Q1: What are the key advantages of MARTINAL ON-908 compared to other aluminum hydroxide flame retardants?
A: MARTINAL ON-908 is engineered for enhanced dispersion and compatibility in polymer systems, particularly in thermoplastics and elastomers. Its optimized particle size distribution and surface treatment support improved mechanical property retention after compounding, reduced viscosity during processing, and more uniform flame-retardant performance across diverse formulations.
Q2: Is MARTINAL ON-908 suitable for halogen-free flame-retardant cable compounds?
A: Yes — MARTINAL ON-908 is widely used in halogen-free low-smoke zero-halogen (LSZH) cable jacketing and insulation compounds. It contributes to effective flame suppression and smoke suppression while maintaining good processability and long-term stability under typical extrusion conditions.
Q3: How does moisture sensitivity affect handling and storage of MARTINAL ON-908?
A: As with most aluminum hydroxides, MARTINAL ON-908 is hygroscopic and should be stored in a cool, dry environment with sealed packaging to prevent moisture uptake. Prolonged exposure to high humidity may impact dispersion efficiency and require pre-drying before high-shear compounding — consult your processing guidelines for best practices.
Q4: Can MARTINAL ON-908 be used in polyolefin-based automotive interior materials?
A: Yes — it is commonly incorporated into PP and PE-based automotive interior components where UL 94 V-0 or V-1 ratings are required. Its thermal decomposition profile aligns well with polyolefin processing windows, and its surface modification helps preserve melt flow and impact resistance in thin-wall applications.
