MAGNIFIN® Magnesium hydroxide

Halogen-Free Flame Retardants for the Cable Industry


MARTINAL and MAGNIFIN products are world-renowned as environmentally friendly, halogen-free flame retardants. They are non corrosive, inert, without effect on pigmentation, recyclable and efficient in reducing smoke density.

MAGNIFIN magnesium hydroxide is a high-purity synthetic magnesium hydroxide, Mg(OH)2.  A patented manufacturing process is employed to produce a uniform fine particle size and regular crystal structure. Standard types or specially coated grades are available to ensure superb end-product properties – even at filling levels above 65 percent. MAGNIFIN halogen-free flame retardants are recommended in applications where the processing temperature exceeds the decomposition temperature of aluminum hydroxide, i.e. above 330°C as, for example, in thermoplastics or in high speed processing of elastomers. This also applies where high flame retardant requirements must be met.
