#CAIPerformance Additives, a global provider of advanced polymer additive technologies, announced the launch of ST-MCA-H.
ST-MCA-H is a high-efficiency, halogen-free flame retardant engineered to deliver UL-94 V-0 performance at significantly lower loadings in nylon applications.
Offering reduced risk of blooming and migration in applications
Designed for unfilled PA6 and PA66, ST-MCA-H enables compounders to meet flame-retardancy targets while preserving mechanical properties, reducing density, and simplifying formulation design.
ST-MCA-H is a high-activity melamine cyanurate–based #flameretardant optimized for superior dispersion in #polyamides. Its nitrogen-rich structure provides effective flame suppression through endothermic heat absorption, gas-phase nitrogen release, and stable char formation, resulting in reliable flame retardancy without halogens or heavy-metal synergists.
Improved dispersion efficiency allows ST-MCA-H to outperform conventional MCA grades that require substantially higher loadings. In unfilled PA6 and PA66 formulations, ST-MCA-H achieves UL-94 V-0 ratings at 0.8 mm, 1.6 mm, and 3.0 mm thicknesses at typical loadings of 5% in PA6 and 4% in PA66. Compared with standard MCA, this lower dosage helps maintain toughness, reduce the risk of blooming or migration, and improve overall compound competitiveness in demanding electrical and electronic applications.
