Thermoplastic LSZH Flame Retardant Polyolefin Insulating Compound

Thermoplastic LSZH Flame Retardant Polyolefin Insulating Compound

Product Description

Based on polyolefin, containing special halogen-free flame retardant and smoke suppressant, it is processed by precise mixing with special formula. Its flame retardant system has excellent flame retardant, wire can pass a single vertical combustion test . When burning, no halogen acid gas is released, the amount of toxic and corrosive gas is very small, and the smoke concentration is very low. Moreover, its hardness is relatively high, which is suitable for BV wire for construction.

1. Standard: GB/T32129-2015

2. LSZH Cable Jacket Features and uses

This product not only has excellent low-smoke halogen-free flame retardant performance, but also has excellent extrusion processing performance. It can be extruded on an ordinary PVC extruder. As long as the cooling device is normal, the extrusion processing speed can be accelerated. And its high hardness can avoid surface wear caused by drag, friction, etc. during the laying process, which affects the quality of products, especially BV lines for construction. This product is suitable for occasions with high flame retardant requirements and low secondary hazards, such as: subways, ships, high-rise building program-controlled switch rooms, computer rooms and various crowded public places. It is suitable for the insulation layer of low-smoke halogen-free flame-retardant cables with a core working temperature of 90 °C.

3. Extrusion process

It can be extruded by L/D18-25 extruder. When the screw compression ratio is low, the output volume is large. Each zone of the extruder must have a cooling control system, and the melt temperature should not exceed 170 °C. Since the difference between the actual temperature of the melt and the indicated value of the temperature control table varies with the type of extruder, each user should select a suitable temperature according to the specific conditions of the extruder used.
