As a new environmentally friendly brominated flame retardant, SBS bromide is easier to shape in mechanical processing than hexabromocyclododecane, and SBS brominated SBS in the melting mixture, injection into mold, extrusion foam process conditions, the bearing force is very small, almost no thermal degradation, the process temperature can reach more than 230 °C, thermal stability is better, in addition, the flame retardant of the present invention has good compatibility, will not have a negative impact on the mechanical properties of the added material, etc., can be used as a good substitute for hexabromocyclododecane.
 The innovative brominated polymerization flame retardant BR-SBS has a variety of excellent properties and is an alternative to HBCD, Br-SBS has the following advantages: 
This product is a stable high molecular weight polymer 
It can be shared with the synergist in the current EPS/XPS flame retardant system 
It is not easy to absorb moisture, which helps to reduce the residual water content of EPS beads and improve production efficiency 
Under the same bromine content conditions, the flame retardant performance of Br-SBS in polystyrene foam is comparable to that of HBCD 
The polymer structure makes it difficult to be absorbed by organisms, eliminating environmental concerns
