RTP 1379 S PPS
products have been specified in a wide range of injection molded applications such as automotive under-the-hood parts, power train components, pumps, fuel system components, surface mount electrical/electronics components, blower and pump parts, protective and non-stick coatings, surgical devices and power tools. PPS can be extruded or blow molded, may be used to produce films and composites, and is an excellent candidate for fuel cells and diesel fuel cars.

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℉)。PPS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?;诰郾搅蛎褟?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。PPS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?;诶w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。
Baseplate for Video Recorder
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.
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.
CD/MD-Player
In this application, a mechanical property profile tailored to the special operating conditions in a CD/MD player was required, i.e. high elastic modulus and high impact strength.
Vectra was able to meet the necessary requirements without any problem. For the lens holder, on the other hand, the important criterion was lightweight coupled with good rigidity to exclude any disturbing high-frequency resonances.In various CD/MD players for stationary hi-fi equipment, Sony uses moving magnets instead of the usual rollers. Sony refers to this type of drive as the A-MAX system (Advanced Moving Magnet 2 Axis).
In selecting the materials for this technical solution, the Japanese specialist in entertainment electronics together with Polyplastics (the affiliate in Asia) opted for two materials from : Vectra liquid crystal polymer (LCP) and polyphenylene sulphide (PPS).Once again, Vectra LCP was able to meet the application requirements. For the slot for the CD carriage, Sony chose glass-fibre-reinforced . The high rigidity and strength of this easyflowing PPS from were crucial here.Vectra is used to produce the baseplate which is movable along two axes.
