Brominated Polystyrene (BPS)
DESCRIPTION
BPS is polymeric flame retardant (FR) containing thermally stable aromatic bromine.
Appears in powder or granules.
Outstanding application properties of BPS are:
-high thermal stability, therefore favoured for engineering plastics processed at high temperatures
-resistance to yellowing at high temperatures
-good electrical insulating properties
-as polymer it is non-blooming
-insoluble in water and presents no bioaccumulation or dioxin/furan concerns
BPS, like some other brominated FR can be used combined with synergist such as antimony trioxide or antimony chloride
PRODUCT GROUP
- Flame Retardants
SYNONYMS
Benzene, ethenyl-,homopolymer, brominated;
Bromopolystyrene;
4-bromo polystyrene;
Polystyrene resin bromide
MAJOR APPLICATIONS
Compounds, master batches and plastics of:
a) Engineering plastics such as polyesters (PET, PBT, PCT)
b) Polyamides (PA6, PA66).
The plastic parts manufactured from a) and b) are those with higher technical performance used in the fields of automotive, electrical/electronics, machine building, construction, etc. To enhance their properties they can be reinforced by fibers and fillers.
