Brominated Butadiene Styrene Copolymer (Br-BSC)
DESCRIPTION
Br-BSC is the highly effective modern brominated polymeric flame retardant (FR).
Available as white powder or granules.
Main application is in expanded PS (EPS) and extruded PS foam (XPS).
It has an outstanding environmental and health status.
Highly recommended as substitute to the proscribed hexabromocyclododecane (HBCD).
Br-BSC has the same bromine content as HBCD. Therefore its replacement with Br-BSC requires minimal reformulation in current production process.
In EPS/XPS apart from Br-BSC can also be used other brominated FR. However, Br-BSC being a polymer (MW 100.000) is much preferred because more stable and environmentally better evaluated.
Big EPS/XPS producer more and more use Br-BSC.
PRODUCT GROUP
- Flame Retardants
SYNONYMS
Brominated SBS; Benzene, ethenyl-.polymer with 1,3-butadiene, brominated
MAJOR APPLICATIONS
Expanded polystyrene (EPS): used by producers of EPS (EPS beads) mainly applied for construction thermal insulation
Extruded polystyrene foam(XPS): used by producers of XPS foam (plastic converters) or
producers of flame retardant master batches for XPS foam production.
The manufactured plastic parts are thermal- and sound insulating elements like slabs, blocks used in buildings, packaging (with and without thermal insulation function), shock absorbers, etc.
