Melamine Cyanurate

Melamine cyanurate (M C A) is a kind of salt synthesized from melamine and cyanuric acid, and belongs to nitrogen-containing flame retardant. Two types (powdered and granulated) of MCA can be supplied to meet the users’ requirements. When MCA decomposes ,It can liberate a large amount of inert gases to dilute oxygen and the fuel gases present at the point of combustion ,and absorb a large quantity of heat. In addition, MCA can accelerate the char-forming of the flame-retarded polymers. In this case, there are three type actions of flame retardant mechanisms.

Melamine Cyanurate is a halogen-free flame retardant for polyamide. Melamine Cyanurate has established itself as the flame retardant of choice to achieve UL94 V-0 especially for unfilled polyamide 66. Some of its attributes include cost effectiveness, excellent electrical and mechanical properties ,colorability, Non-blooming, low smoke generation, and low corrosivity. It is also a safe material to use from a handling standpoint, as well as in fire situations in compounds, health, safety, and compatible with environment. A good balance between flame-retardant effectiveness and thermal stability of Melamine Cyanurate provides for easy processing at the compounding stage.
