Brominated Polystyrene

Chemical formula:
Application:（C8H5.3Br2.7）n 
This flame retardant provides outstanding thermal stability and electrical performance. It is particularly suitable for engineering plastic applications such as polyesters(PET,PBT,PCT)and polyamides(nylons).It has outstanding thermal stability , it is an ideal choice for high temperature applications such as engineering plastics . Due to its stability , it can often be used where other flame retardants fail to survive . Due to its polymeric structure , it is nonblooming in all applications . Excellent electrical properties provide yet another reason to choosethis flame retardant for demanding engineering plastic 
applications.
