Latilub GF 30 PPS
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.
Aerospace Wing and Leading Edge Nose
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.
Composites based on PPS are now being used for numerous applications in airplane construction, including the wing nose, the ailerons and the aircraft keel beam. In comparison with aluminum, use of the PPS composites increases design freedom, reduces weight by 20% to 50% and eliminates the possibility of corrosion.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.
PPS金屬環
這里的關鍵因素是威達的良好的機械性能，甚至在薄壁部分，和*的精度可以與套圈。套圈可以塑造納入到1-2微米的公差孔進行125微米厚的玻璃纖維注射。這些套圈使用級的Vectra A460，專為這類應用而開發的。一直致力于系統和電纜制造商密切合作，制定一個特殊的聚苯（PPS），光纖技術的要求專門定制的成績。聚苯硫醚8670A61級具有優異的流動特性，使得它作為套管插頭，如精細結構設計組件的理想。此應用程序的其他基本屬性是非常低的吸水性，在高溫下的低蠕變，尺寸穩定性好，甚至在收縮流動性和橫向方向。Vectra液晶聚合物還可用于光纖 - 特別是連接器。
errule
These ferrules use Vectra grade A460, specially developed for such applications.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. 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.
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.
