Q1: What distinguishes MARTINAL OL-104LEO from other aluminum hydroxide flame retardants?
A: MARTINAL OL-104LEO is a surface-treated, low-dusting grade optimized for enhanced dispersion and compatibility in demanding polymer systems—particularly in thin-walled or high-gloss applications where particle agglomeration and surface defects are critical concerns.
Q2: Is MARTINAL OL-104LEO suitable for halogen-free flame-retarded polyolefins?
A: Yes—it is widely used in halogen-free flame-retarded PP and PE compounds, where its controlled particle size distribution and surface modification support good mechanical property retention and process stability during extrusion and injection molding.
Q3: How does the surface treatment affect processing and final part performance?
A: The proprietary surface treatment improves interfacial adhesion between the filler and polymer matrix, reducing viscosity buildup during compounding and contributing to better impact strength, surface finish, and long-term thermal stability in finished parts.
Q4: Can MARTINAL OL-104LEO be used in wire & cable jacketing formulations?
A: Yes—it is commonly incorporated into low-smoke, zero-halogen (LSZH) thermoplastic and thermoset compounds for wire & cable applications, supporting UL 1581 and IEC 60332-3 compliance when formulated with appropriate resin systems and synergists.
Q5: What handling precautions should be observed during storage and feeding?
A: Store in a cool, dry environment away from moisture and direct sunlight. Due to its low-dusting design, it exhibits improved flowability and reduced airborne particulate generation—but standard industrial hygiene practices for fine mineral powders should still be followed during handling and dosing.
