Sumikon FM-MK120J PPS
Fiber and monofilament made from PPS can be found in woven or mesh conveyor belts, flame resistant clothing and filtration media. also offers unfilled, high viscosity PPS suitable for extrusion and compression molding to produce slabs, rods and other stock shapes commonly used for prototyping. linear PPS may be used with meltblown and spunbond technologies for melt spun nonwovens.
Ferrule
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.
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.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.

聚苯硫醚已經(jīng)有飛機(jī)建設(shè)使用的所有基本特征 - 抗高溫和腐蝕性化學(xué)物質(zhì)，硬度，沖擊強(qiáng)度，尺寸穩(wěn)定性和固有的阻燃阻燃。訣竅是創(chuàng)造合適的結(jié)構(gòu)元素，體現(xiàn)這些屬性。這是通過(guò)擠壓成片的聚苯硫醚，相結(jié)合，選擇纖維增援，形成高壓下的zui后一部分，在300℃（572℉）。的各個(gè)部分，然后從按下的復(fù)合材料和制造，焊接在一塊形成的zui后一個(gè)組件一起反應(yīng)釜。
基于聚苯硫醚復(fù)合材料現(xiàn)在被用于許多在飛機(jī)制造中的應(yīng)用，包括機(jī)翼的鼻子，副翼和飛機(jī)龍骨梁。與鋁相比，使用的聚苯硫醚復(fù)合材料提高了設(shè)計(jì)的自由度，降低了20％至50％的重量和消除腐蝕的可能性。基于纖維增強(qiáng)復(fù)合材料泰科納高性能聚苯硫醚聚苯硫醚（PPS），作出了重要貢獻(xiàn)的空中客車(chē)A340和A380飛機(jī)的重量減少。這有助于降低油耗和增長(zhǎng)幅度和客運(yùn)能力。
Fuel Cell End Plates
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）.
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.Injection-molded end plates made from ’s polyphenylene sulfide （PPS） can provide significant cost and weight savings in proton exchange membrane （PEM） fuel cells.
