weather and aging resistance: After 1000 hours of xenon lamp aging and 85 ℃/85% RH wet heat testing, the retention rate of flame retardancy and mechanical properties is ≥ 90%, with no moisture absorption clumping or energy decay, meeting the long-term service requirements of new energy vehicles and outdoor electronic equipment.

-Stable electrical performance: volume resistivity ≥ 10 ¹⁴Ω· cm, leakage tracking index (CTI) ≥ 650V, added without affecting the dielectric properties of the substrate, suitable for products with high insulation requirements such as high-voltage connectors and 5G base station components.

4. Green and environmentally friendly

-Extremely environmentally friendly and free of harmful substances: completely free of halogens, heavy metals, and polybrominated diphenyl ethers (PBDE), with halogen content (Cl+Br) ≤ 30ppm and total heavy metal content ≤ 0.5ppm.

-Low toxicity, safety, and no health risks: The oral LD50 of rats is greater than 5000mg/kg, which is an actual non-toxic material. The occupational exposure limit (OEL) is up to 10mg/m ³ (8-hour TWA). The production and use process is friendly to human health and the environment, and can be used for modifying food contact grade plastic products.

-Circular economy adaptability: After mechanical recycling of waste products, there is no residual pollution of flame retardant components, and the retention rate of flame retardant performance of recycled materials is ≥ 88%, which helps customers obtain green supply chain certification for their products and conforms to the global trend of "carbon neutrality".
