Melamine cyanurate (MCA) is a salt synthesized from melamine and cyanuric acid. It belongs to a series of ammonia flame retardants. When the flame retardant polyamide burns with the product, the carbon foam layer will protect the polymer and insulation. The smoke density and toxic gas of the polymer can be greatly reduced with the addition of the product, and no irritating toxic gas is produced.
Product features and advantages:
1. MCA is a halogen-free environment-friendly flame retardant. Its appearance is white crystalline powder, insoluble in water, soluble in ethanol, formaldehyde and other organic solvents. It is weakly acidic and can be well dispersed in oil medium.
2. Chemical properties are very stable, non-toxic, tasteless, environmental protection; good flame retardant effect, processing smoke is small.
3. Compared with the halogen / antimony flame retardant series, the heat stability is better. When heated at 300 ℃ for a long time, the heat loss is very low.
1. Flame retardant. This product is widely used in rubber, nylon, phenolic resin, epoxy resin, acrylic emulsion, polytetrafluoroethylene resin and other olefin resins as halogen free flame retardant components. It is especially suitable for electrical and electronic devices (connectors, switches, enclosures, etc.) made of polyamide or TPU. Its flame retardant effect can reach UL94V-0 in unfilled compounds or mineral filled compounds. It can also reach UL94V-2 in glass fiber filling system.
2. Coating matting agent. Good adhesion with resin, not easy to fall off and cause pollution. It is better than titanium dioxide and silica gel as chemical fiber matting agent.
3. Electroplating grade plastic additives. Adding nylon plastics to enhance the adhesion during electroplating.
