The Importance of Extrusion Process for LSZH Polyolefin Compound: SUNUA’s Best Performance

When it comes to selecting materials for cables and wires, performance is everything. One key factor in determining the quality of a cable is the extrusion process used to manufacture it. For LSZH polyolefin compounds, the extrusion process can significantly impact the material’s properties, from its mechanical and physical characteristics to its flame retardancy. At the forefront of LSZH polyolefin compound production is SUNUA, a national high-tech enterprise with a focus on developing and producing new polymer materials for cables and wires. In this blog, we’ll dive into why the extrusion process is so important for LSZH polyolefin compounds, and why SUNUA’s process leads to superior performance.

Extrusion Process of SUNUA LSZH Polyolefin Compound

SUNUA’s LSZH polyolefin compound can be extruded by L/D18-25 extruder. The screw compression ratio is low, which leads to a large output volume. It’s essential to have a cooling control system for each zone of the extruder, and the melt temperature should not exceed 180 °C. However, the difference between the actual temperature of the melt and the indicated value of the temperature control table varies with the type of extruder. Therefore, each user should select a suitable temperature according to the specific conditions of the extruder used.

Why SUNUA’s Extrusion Process has the Best Performance

SUNUA’s LSZH polyolefin compound has the best performance due to its advanced extrusion process. The low screw compression ratio and large output volume help to enhance the production efficiency, making it a cost-effective solution for manufacturers. The cooling control system in each zone ensures that the melt temperature does not exceed 180 °C, reducing the risk of overheating and degradation of the compound. Moreover, the compound’s excellent cable-forming technology ensures that it can be molded into different shapes and sizes to meet different application needs.


In conclusion, the extrusion process is a critical factor in determining the performance of LSZH polyolefin compound. SUNUA’s LSZH polyolefin compound has the best performance due to its advanced extrusion process, which enhances production efficiency, reduces the risk of overheating and degradation, and ensures excellent cable-forming technology. If you’re looking for LSZH material for your application needs, SUNUA is the best choice.
