Specification :

ProductDescription RPM460 is a non -halogenated flame retardant based on red phosphorus, particularly suitable for polyamide articles. It is offered as a free-flowing and dust-free master batch in pellets physical form which makes it very easy to handle, accurate to dose and safe to process, allowing high consistency in the quality of the final article.
RPM460 is based on stabilized and micro-encapsulated red phosphorus powder grades and polyamide as a carrier resin. It is easy to be homogenously dispersed in the polymer compound. Compared to RPM440B, RPM460 contains more red phosphorus.

Applications RPM460 is the master batch developed especially for use in polyamides. It is suited for both glass-fiber reinforced and non-reinforced grades. The flame retarded polyamide compounds exhibit very good physical and electrical properties.

Formulation
In glass-fiber-reinforced PA6 or PA66, a recommended dosage should range from 8 to 12%(by wt)based on the weight of polymer, depending on PA grade, processing conditions and glass fiber content and the required flame retardancy class.
Specifically, in PA66 with 30% glass fiber, a dosage of 11% to12% is usually sufficient to meet the high level demanding applications for electrical components (i.e.V-0 at 0.8mm in thickness according to UL94, CTIe400V.)
