Overview
Generally HIPS is useful for the electric
and electronic applications due to its excellent material
properties. The materials used in electric and electronic
applications must have flame retardant properties
to prevent fire caused by the occurrence of electricity
leakage. In addition, due to legislation regarding
the use of flame retardant materials for fire safety,
there has been a steadily increasing demand for flame
retardant products.
When dealing with plastic material for fire retardant,
the following general approaches are available: design
of the basic polymers and incorporation of chemicals.
For many plastic materials, the most feasible method
of improving their nonflammability available flame
retardants such as halogen compounds(Br, Cl, etc).
Cheil Industries Inc. produces various grades of starex
Flame Retardant HIPS through the advanced production
technology. |
Properties
1) Mechanical
In general, molded products may experience crack,
warpage or cause various problems depending on the
injection molding conditions or environmental conditions.
Starex Flame Retardant HIPS shows stable impact strength
and flexural characteristics at high temperatures
as well as at low temperatures so that proper grades
may be chosen depending on the user's intentions.
2) Thermal
The excellent thermal stability of starex Flame Retardant
HIPS promotes a wide range of applications. Each grade
is exhibits different levels of deformation, and thus
a careful selection of grade is necessary according
to the environment, that is, the maximum temperature
ranges of the molded product should be given great
consideration.
3) Flow
Starex Flame Retardant HIPS displays excellent melt
flow characteristics with balanced material properties
to meet the customer's needs. Such characteristics
support productivity improvements and flexibility
in the design process for molded products that features
large sizes and complicated geometrical shapes.
4) Weather resistance
There has been a growing demand for the use of weather
resistant flame retardant grades in electrical and
electronic equipment. Starex Flame Retardant HIPS,
with its excellent weather resistance and flame retardant,
is very useful for applications requiring those characteristics.
