Quaternary Ammonium-Modified Organic Montmorillonite Charring Agent ZF-C-320

ZF-C-320 is a quaternary ammonium-modified, high-purity organic montmorillonite widely applicable to polymer systems such as thermoplastic or cross-linked polyolefins, elastomers, and engineering plastics. It exhibits excellent char-forming and self-extinguishing properties; at high temperatures, it rapidly forms a stable char layer that effectively isolates oxygen and retards the combustion process, thereby enhancing the material's flame retardancy. Furthermore, it possesses excellent dispersibility and processing characteristics, exerting minimal impact on the physical and mechanical properties of the final product.

ZF-C-320 is a high-purity organic montmorillonite modified with quaternary ammonium salt intercalants, engineered as a mineral charring agent for intumescent halogen-free flame-retardant systems.

The product appears as a soft off-white powder with Hunter whiteness of ≥90, density of 2–2.5 g/cm³, and a median particle size (d50) of 15–18 μm with moisture content ≤5.0%. The 2:1 layered crystal structure creates a tortuous path during combustion that slows gas diffusion and heat penetration, forming a dense, thermally stable char layer that insulates the underlying polymer and limits oxygen ingress. Char quality is excellent — rapid formation and self-extinguishing behaviour characterise ZF-C-320 in end-use fire tests.

Effective at low loading levels, typically 2–10 wt%, ZF-C-320 provides dual functionality: charring performance alongside mechanical reinforcement through platelet morphology. The organic modification supports compatibility with polyolefin and styrenic matrices, enabling effective intercalation during melt compounding.

Good dispersibility and processing characteristics ensure minimal impact on the mechanical properties of the finished compound. Suitable for thermoplastic and crosslinked polyolefins, elastomers, and engineering plastics in applications targeting IEC, UL, or EN fire performance standards.
