General & Use:
FyrolflexTM RDP, an oligomeric phosphate ester flame retardant, is designed for use in engineered resin applications such as polyphenylene oxide alloys and PC/ABS. Because of its low volatility and high heat stability, this non-halogen flame retardant can tolerate high temperature processing required of many engineered resins. In addition to its FR characteristics, FyrolflexTM RDP demonstrates improved processing characteristics in a number of thermoplastics including ABS and HIPS that benefits designs like thin wall moldings, and other high-performance, high flow plastic applications. Typically, RDP is used at 8 to 15 phr to provide flame retardancy in a variety of resins. When used as a processing aid, 1 to 3 phr of RDP is added to thermoplastics to improve melt flow characteristics with minimal loss of dimensional stability. Compared to other non-halogen FRs (phosphate esters), FyrolflexTM RDP is relatively stable with low volatility, well within the processing parameters of most engineered plastics (onset decomposition +300° C). FyrolflexTM RDP also has the advantage over other bis-phosphates with its low viscosity. This allows for ease of handling and better and safer management of resources (lower heat storage). Because the reason to use flame retardants is to effect flame retardancy, FyrolflexTM RDP, on a pound for pound basis, has a higher phosphorus content than bis-phenol A bis phosphates which means lower use levels.
