Sell Red Phosphorus Based Flame Retardant RPM670

Product Description                                                                 
     RPM670 is a non -halogenated flame retardant based on red phosphorus, particularly suitable for polyolefin 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.
     RPM670 is based on stabilized and micro-encapsulated red phosphorus powder grades and polyolefin as a carrier resin. It is to be homogeneously dispersed in the polymer compound. Compared to RPM650, RPM670 contains more red phosphorus.

     RPM670 is the master batch developed especially for use in polyolefin. It is the ideal partner for halogen-free flame-proofing polyethylene (homo-polymer and co-polymer), polypropylene (homo-polymer and co-polymer) articles such as tubes, jackets, profiles, wires, cables, film, etc.

Formulation
                RPM670 is generally combined with one or more synergistic co-agents such as metal hydroxides (Al(OH)3, Mg(OH)2), organic phosphoric esters, expandable graphite, melamine derivatives, etc. A recommended dosage should range from 8 to 12%(by wt)based on the weight of total compositions, depending on the kind of polymers, other flame retardant content and the  required flame retardancy class.
