The wire and cable industry continuously seeks materials that offer enhanced safety, performance, and processing efficiency. Halogen-Free Flame Retardant (HFFR) compounds are increasingly specified for their reduced smoke and toxicity in fire situations. However, incorporating high loadings of inorganic flame retardant fillers, such as ATH (Aluminum Trihydrate) and MDH (Magnesium Hydroxide), into polyolefin matrices like LLDPE can lead to poor interfacial adhesion and consequently, degraded mechanical properties. This is where the role of coupling agents, particularly Maleic Anhydride Modified LLDPE (MAH-LLDPE), becomes indispensable. NINGBO INNO PHARMCHEM CO.,LTD. provides advanced solutions for this sector.

Maleic anhydride grafting onto LLDPE introduces polar functional groups onto the polymer backbone. These groups act as bridges, creating strong chemical bonds between the non-polar polyolefin matrix and the polar inorganic fillers. In HFFR compounds, MAH-LLDPE functions as an effective coupling agent for HFFR compounds, significantly improving the compatibility between the LLDPE matrix and the flame retardant additives.

When high levels of mineral fillers are present, they tend to agglomerate and weaken the polymer structure if not properly bonded. MAH-LLDPE facilitates the uniform dispersion of these fillers throughout the LLDPE matrix. This improved dispersion leads to a dramatic enhancement in mechanical properties such as tensile strength, elongation at break, and impact resistance. Without such a coupling agent, the final cable compounds would be brittle and prone to failure.

The application of maleic anhydride grafting in polymer modification is particularly beneficial in the wire and cable industry because it directly addresses the challenge of incorporating significant amounts of flame retardant fillers while maintaining the necessary physical and electrical properties of the cable insulation and sheathing. The enhanced adhesion ensures that the composite material can withstand the demanding conditions of cable manufacturing and end-use applications.

NINGBO INNO PHARMCHEM CO.,LTD. understands the critical performance requirements of the wire and cable sector. Our expertise in MAH modified polyethylene for extrusion allows us to supply tailored grades of MAH-LLDPE that optimize the performance of HFFR compounds.
