Specialty Polyphenylene Sulfide (PPS) Compound for New Generations of Fiberoptic Connectors

Publisher: Celanese
Discussing about the development of a new linear polyphenylene sulfide (PPS) compound, this paper presents Fortorn 8670A61 advantages such as excellent melt flow, low viscosity, low uniform shrinkage, and minimal moisture uptake. It states that FortronŽ 8670A61 is ideal for small form factor connectors, which have twice the density of the current popular fiberoptic connectors. Also included are tables detailing short term properties of Fortron 8670A61 fiberoptic connector grade, recommended molding conditions for Fortron 8670A61, and relative flash Performance of Fortron. The paper concludes that in order to improve machining and polishing of connectors, by eliminating problems with chip clearance and surface smearing the new grade Fortron 8670A61 would be the best choice.
