From Ticona Engineering Polymers
The processing considerations and potential applications for two different semicrystalline
engineering polymers in extrusion are described. Specifically, they include
Polyphenylene Sulfide (PPS) and Polybutylene Terephthalate (PBT). All the described
applications fall under the category of extruded substrates such as spunbonded and
meltblown nonwovens, staple fibers, monofilaments, multifilaments, nettings, films and the like. The chemical structures of these polymers, their physical and chemical
properties, and their inherent features and benefits are described in conjunction with key
drivers that are making them find applications in the extrusion arena. Examples of various substrates are presented and comparisons made to traditional polymers.
