AIE PPS R70描述:
f your design challenges require high temperature stability, broad chemical resistance, stiffness. strength and creep resistance at elevated temperature, consider Polyphenylene Sulfide (PPS).
PPS
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. Certain grades of PPS comply with ISO 10993 and USP Class VI, and Drug (DMF 14844) and Device (MAF-1097) Master Files have been created for them. These grades also meet European Directive 2002/72/EC for food contact applications and BfR (German Federal Institute for Risk Assessment , formerly BgVV, the German Federal Institute for Consumer Health Protection and Veterinary Medicine) standards.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).航天用品
聚苯硫醚已經(jīng)有飛機建設(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制造中的應(yīng)用,包括機翼的鼻子,副翼和飛機龍骨梁。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A340和A380飛機的重量減少。這有助于降低油耗和增長幅度和客運能力。

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.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.
