icona has introduced four Fortron® polyphenylene sulfide (PPS)
grades with up to ten times the thermal conductivity of standard, filled
PPS grades for use where heat dissipation and other thermal
management issues are important. These resins have thermal
conductivities ranging from about 1.1 to 3.0 W/mK and are available in
grades for electrically insulated and thermally conductive applications.
The new PPS line provides an optimum combination of cost,
performance and thermal conductivity. Although the resins have lower
thermal conductivity than metal, designers can use them for essential
heat dissipation while retaining many of the traditional benefits of PPS.
These benefits include chemical resistance, design freedom and
dimensional stability, as well as possibilities for part consolidation and
The new Fortron resins can be used in many industries in several
potential applications such as heat sinks, heat pipes, pumps, tubing,
electronic interfaces and power supply units. Their typical end uses
include high-intensity light fixtures, transformer thermal emission
bases in power integrated circuits and optical pick-up bases.
Fortron PPS is a linear material that, when compared to highly
branched PPS products, offers greater strength and toughness for more
versatility in part design and assembly, as well as better end-use
