B1 Irradiation Cross-linked LSZH Flame Retardant Jacket Material

Low Smoke Zero Halogen B1 Cable Material

Irradiation cross-linked low-smoke HFFR B1 cable material is made of high-purity resin as the base material, with halogen-free flame retardant, cross-linking agent, antioxidant, etc. mixed and extruded into granules. It has excellent properties such as halogen-free, heat-resistant, flame-retardant, low-smoke, and weather-resistant. It has no precipitation pollution, meets the relevant requirements of Rohs, and is easy to extrude and process.

Application：wire and cable for construction.

B1 cable material is a high-performance cable material. It produces less smoke when burning and does not contain halogen, so it does not produce toxic gases. It is particularly suitable for occasions with high safety and environmental protection requirements, such as subways, high-rise buildings, ships, oil platforms, etc.

The Preparation of This Material Usually Includes The Following Steps

Raw material mixing: EVA resin, linear low-density polyethylene, maleic anhydride grafted linear low-density polyethylene, modified halloysite nanotubes, modified magnesium hydroxide, polyphosphate flame retardant, antioxidant, lubricant and other raw materials are mixed evenly in a certain proportion.

Melt extrusion: Use a twin-screw extruder for melt extrusion granulation to obtain cable sheath material.

Irradiation cross-linking: Through electron beam irradiation, the cross-linking degree of the material is increased, and its mechanical properties and heat resistance are enhanced.

Characteristics of Radiation Cross-linked Low Smoke HFFR Insulation B1 Cable Material

High flame retardancy: It can meet the B1 flame retardant standard and has excellent flame retardant properties.

Good mechanical properties: Both tensile strength and elongation at break reach a high level.

Excellent processing performance: It exhibits good process performance during cable extrusion.

This material has a wide range of applications and can be used to prepare various wire or cable sheaths, especially those that require high flame retardant properties and environmental protection characteristics. With the improvement of environmental protection and safety requirements, the demand for B1 radiation cross-linked low-smoke halogen-free flame retardant sheath materials is expected to increase further。
