LNP Verton OX07411 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.

Baseplate for Video Recorder

Despite the growth of the DVD player market, tape-based videocassette recorders （VCRs） retain an important share of market. Normal product lifecycle cost pressures have driven VCR manufacturers to develop continually lower cost designs for these devices. Typically, the VCR baseplate is produced by outsert molding, with various functional parts such as bearings, guides and fasteners being molded onto the baseplate in a single operation.

Engineers at Toshiba carried this concept even further by combining two different materials – Hostaform acetal copolymer and polyphenylene sulfide （PPS） onto the baseplate. Here the special advantages of these two different materials can be exploited simultaneously, making it possible to replace metal die-castings and reduce the number of assembly steps.

PPS金屬環

 套圈可以塑造納入到1-2微米的公差孔進行125微米厚的玻璃纖維注射。這些套圈使用級的Vectra A460，專為這類應用而開發的。一直致力于系統和電纜制造商密切合作，制定一個特殊的聚苯（PPS），光纖技術的要求專門定制的成績。聚苯硫醚8670A61級具有優異的流動特性，使得它作為套管插頭，如精細結構設計組件的理想。 此應用程序的其他基本屬性是非常低的吸水性，在高溫下的低蠕變，尺寸穩定性好，甚至在收縮流動性和橫向方向。Vectra液晶聚合物還可用于光纖 - 特別是連接器。這里的關鍵因素是威達的良好的機械性能，甚至在薄壁部分，和*的精度可以與套圈。

Fuel Cell End Plates

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）.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.
