High
impact polystyrene finds broad applications in housings and TV cabinetry.
Its ease of processing, physical stability, and flame retardability
in brominated fire retardants combine with antimony trioxide to
act as a synergist to either UL-94 V-O or UL-94 V-2 performance
while maintaining good physical properties. The ease of prossessing
formulated HIPS has resulted in its wide use in a variety of injection
molded applications.
Where some
degree of UV stability is required the selection of brominated fire
retardant, pigments, and UV and processing stabilizers are the critical
factors in meeting the end-user's requirements
Where a
non-halogen flame retardant is required, HIPS requires another polymer
such as PPO to achieve the UL-94 V-O flammability requirement. The
addition of this polymer dramatically changes the processing conditions
for injection molding as well as resulting in higher costs for this
type of system, and in general cannot achieve the level of UV stability
which can be reached with selected brominated fire retardant systems.
