Thermoplastic LSZH Flame Retardant Polyolefin Insulating Compound

Model: SHD01-J-01

Thermoplastic granules 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.To save your time, contact us for specific items & details you may interest.

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.

At SUNUA, we prioritize providing customers with reliable cable compounds at competitive prices. Our range includes flame retardant polyethylene and LSOH LSZH compound, among others.

1. Standard:

GB/T32129-2015

2. LSZH Cable Jacket Features and uses

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.

The following temperatures can be used as a reference for commissioning:

The machine head can be without a filter screen, or a filter screen below 60 mesh can be used; the mold can be squeezed or squeezed. It can be matched with special color masterbatch, the dosage is about 1-2%, generally does not affect the material properties

Note: If the aluminum-plastic composite inner bag’damp proof fails, it should be dried before use. The drying temperature should be 65℃ and the drying time should be at least 2 hours. It is better for hot material to enter and leave the extruder.

4. Packaging, transportation and storage

Packing: N.W: 25kg/1000kg bags with inner bag of aluminum-plastic composite vacuum moisture-proof bag and outer packing being made of kraft paper composite bag or woven bag.It should not be exposed to the sun and rain during transport. It should be stored in a clean, cool, dry and ventilated warehouse. It should be handled with care.

5. Shelf life :

6 months
