Melamine Hydrobromide Main Use:
Melamine Hydrobromide is primarily suitable for various flame-retardant PP materials, particularly those based on PP homopolymers and copolymers. This class of products is characterized by a low required dosage—typically just 1–2%—and eliminates the need for additional antimony trioxide; furthermore, it exhibits excellent resistance to blooming and migration. It serves as an ideal flame retardant for a wide range of flame-retardant PP products, including European-style sockets, automotive corrugated tubing, hollow boards, electrical component frames, automotive connectors, mining-grade PP sheets, and heater housings.
The PP flame retardant formulated with this melamine hydrobromide compound exhibits the following characteristics:
1. Low addition rate: When added at a concentration of just 1.5% in homopolymer PP, the flame retardancy rating can achieve UL94 V2 classification (at thicknesses of 3.2mm, 1.6mm, and 0.8mm).
2. Compatibility with fillers: It allows for the incorporation of 10–20% inorganic fillers, such as talc powder and barium sulfate.
3. Antimony-free: It requires no addition of antimony trioxide and contains absolutely no heavy metals.
4. Excellent stability: It exhibits no blooming or migration issues, possesses excellent light and thermal stability, and results in a smooth, pure-white surface finish with high gloss.
5. Halogen-free: It contains no organic bromine compounds and fully complies with SGS and REACH testing standards.
6. Minimal impact on transparency: It has virtually no adverse effect on transparency, making it suitable for use in transparent flame-retardant PP products and serving as a substitute for raw materials—such as PA6—that typically meet the V2 flame retardancy standard.
