PERFORMANCE PROOF - APPLICATIONS
POLYPHENYLENESULFIDE (PPS)
Polyphenylene sulfide (PPS), an organic polymer consisting
of aromatic rings linked with sulfides, is effectively separat-
ed by ultra-high temperature GPC (Figure 6). Synthetic fiber
and textiles derived from this polymer are known to resist
chemical and thermal attack. PPS is used to make filter fab-
ric for coal boilers, papermaking felts, electrical insulation,
specialty membranes, gaskets, and packings. PPS has not
been found to dissolve in any solvent at temperatures be-
low about 200 °C (392 °F).
POLYMETHYLPENTENE (PMP)
The separation of polymethylpentene (PMP), a high perfor-
mance, heat resistant (mp > 200 C) polymer with charac-
teristics similar to polyolefins, is shown in Figure 7. PMP’s
exhibit excellent electrical insulating properties and strong
hydrolysis resistance. One of the principle applications is
for a release film used in the electronics industry.
