DIC.PPS FZ-1130 PPS：
Fuel Cell End PlatesInjection-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.
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.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. Vectra liquid crystal polymer is also used in fibre optics – particularly for connectors.
PPS燃料電池的端板
質(zhì)子交換膜燃料電池組件，包含了約200系列連接細(xì)胞的堆棧。堆棧是通過(guò)端板螺栓連接到一起保存在棧雙極板和壓縮它們之間的墊片一起舉行。干預(yù)絕緣板無(wú)聊歧管喂氫燃料，空氣和冷卻水氧化堆棧，以及刪除單元操作過(guò)程中產(chǎn)生的水。即使與自動(dòng)化加工，兩套板價(jià)格從300美元到500美元。
由于它具有的屬性，以滿足燃料電池環(huán)境中的許多要求，玻璃纖維增強(qiáng)聚苯硫醚是一個(gè)出色的候選人端板材料。它的模具以及，復(fù)制優(yōu)良特性，展品很少翹曲，可以很容易地承受壓縮堆棧所需的負(fù)荷。它具有優(yōu)良的尺寸穩(wěn)定性，并保留其機(jī)械性能遠(yuǎn)遠(yuǎn)高于80°C（176°F）的質(zhì)子交換膜燃料電池的操作溫度。

的開(kāi)發(fā)工作表明，結(jié)合一體注塑成型板和絕緣組件可以減少板的成本，每個(gè)堆疊美元之間，100美元和120，同時(shí)也減少了至少10磅（4.95公斤）棧重量。除此之外，PPS是一個(gè)很好的絕緣體，具有低的熱膨脹，吸收少量的水，是固有的阻燃。重要的是，PPS具有與它接觸流體的電導(dǎo)率的影響不大。注塑月底從公司的聚苯板聚苯硫醚（PPS）在質(zhì)子交換膜（PEM）燃料電池可提供顯著的成本和重量節(jié)省。整合終板和相鄰的絕緣板的設(shè)計(jì)變更可能減少高達(dá)90％相比，目前的燃料電池原型，采用金屬的成本和重量。
Aerospace Wing and Leading Edge Nose
PPS already had all the basic characteristics for use in aircraft construction – resistance to high temperatures and aggressive chemicals, hardness, impact strength, dimensional stability and inherent flame-retardancy. The trick was to create suitable structural elements embodying these attributes. This is done by extruding the PPS into film, combining it with chosen fibrous reinforcements and forming the final part under high pressure at 300°C （572°F）. Individual parts are then fabricated from the pressed composites and welded together in an autoclave to form the final component as one piece.Fiber-reinforced composites based on ’s high performance polyphenylene sulfide （PPS） make an important contribution to weight reduction of the Airbus A340 and A380.This helps lower fuel consumption and increase range and passenger capacity.
