The evolution of wire and cable technology demands materials that offer not only excellent electrical insulation and mechanical robustness but also enhanced safety features. Low Smoke Zero Halogen (LSZH) cables are a prime example, designed to minimize smoke and toxic gas emissions in the event of a fire. At Ningbo Inno Pharmchem Co., Ltd., we play a crucial role in enabling these advanced applications through our specialized polyethylene (PE) coupling agents.

LSZH cable compounds typically incorporate a high loading of mineral-based flame retardants, such as aluminum hydroxide (ATH) or magnesium hydroxide (MDH), into a PE or ethylene copolymer matrix. These fillers are essential for achieving the desired flame retardant properties. However, incorporating high levels of inorganic fillers into a non-polar polymer like PE can lead to significant challenges in processing and performance. The fillers tend to agglomerate, leading to poor dispersion, increased melt viscosity, and a detrimental impact on the mechanical properties of the cable insulation.

This is where our coupling agent for LSZH cable applications becomes indispensable. Our anhydride-modified PE coupling agents are specifically designed to address these challenges. By acting as an adhesion promoter between the polar inorganic fillers and the non-polar PE matrix, these agents significantly improve the dispersion of the flame retardant additives. This leads to a more homogenous compound, easier processing, and enhanced mechanical properties for the final cable product.

The benefits are multi-fold: improved tensile strength and elongation at break, better impact resistance, and a more consistent performance profile for the LSZH cable. Furthermore, by promoting better filler-polymer interaction, these coupling agents can help maintain the overall integrity and flexibility of the cable insulation, even under demanding environmental conditions.

Ningbo Inno Pharmchem Co., Ltd. is committed to providing innovative plastic auxiliary agents that meet stringent industry standards. Our expertise in developing coupling agent for PE compounds ensures that manufacturers can produce high-quality LSZH cables that comply with safety regulations while offering excellent performance. We understand the critical importance of reliable adhesion and filler dispersion in these applications, and our products are engineered to deliver precisely that.

By partnering with us, wire and cable manufacturers can leverage our advanced PE coupling agents to create safer, more reliable, and higher-performing LSZH cables, contributing to improved safety in buildings, transportation, and various industrial environments.
