Celstran PPS-AF35-01-US PPS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
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. 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.航天用品
基于聚苯硫醚复合材料现在被用于许多在飞机制造中的应用,包括机翼的鼻子,副翼和飞机龙骨梁。与铝相比,使用的聚苯硫醚复合材料提高了设计的自由度,降低了20%至50%的重量和消除腐蚀的可能性。基于纤维增强复合材料泰科纳高性能聚苯硫醚聚苯硫醚(PPS),作出了重要贡献的空中客车A340和A380飞机的重量减少。这有助于降低油耗和增长幅度和客运能力。
聚苯硫醚已经有飞机建设使用的所有基本特征 - 抗高温和腐蚀性化学物质,硬度,冲击强度,尺寸稳定性和固有的阻燃阻燃。诀窍是创造合适的结构元素,体现这些属性。这是通过挤压成片的聚苯硫醚,相结合,选择纤维增援,形成高压下的zui后一部分,在300℃(572℉)。的各个部分,然后从按下的复合材料和制造,焊接在一块形成的zui后一个组件一起反应釜。

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.
