Masteret® – Red Phosphorus Based, Non-Halogenated Flame Retardants


Masteret is a non-halogenated flame retardant based on red phosphorus. It is mainly used where moulded final fireproofed articles with outstanding properties are needed, in particular areas where good mechanical properties together with very high electrical properties are required and where the natural red or black pigmentation are acceptable. The main applications include electric installation systems, industrial switching units, household electrical equipment, automation technology and automotive.


Masteret was introduced by Italmatch Chemicals in 1996 and gave the engineering plastic industry a boost in the area of high-level flame retardancy technology, especially in the polyamide field. Masteret product range has traditionally been geared to improve red phosphorus processability, simplifying tasks, reducing costs and improving quality for the final customer. Masteret technology allows a completely safe transportation, handling and incorporation of red phosphorus.
