ML-H9001A/B/C 90℃ Halogen-Free Low Smoke Flame Retardant Class A Sheath Compound

The ML-H9001A/B/C series is a high-performance, thermoplastic Low Smoke Zero Halogen (LSZH) sheath compound and masterbatch engineered specifically for wire and cable insulation and jacket applications. Designed to meet the stringent Class A flame retardancy standards, this material is formulated using advanced polyolefin resins combined with high-purity inorganic flame retardants. It operates reliably at a continuous temperature of 90℃, maintaining its mechanical integrity and electrical insulation properties under thermal stress. In the event of a fire, the compound produces minimal smoke density and zero corrosive halogen acid gases, significantly improving visibility and safety in enclosed environments. The ML-H9001 series provides a balanced profile of extrusion stability, oil resistance, and mechanical toughness, facilitating high-speed production on standard extrusion lines.

ML-H9001A/B/C 90℃ Halogen-Free Low Smoke Flame Retardant (LSZH) Class A Sheath Compound

Core Advantages

Flame Propagation Control: Achieves Class A rating in vertical bundle flame tests, effectively inhibiting the spread of fire along cable runs.

Environmental Safety: Zero halogen content ensures no toxic or corrosive gases (such as HCl) are released during combustion, protecting both human life and sensitive electronic equipment.

Thermal Stability: Rated for long-term operation at 90℃, exceeding the performance of standard 70℃ LSZH compounds.

Optimized Processability: Controlled rheological properties ensure a smooth surface finish and consistent diameter during high-speed cable extrusion.

Application Scenarios

Public Infrastructure: Used in subway systems, railway stations, and airport terminals where low smoke emission is mandatory for evacuation safety.

High-Rise Construction: Applied as sheathing for power cables, control cables, and data cables in commercial and residential skyscrapers.

Data Centers and Telecommunications: Protects fiber optic and copper cabling systems while preventing corrosive damage to servers during thermal incidents.

Marine and Offshore: Suitable for shipboard wiring and offshore platforms requiring Class A flame retardancy and moisture resistance.

Storage and Handling Guidelines

Moisture Control: LSZH materials are hygroscopic. Store in a dry, ventilated warehouse. If the package is opened or stored for an extended period, the compound must be pre-dried at 65-75℃ for at least 2-4 hours before extrusion.

Temperature Regulation: Avoid exposure to direct sunlight or temperatures exceeding 35℃ during storage to prevent premature aging or agglomeration of the pellets.

Extrusion Parameters: Recommended extrusion melt temperature ranges between 150℃ and 175℃. Avoid excessive shear heat or temperatures above 180℃ to prevent the decomposition of inorganic flame retardants.

Packaging Integrity: Ensure pallets are kept stable and moisture-proof liners remain sealed until the point of use to maintain the specified dielectric properties.
