Huber Magnifin H-7 Magnesium Hydroxide
Categories:	Ceramic; Oxide; Magnesium Oxide; Other Engineering Material; Additive/Filler for Polymer
Material Notes:	MAGNIFIN H-7 is a high-purity magnesium hydroxide. Based on a mineral raw material, the patented process guarantees a regular structure of the crystallite. MAGNIFIN H-7 conforms to the European Pharmacopeia. MAGNIFIN H-7 is tailor-made for plastic and elastomer applications and represents a halogen free flame retardant with low smoke emission and high thermal stability up to 340°C. During the decomposition process no toxic or corrosive gases are generated. CAS No.: 1309-42-8 EC/EINECS No.: 215-170-3 Information provided by J.M. Huber Corporation
