Huber Magnifin H-5 MV Magnesium Hydroxide
Categories:	Ceramic; Oxide; Magnesium Oxide; Other Engineering Material; Additive/Filler for Polymer
Material Notes:	MAGNIFIN H-5 MV is a high-purity magnesium hydroxide modified with a proprietary surface treatment. Based on a mineral raw material, the patented process guarantees a regular structure of the crystallite. MAGNIFIN H-5 MV represents a halogen free flame retardant with low smoke emission and high thermal stability up to 340°C. It is recommended for thermoplastic or crosslinked polyolefins and rubber compounds. During decomposition, no toxic or corrosive gases are generated. The surface treatment favors the compatibility between filler and polymer matrix. Processing, mechanical and electrical properties, also flame retardancy in many applications, can be improved. CAS No.: 1309-42-8 EC/EINECS No.: 215-170-3 Information provided by J.M. Huber Corporation
