Flame retardant fillers for the plastics and rubber processing industry
MARTINAL® special aluminium hydroxides, ground or finely precipitated, can be used as fillers and flame retardants in polymers, which are processed below 200°C. MAGNIFIN® , a high purity magnesium hydroxide, is preferred as a flame-retardant material where the processing temperatures exceed 200 ° C, e.g. for thermoplastic materials and elastomers requiring high process temperatures.
Martinswerk is the world's leading supplier of halogen-free flame-retardant fillers and is the only supplier offering aluminium hydroxide (MARTINAL® standard, ground, low-viscosity, super-fine precipitates) and magnesium hydroxide (MAGNIFIN® finely crystallized).
Advantages of MARTINAL® and MAGNIFIN®:
•   filler and flame retardant in one
•   environmentally friendly
•   halogen-free
•   non-toxic
•   non-corrosive
•   reduced smoke density
•   non volatile
•   inert
•   no effects on pigmentation
•   recyclable
•   economical
Being chemically inert, MARTINAL® is also preferred for a whole range of applications not related to flame retardancy such as: fillers for toothpaste, powder coating and plastics reinforced with glass fibre.

Special aluminium hydroxide (ATH) and magnesium hydroxide (MDH) products, known under the brand-name MARTINAL® and MAGNIFIN® , offer a broad range of halogen-free, non-toxic, environmentally friendly, flame retardant solutions for a wide variety of applications.

The flame retardant effect of MARTINAL® and MAGNIFIN® is based on the endothermic decomposition into aluminium oxide respectively magnesium oxide and water. Only non-toxic and non-corrosive decomposition products are formed.
