Sell Red Phosphorus Based Flame Retardant RPM240

Product Description                                                                  
      RPM240 is a non -halogenated flame retardant based on red phosphorus, particularly suitable for polycarbonate 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.
      RPM240 is based on stabilized and micro-encapsulated red phosphorus powder grades and styrene-acrylic nitrile copolymer as a carrier resin. It is easy to be homogeneously dispersed in the polymer compound.

      RPM240 is the master batch developed especially for PC, also glass-fiber reinforced, intended to be used for electrical switches, connectors and domestic appliances, etc.

Formulation
      In PC, a recommended dosage should range from 3 to 6% (by wt) based on the weight of polymer, depending on PC grade, processing conditions and the required flame retardancy class.
     Specifically, in PC, a dosage of 4% is usually sufficient to meet the most demanding applications for electrical components (i.e.V-0 at 1.6mm in thickness according to UL94).
