Frequently Asked Questions (FAQ) about Melamine Cyanurate
Q1: What is Melamine Cyanurate commonly used for?
A1: Melamine Cyanurate is mainly used as a halogen-free flame retardant in polyamides, especially PA6 and PA66. It provides excellent flame retardancy while maintaining mechanical properties, making it suitable for automotive parts, electronics, and engineering plastics.
Q2: How does Melamine Cyanurate work as a flame retardant?
A2: It releases non-flammable gases such as nitrogen when exposed to high temperatures. This dilutes oxygen around the material and forms a protective char layer, effectively slowing down combustion without producing harmful halogenated by-products.
Q3: Can Melamine Cyanurate be used in combination with other additives?
A3: Yes, it is often used with synergistic flame retardants like phosphates or other nitrogen-based compounds to achieve enhanced flame-retardant performance. This combination can help meet stricter fire safety standards while maintaining cost efficiency.
Q4: Is Melamine Cyanurate environmentally safe?
A4: Absolutely. It is halogen-free, non-toxic, and does not release corrosive or harmful gases during combustion. This makes it a preferred choice for manufacturers seeking compliance with environmental regulations such as RoHS and REACH.
Conclusion
Melamine Cyanurate is a proven, effective, and eco-friendly flame retardant solution that supports industries requiring high-performance safety materials. With strong thermal stability, halogen-free properties, and compatibility with engineering plastics, it is widely adopted across multiple sectors.
