Melamine Cyanurate MC-G (Granular, 0.6–3mm)
Número CAS: 37640-57-6
MC-G is the granular grade of Melamine Cyanurate (MCA), offering the same halogen-free flame-retardant performance as MC-25 fine powder in a 0.6–3 mm granular form. The granular format dramatically reduces dust generation during handling and compounding, improving workplace safety and operator comfort. Bulk density ≥0.6 g/cm³ (twice that of powder grades) improves volumetric feeding accuracy and reduces hopper bridging. MC-G is specifically designed for older vertical-feed granulation equipment where fine powders cause feeding inconsistencies or die-face contamination. It delivers equivalent flame-retardant efficacy to MC-25 while offering significantly easier material handling. Applications include PA6, PA66, and PBT engineering plastic FR compounds. Achieves UL 94 V-0 at 1.6 mm in PA6 at 12–14% loading and PA66 at 10–12% loading. ROHS and EU REACH registered.
