Low Smoke Zero Halogen (LSZH) are widely used for safety cable applications. These compounds are typically based on polyolefins with a high loading of inorganic hydrated flame-retardant minerals such as ATH (Aluminum Trihydroxide) and MDH (Magnesium Hydroxide), which help reduce flame propagation, smoke generation, and toxic gas emissions during combustion.

To achieve high ATH/MDH loading while maintaining good mechanical and processing properties, PA-Bond Coupling Agent can be incorporated into the LSZH compound. It improves the interfacial adhesion and compatibility between the polyolefin matrix and ATH/MDH fillers, resulting in better filler dispersion, improved tensile and elongation properties, smoother surface appearance, and more stable processing.
