High Purity MCA

Ordinary MCA faces pain points such as "performance fluctuations caused by insufficient purity, compliance risks caused by excessive impurities, poor compatibility, and degradation of product quality". The high-purity MCA flame retardant produced by Taixing innovatively adopts the core technology of multi-stage recrystallization purification and molecular level interface modification, which increases the purity of the product to over 99.8% and the nitrogen content to ≥ 59.5%. It constructs a dual efficient flame retardant system of "gas-phase dilution catalytic carbonization", and can achieve a 1.6mm thickness UL 94 V-0 flame retardant with only 8% -18% addition, completely solving the industry problem of "low purity, mixed performance, and difficult adaptation to high-end scenarios" of traditional MCA. It provides a core material solution that combines ultimate purity and efficient flame retardant for the global high-end manufacturing industry.

Core strengths

1. Ultra pure process control, impurity content approaching zero

-Innovative four level recrystallization+precision membrane filtration+vacuum degassing combined purification process, breaking through the purity bottleneck of traditional purification technology. The main content of MCA in the product is ≥ 99.8%, residual free cyanuric acid is ≤ 0.05%, and free melamine is ≤ 0.001%, effectively eliminating risks such as electronic component short circuit and medical material sensitization caused by impurity migration.

-Ultimate impurity control meets high-end standards: Through precise ICP-MS detection, the total content of heavy metals such as lead, mercury, cadmium, etc. is ≤ 0.3ppm, and the halogen content (Cl+Br) is ≤ 20ppm, far lower than the industry standard of ordinary MCA, fully meeting the "ultra clean" requirements of electronic and medical grade materials.

-High purity ensures performance stability: purity fluctuation between batches is ≤ ± 0.1%, flame retardant efficiency deviation is controlled within 3%, solving the problem of product performance fluctuation caused by uneven purity of ordinary MCA, and adapting to the standardized and refined production needs of high-end manufacturing.

2. Molecular level synergistic flame retardant, achieving efficient protection with low addition amount

-Constructing a molecular level flame retardant system of "inert gas dilution+ceramicized carbon layer barrier": Under high temperature environments above 320 ℃, high-purity MCA molecules decompose uniformly, releasing high concentrations of nitrogen and water vapor, rapidly diluting the concentration of combustible gases in the combustion zone; At the same time, the decomposition products undergo directional catalytic reactions with the substrate resin, forming a dense and strongly adhered ceramicized carbon layer that physically blocks oxygen and heat transfer, resulting in a 45% increase in flame retardant efficiency compared to ordinary MCA.

-Low addition amount balances flame retardancy and performance: adding 10% to the electronic grade PA66 system can achieve 1.6mm UL 94 V-0 grade, and when compounded with electronic grade aluminum phosphate, the addition amount can be reduced to 8%; Adding 12% to medical grade TPE material increases the limit oxygen index (LOI) to over 32% without precipitation or odor.

-Zero halogen, low smoke, and low toxicity characteristics: During the combustion process, there is no release of toxic gases such as hydrogen halides and dioxins. The smoke density (DS, 4 minutes) is ≤ 135, and the smoke toxicity reaches the highest safety level of EU EN 13501-1:2024. It is suitable for sensitive scenarios such as enclosed electronic devices and medical implant equipment peripheral components.

3. Interface modification and optimization, perfectly compatible with high-end processing technology

-Using electronic grade silane coupling agent (KH-560) molecular level coating modification: constructing an affinity layer on the surface of MCA particles that is compatible with high-end substrates, greatly improving the dispersion uniformity in electronic grade nylon and medical grade TPE, solving the problem of white spots and pockmarks caused by traditional MCA aggregation, and achieving a mirror level surface finish of the product.

-Narrow particle size distribution suitable for precision molding: The average particle size D50 is precisely controlled within 1-3 μ m, D98 ≤ 8 μ m, with excellent flowability and a resting angle of ≤ 30 °. It can be stored in a 60% humidity environment for 6 months without clumping, and can be directly used in high-end processes such as precision injection molding and semiconductor packaging without pre drying. It does not stick to the mold or block the mesh, ensuring the molding accuracy of thin-walled precision components (≤ 0.8mm).

-Excellent thermal stability over a wide temperature range: 1% thermal weight loss temperature ≥ 330 ℃, entering the rapid decomposition stage at 450 ℃, with a processing temperature window covering 260-350 ℃, which can match the high-temperature processing requirements of electronic grade PA66 and special engineering plastics. High temperature molding has no decomposition or volatile gas release, avoiding product bubbles and warping defects.
