Q1: What distinguishes Martinal OL-104 S from other aluminum hydroxide flame retardants?
A: Martinal OL-104 S is a surface-treated, ultrafine aluminum hydroxide grade optimized for high-loading applications in thermoplastics and elastomers. Its proprietary surface treatment enhances dispersion stability and interfacial compatibility with non-polar polymers, supporting improved mechanical properties and reduced viscosity compared to standard untreated grades.
Q2: Is OL-104 S suitable for halogen-free flame-retarded polyolefin compounds?
A: Yes — OL-104 S is specifically engineered for use in halogen-free flame-retarded polyolefins such as PP and PE. Its fine particle size and tailored surface chemistry promote uniform dispersion and support V-0 or V-1 ratings in UL 94 tests when incorporated at appropriate loading levels.
Q3: How does OL-104 S affect processing behavior during extrusion or injection molding?
A: Due to its optimized particle morphology and surface treatment, OL-104 S typically exhibits lower melt viscosity impact and reduced screw torque demand compared to conventional aluminum hydroxides. This supports smoother extrusion and improved mold filling, especially in high-load formulations.
Q4: Can OL-104 S be used in wire & cable jacketing compounds?
A: Yes — OL-104 S is widely applied in low-smoke, zero-halogen (LSZH) wire and cable compounds. Its high purity, controlled particle size distribution, and thermal stability contribute to consistent flame performance and reduced smoke density during combustion.
