Red Phosphorus Flame Retardant RPM440B for Polyamide

Product Description 
  RPM440B 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. 
  RPM440B 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 RPM440, RPM440B has an improved flame retardancy effect.


Applications
  RPM440B 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 10 to 14%(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 13% to 14% 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, CTI折�00V.)

We are one of the most famous manufacturers of Aramid fibe, Silicone Rubber and Red Phosphorus Based Flame Retardant masterbatch in China. For Aramid fiber, there are several grades available for reinforcement in civil industry and military industries; There're LSR and HTV silicone rubbers for especially electrical abd electronic applications.And we have several varied red phosphorus flame retardant masterbatches available to different compound systems as fire proof agent, therefore there?s need concerning about the compatibility. At the same time, we could supply GM Series Of Silicone Additive for Plastics working as lubricant, one component and two components room temperature vulcanized silicone rubber for sealant, adhesive and moulding, MCA, MPP.
