Q1: What is the primary application area for Exolit EP CCL?
A: Exolit EP CCL is specifically developed for flame retardancy in polyolefin-based cable compounds, particularly low-smoke zero-halogen (LSZH) insulation and jacketing materials used in building wiring, data cables, and rail transport applications.
Q2: How does Exolit EP CCL achieve flame retardancy without halogens?
A: It functions via an intumescent mechanism—releasing non-flammable gases and forming a thermally insulating char layer upon exposure to heat—thereby suppressing flame spread and reducing smoke generation in compliance with halogen-free requirements.
Q3: Is Exolit EP CCL compatible with common polyolefin processing methods?
A: Yes—it is designed for compatibility with standard compounding techniques including twin-screw extrusion and is stable under typical polyolefin processing temperatures, supporting good dispersion and minimal plate-out during high-speed cable extrusion.
Q4: What are the key handling and storage recommendations?
A: Store in a cool, dry place in original sealed packaging to prevent moisture uptake; avoid prolonged exposure to ambient humidity prior to use, as it may affect dispersion performance in hydrophobic polymer matrices.
Q5: How does dosage affect mechanical properties in the final compound?
A: Due to its optimized particle morphology and surface treatment, Exolit EP CCL typically enables effective flame retardancy at relatively low loadings, helping preserve tensile strength and elongation—though optimal dosage depends on formulation requirements and target fire performance class.
