Sell Red Phosphorus Based Flame Retardant RPM440

Product Description                                                                                
      RPM440 is a non -halogenated flame retardant based on red phosphorus, only suitable for glass fiber reinforced 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.
RPM440 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.

RPM440 is the master batch developed especially for use in polyamides. It is suited for glass-fiber 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 12 to 18%(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 15% to 16% is usually sufficient to meet the most demanding applications for electrical components (i.e.V-0 at 1.6mm in thickness according to UL94, CTI﹥400V.)
