Nylon Flame Retardant MCA

Universal flame retardants face pain points such as poor compatibility with nylon, high additive degradation of mechanical properties, and unstable flame retardant efficiency. The nylon flame retardant MCA produced by Taixing innovatively adopts the core technology of nylon molecular chain compatibility modification and crystal orientation regulation, and constructs a three in one nylon exclusive flame retardant system of "gas phase dilution catalytic carbonization interface anchoring". With a nitrogen content of ≥ 59%, only 8% -18% addition is needed to achieve a 1.6mm thickness UL 94 V-0 flame retardant for nylon materials, completely solving the industry problems of "poor adaptability, large performance loss, and low batch stability" of traditional flame retardants, and providing a cost-effective exclusive solution for global nylon modification enterprises.

Core strengths

1. Nylon exclusive compatibility modification, with excellent interface adhesion and dispersibility

-Innovative Nylon Grafting Compatibility Coating Technology: Active functional groups that match the molecular structure of nylon are grafted onto the surface of MCA particles to form an "interface anchoring" effect, improving compatibility with nylon substrates by 80%. This solves the problem of aggregation and precipitation of universal MCA in nylon, and achieves micrometer level dispersion uniformity in the glass fiber reinforced PA66 system.

-Directional crystal shape control ensures stable performance: By using crystal shape induction technology to optimize the MCA crystal structure, it does not undergo crystal shape transformation during nylon melt processing, and the flame retardant efficiency deviation between batches is ≤± 2%, ensuring the consistency of modified nylon product performance.

-Compatible with all types of nylon systems: It is compatible with pure PA6, PA66, PA12, as well as modified nylon systems such as fiberglass reinforcement, toughening, mineral filling, etc., without the need to adjust the formula system, greatly reducing the R&D and production threshold for modified enterprises.

2. Triple synergistic flame retardant mechanism, efficiently blocking the combustion process of nylon

-Building a nylon exclusive flame retardant protective net: In high temperature environments above 320 ℃, MCA molecules absorb heat and decompose, releasing high concentrations of nitrogen and water vapor, rapidly diluting the combustible gases produced by nylon combustion; The decomposition products catalyze the dehydration and cross-linking of nylon molecular chains, forming a dense and strongly adhesive carbon layer that blocks oxygen and heat transfer; At the same time, it undergoes a synergistic reaction with the amide bond of the nylon matrix to suppress the droplet phenomenon and fundamentally prevent flame spread.

-Low addition amount achieves efficient flame retardancy: adding 10% to pure PA6 system can achieve UL 94 V-0 level; By adding 15% to the 30% fiberglass reinforced PA66 system, the flame retardant grade can still reach V-0 level, which is 25% less than the general MCA addition and significantly reduces the formulation cost.

-Zero halogen, low smoke, low toxicity and environmental protection properties: There is no release of toxic gases such as hydrogen halides and dioxins during the combustion process. The smoke density (DS, 4 minutes) is ≤ 140, 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.
