Albemarle Magnifin H5IV H10 IV Aluminum Hydroxide Flame Retardant – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Magnifin H5IV and H10 IV in polymer formulations?

A: Magnifin H5IV and H10 IV are surface-treated aluminum hydroxide grades designed to act as halogen-free flame retardants and smoke suppressants. They decompose endothermically upon heating, releasing water vapor that cools the substrate and dilutes flammable gases — helping polymers meet key fire safety requirements without compromising processability or mechanical performance.

Q2: How do the H5IV and H10 IV variants differ in application suitability?

A: H5IV offers a finer particle size distribution and higher specific surface area, making it especially suitable for applications requiring superior dispersion and enhanced flame retardancy in thin-section or high-clarity compounds — such as wire & cable jackets and thermoplastic elastomers. H10 IV provides a slightly coarser, more robust particle morphology, offering improved flow and packing characteristics in high-loading applications like rigid PVC profiles and engineering thermoplastics.

Q3: Are these grades compatible with common polymer processing methods?

A: Yes — both H5IV and H10 IV are engineered for compatibility with extrusion, injection molding, and calendering. Their proprietary surface treatment enhances interfacial adhesion with non-polar and semi-crystalline polymers (e.g., polyolefins, PVC, TPEs), supporting stable melt flow and reduced agglomeration during high-shear processing.

Q4: Do Magnifin H5IV and H10 IV require additional synergists to achieve target flame performance?

A: These grades are effective as standalone flame retardants in many formulations, particularly where moderate fire resistance is required. However, for demanding standards (e.g., UL 94 V-0 at thin wall sections or improved tracking resistance), they are often combined with synergists such as zinc borate or melamine polyphosphate — the choice depending on the polymer matrix and regulatory environment.
