RTP Compounds 1387 SI 2 PPS
PPS is a high-temperature linear PPS that offers excellent dimensional stability, inherent flame resistance, and excellent chemical and solvent resistance. PPS is insoluble in all known solvents below 200°C （392° F）. It also shows tremendous stability in both typical and alternative automotive fuels. Standard injection moldable grades with glass fibers and/or mineral reinforcements are available, but many specialty grades are available for improved lubricity, low warpage, faster cycling and other areas of enhanced performance.
Ferrule
The crucial factors here are Vectra’s good mechanical properties, even in thin wall sections, and the extreme precision with which ferrules can be made. Ferrules can be injection moulded to incorporate holes to carry the 125 μm thick glass fibres to tolerances of 1-2 μm. These ferrules use Vectra grade A460, specially developed for such applications.
Vectra liquid crystal polymer is also used in fibre optics – particularly for connectors. has been working closely with systems and cable manufacturers to develop a number of special （PPS） grades tailored specifically to the requirements of fibre optic technology. The 8670A61 grade has outstanding flow properties, making it ideal for fine-structured design components such as plug connectors, known as ferrules. Other essential properties for this application are very low water absorption, low creep at high temperatures, good dimensional stability and even shrinkage in both flow and transverse directions.

Injection-molded end plates made from ’s polyphenylene sulfide （PPS） can provide significant cost and weight savings in proton exchange membrane （PEM） fuel cells. Design changes integrating the end plate and the adjacent insulating plate may reduce cost and weight as much as 90% compared to current fuel cell prototypes employing metal.
A PEM fuel cell assembly contains a stack of about 200 series-connected cells. The stack is held together through bolting from the end plates to hold the bipolar plates in the stack together and compress the gaskets between them. Intervening insulating plates have bored manifold to feed hydrogen fuel, oxidizing air and cooling water to the stack, as well as to remove the water produced during cell operation. Even with automated machining, the two sets of plates can cost from $300 to $500. ’s development work suggests that integrated injection-molded plates combining end and insulating components may reduce plate cost to between $100 and $120 per stack while also reducing stack weight by at least 10 lb （4.95 kg）.
