In the global trend of halogen-free flame retardant and functional additive industry upgrading, melamine cyanurate (MCA) has become the preferred functional additive for high-end materials such as nylon, polyurethane, elastomers, wires and cables, electronic appliances, etc. due to its core characteristics of halogen-free, low smoke, non-toxic, excellent thermal stability, and outstanding flame retardant efficiency.

In the production, mixing, and packaging processes of flame retardants, the issue of dust is not simply a cleaning challenge, but a systematic engineering problem related to process safety, product quality control, occupational health, and environmental compliance.

Against the backdrop of increasingly strict environmental regulations and constantly improving standards in the electrical, electronic, and automotive industries, halogen-free flame retardancy of nylon (polyamide) materials has become an inevitable trend.

Stepping into Taixing Shares’ zinc borate production workshop, one witnesses a seamless flow of operations—from feeding, synthesis, and pressure filtration to flash drying. Finished products are stacked neatly, the production line runs at full capacity, and amidst the roar of machinery, an atmosphere of intense, bustling energy permeates every corner.

Nylon (PA6/PA66/PPA), as the core category of engineering plastics, has shifted its flame retardant scheme from traditional halogen based to nitrogen based, phosphorus based, phosphorus nitrogen synergistic and other environmentally friendly systems.

In the technological path of flame retardancy of polymer materials, inorganic flame retardant fillers have become the mainstream choice to replace traditional halogenated flame retardants due to their outstanding advantages such as environmental friendliness, low smoke and low toxicity, and high thermal stability.
