PPS FZ-3805-A1--- Short-Term Mechanical Properties
DIC.PPS shows excellent mechanical properties over
comparatively wide temperature range. Figure 4.1
shows the tensile stress-strain curves at room
temperature for the representative six grades. Figure
4.2 ilustrates the relationship between tensile strength
and temperature. Also Figs.4.3 and 4.4 show the
relationship between flexural strength and modulus
and temperature respectively. In these figures, over
about 90°C which is glass transition temperature of
PPS, the strength and rigidity gradually fall lowering.
However DIC.PPS retains about 30% of the strength
and modulus at room
temperature even at high
temperature of 200°C. Also cross-linked grade FZ-
1140 shows high rigidity than linear grade FZ- 2140.
