...be displayed at the booth. News in Flame Retardants Great Lakes Chemical Co. will feature three new flame retardants for engineering thermoplastic electrical connectors, relays, and switches. Firemaster BP411 is a brominated PS and Firemaster CP-44HF is a polybrominated styrene copolymer (Fig. 8). Each reportedly offers unusual heat stability, flowability, and blister resistance in glass-reinforced PBT and glass-reinforced nylon 6 and 66. Typical use levels are 19% with 6% antimony trioxide for...

...atic polyphosphate), in Europe. Dead Sea Bromine is currently developing PFR-221, a solid aromatic oligophosphate, which is intended for UL 94 V0 (PC+ABS) blends. Great Lakes Chemical Corporation, West Lafayette/USA, has introduced Firemaster 2100, bis-(pentabromophenyl)ethane, as a substitute for decabromodiphenyl ether. This means that Albemarle, which introduced this compound as Saytex 8010 many years ago, is no longer the sole supplier on the market. Prices have thus fallen accordingly. A lo...

...rus-containing flame retardants and synergists based on antimony and zinc borate. A new product presented at K 2004 was Rheogard 2000, a halogen-free, intumescent flame-retardant system for polypropylene, which is not based on ammonium phosphate. Firemaster CP-44HF is a flame retardant based on a copolymer of di/tribrominated styrene and glycidyl methacrylate which has been specially developed for glass-fibre reinforced, high-temperature-resistant polyamide. Its temperature stability makes it su...

Table 2 compares the performance of the industrial flame retardant regarded as standard for automotive foams, tris dichloropropyl phosphate (TDCP), with the product Firemaster BZ-54 (manufacturer: Great Lakes). This is a new, liquid, brominated benzoate ester, a flame retardant introduced as an alternative to pentabromine diphenyl ether. The table shows the weight of volatiles measured when the foam is subjected...

...ranks as the global leader for antimony oxide and other flame retardant synergists. To meet the high demands concerning thermal stability combined with good flow properties, Great Lakes has developed two new flame retardants based on dibromostyrene: Firemaster PBS 64 and PBS 64HW. They are suitable for the flame retardant treatment of industrial plastics such as polyamides and thermoplastic polyesters where these are used for small electronic components and are processed in short cycle times und...
