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.
