Product introduction:

Melamine cyanurate (MCA for short) is a salt synthesized from melamine and cyanuric acid, which belongs to ammonia series flame retardant. When the flame retardant polyamide of this product is burned, the carbon foam layer formed protects the polymer and insulates oxygen. With the addition of this product, the smoke density and toxic gases of the polymer can be greatly reduced without producing irritating toxic gases.

Product features and excellence:

1, MCA is a halogen-free flame retardant, the appearance of white crystalline powder, insoluble in water, soluble in ethanol, formaldehyde and other organic solvents; weak acid, can be better dispersed in oil media.
2, the chemical properties are very stable, non-toxic, tasteless, environmental protection; good flame retardant effect, small smoke processing.
3. The addition amount is relatively low, and the thermal stability is good compared with the halogen/antimony flame retardant series. Long-term heating at 300°C, its heat loss is very low.

Product use:

1, flame retardant. The product is widely used in rubber, nylon, phenolic resin, epoxy resin, acrylic emulsion, polytetrafluoroethylene resin and other olefin resin as halogen-free flame retardant components. Especially suitable for electrical and electronic devices (connectors, switches, housings, etc.) made of polyamide or TPU, in unfilled compounds or mineral-filled compounds, the flame-retardant effect can reach the UL94V-0 level. In the glass fiber filling system, it can also reach the UL94V-2 level.
2. Coating matting agent. Good adhesion with resin, not easy to fall off and cause pollution. It is better than titanium white and silica gel as a chemical fiber matting agent.
3. Plating grade plastic additives. Incorporated into nylon plastic to enhance adhesion during electroplating.
