LNP Lubricomp OCP36A 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.

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.
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.

一直致力于系统和电缆制造商密切合作,制定一个特殊的聚苯(PPS),光纤技术的要求专门定制的成绩。聚苯硫醚8670A61级具有优异的流动特性,使得它作为套管插头,如精细结构设计组件的理想。此应用程序的其他基本属性是非常低的吸水性,在高温下的低蠕变,尺寸稳定性好,甚至在收缩流动性和横向方向。Vectra液晶聚合物还可用于光纤 - 特别是连接器。这里的关键因素是威达的良好的机械性能,甚至在薄壁部分,和*的精度可以与套圈。套圈可以塑造纳入到1-2微米的公差孔进行125微米厚的玻璃纤维注射。这些套圈使用级的Vectra A460,专为这类应用而开发的。

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.
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.
